Abstract:

SiCp/Al composite was fabricated by the method of pressureless-infiltration. In atmospheric environment, the atmospheric corrosion behavior of SiCp/Al composites (ZL101+49%SiC+5%Mg) was studied by mass loss, optical microscope (OM), scanning electron microscope (SEM), X-ray diffraction (XRD), energy dispersive spectrometer (EDS) and Fourier transform infrared spectroscopy (FTIR), respectivelhy.The results show that the corrosion rate of the SiCp/Al composites increases with increasing of time in atmospheric environment. Pitting corrosion is the main characteristic of SiCp/Al composite, and corrosion area gradually extends around with time increasing. At last, sheet like corrosion substrates distribute in the surface of n the SiCp/Al composites. Amorphous Al2O3 and amorphous AlxSO4yOHz are the main corrosion products.

Abstract:

In this paper, SiCp/Al composites were fabricated by spontaneous infiltration technology. The micro-deformation behavior (MDB) of low tress in some silicon carbide particulate reinforced aluminum composites (SiCp/Al composites) was investigated experimentally. The microstructure, micro-deformation of samples was analyzed by OM and WDW-50 respectively. The results show that, in aluminum matrix with incorporating SiCp, the distribution of SiCp was uniform. In the same other conditions, SiCp size of the composite plays an important role on MDB at low stress, and the micro-deformation performance of the SiCp/Al composite increases with decreasing of SiCp size. MDB of composites at low stress deeply depends on the matrix material, and MDB increases with increasing of the matrix strength. It was also found that, the micro-deformation of SiCp/Al composite was negative value in the early stages of low tensile stress, and the phenomenon can be explained by strain relaxation.

Abstract:

SiCp/Al composites were fabricated by ceramic mold freedom infiltration and pressureless infiltration, respectively. The microstructure and phases are analyzed by metallurgical microscope and coefficient of thermal expansion of SiCp/Al composites were tested by thermal dilatometer. The results show that SiCp/Al composites are compact and uniform. SiC particles were dispersed uniformly in Al matrix, and SiCp segregation was not found in composites. Under a certain SiCp size range, space between SiCp decreases with decreasing of SiCp size, and CTE of SiCp/Al composites also decreases with decreasing of particles size. Compared with CTE of composite with pure aluminum as matrix, CTE of composite with ZL101 as matrix is less. Under the annealing process, CTE of SiCp/Al composites with ZL101 as matrix is less than that with the solution and aging, which indicated that its dimensional stability of resisting to temperature fluctuation is better, and thermal expansion behavior and characteristic of SiCp/Al composites are also better.

Full text

Abstract:

By properly proportioned SiC particles with different sizes and using squeeze infiltration process, SiCp/Al composites with high volume fraction of SiC content (Vp = 60.0%, 61.2%, 63.5%, 67.4%, and 68.0%) were achieved for optical application. The flexural strength of the prepared SiCp/Al composites was higher than 483 MPa and the elastic modulus was increased from 174.2 to 206.2 GPa. With an increase in SiC volume fraction, the flexural strength and Poisson’s ratio decreased with the increase in elastic modulus. After the anodic oxidation treatment, an oxidation film with porous structure was prepared on the surface of the composite and the oxidation film was uniformly distributed. The anodic oxide growth rate of composite decreased with SiC content increased and linearly increased with anodizing time.

Abstract:

Al alloy reinforced with SiCp (size: 70-220μm) was fabricated by pressureless-infiltration. Its wear resistant property was investigated under different heat-treatment conditions, and morphology of worn surface was examined. The results showed that the composite was integrated, uniform and compact, and its wear resistant property was better than that of the unreinforced matrix alloy. It was indicated that some rigid SiCp in the abraded surface of the composite could support part of loads and replace matrix to wear-tear, which improved the wear resistant property. Compared to annealing, solution aging strengthens Al alloy matrix and cohesion with SiCp, and the wear resistant property of composites was better. Combining interface is also an important factor which influences on wear resistant property. During the wear test, the smaller SiCp size, the more interfaces, there are more SiCp falling off because of loosening combining interface, which results in more wear-tearing value. The wear rate of composite increases with decreasing SiCp size, thus, the composite with larger SiCp has better wear-resistant property than that with smaller SiCp. At last, the wear mechanism of the composite was also studied, and it showed that abrasive wear dominated in the abrasion process.

Abstract:

It is well known that the mechanical and deformation properties of metal matrix composites (MMCs) are related to their microstructures. However, less work has been carried out in laser bending to examine the dependency of microstructures of MMCs on deformation behaviour. In this paper, two aluminium-based metal matrix composites, Al2009/20 vol% SiCw and Al2009/20 vol% SiCp were investigated. A YAG laser was used to scan the composites both parallel and perpendicular to their rolling directions. It was reported that under the same processing conditions, a larger bending angle was obtained for the Al2009/SiCp composite. No significant change in microstructures was observed for both composites after bending. Experimental findings also revealed that for the particulate reinforced composite, a larger laser bending angle was obtained when the laser scanning direction was perpendicular to the rolling direction, whereas no significant difference was observed for the Al2009/SiCw composite. These phenomena were shown to relate to the shape and distribution of reinforcements.

ZL101 Al alloy reinforced with 55% silicon carbide particulate metal-matrix SiCp/Al composite has been fabricated by pressureless-infiltration. The microstructure characterization of composite has been studied by optical microscope (OM), scanning electron microscope (SEM), X-ray spectroscopy (EDX), respectively. The results show that the SiCp are uniformly distributed in Al alloy matrix, however, there are some casting defects such as shrinkage and gas porosities in the matrix. When Mg was added into the composite, it can improve wettability property of between Al matrixes and strengthen particle SiCp and decrease micro-defects such as gas porosities, the Microstructure of SiCp/Al composite prepared was compact and uniform. The SiCp particles evenly distributed in the matrix and without significant partial segregation phenomenon. It improves the whole performance of the composites.

Abstract:

Nondestructive eddy current methods were used to evaluate the electrical conductivity behavior of silicon-carbide particulate (SiCp) reinforced aluminum (Al) metal-matrix composite extrusions. The composites investigated included 2124, 6061, and 7091 Al base alloys reinforced by SiCp. The composite extrusions exhibited anisotropic conductivities with the maximum conductivity occurring along the extrusion plane. Microstructural characterization showed that the observed anisotropic conductivities could result from the preferred orientation distribution of SiCp. A theoretical model was formulated to quantify the influence of composite constituents (SiCp, intermetallics, and Al base alloy) on the anisotropic conductivities of the composites. The theoretical predictions of conductivities were found to be in good agreement with the experimental results.

Abstract:

Abstract In order to effectively meet the actual industrial production standards and improve the prediction accuracy of composite surface roughness, a prediction model of SiCp/Al composite surface roughness based on neural network is proposed. The influence parameters of surface roughness of SiCp/Al composites are analyzed from the cutting tool parameters, and the mathematical calculation of surface roughness of SiCp/Al composites is carried out. Using neural network technology, by determining various parameters of neural network, collecting and processing various data of material surface, the surface roughness prediction model of SiCp/Al composite is constructed to realize the surface roughness prediction of SiCp/Al composite. The experimental results show that the maximum error between the actual value and the predicted value of the surface roughness of composite materials from the prediction model established in this paper is only 0.013, and the average error percentage between the actual value and the predicted value is 0.705%, which can effectively improve the prediction accuracy of the surface roughness of composite materials and meet the standards of actual industrial production.

Full text

Abstract:

The pure Cu coating was plated on the surface of silicon carbide particles (SiCP) by two different methods, hydrazine hydrate direct reduction method and hydrazine with glucose pre-reduction method. The hydrazine with glucose pre-reduction method is more suitable for Cu plating on the surface of SiCP in terms of morphology and microstructure. AZ61 composites reinforced with different volume fractions (3~15%) uncoated and Cu-coated SiCP were prepared by powder metallurgy followed by hot extrusion. The effect of Cu coating on the morphology of SiCP/AZ61 composite was analyzed by optical microscope (OM), scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), electronic probe micro-analyzer (EPMA) and X-ray diffractometer (XRD). The properties of the composite were characterized by Brinell hardness tester and mechanical testing machine. The effects of Cu coating on the micro-hardness, tensile strength and elongation of SiCP/AZ61 composite were analyzed. The tensile strength of AZ61 composite reinforced with Cu-coated SiCP increased by 3.5~6.3% and the elongation increased by 7.4~35.0% compared with AZ61 composite reinforced with uncoated SiCP. Therefore, the Cu coating can ameliorate the microstructure and properties of the SiCP/AZ61 composite effectively, reduce the defect rate in the composite, and improve the hardness, relative density, tensile strength, elongation of the composite.

Abstract:

The microstructural structures of SiCp/AZ61magnesium matrix composite were studied in three different casting processes, and their hardness was measured. The results indicated that SiCp/AZ61 composites fabricated in stirring melt casting process, compared to those in fully liquid stirring casting process and in semi-solid stirring casting process, possessed fairly uniform distribution of SiC particulates and few porosity rate. It was an ideal metal matrix composites fabricated process. The Vickers hardness of non-reinforcement AZ61 magnesium alloy is higher than that of semi-solid billet, and the Vickers hardness of SiCp/AZ61 composite is obviously higher than that of the matrix. In the meantime, the Vickers hardness of SiCp/AZ61 composite can be continuously enhanced with an increasing of volume fraction of SiC particles.

Abstract:

A cylindrical ingot was produced by means of centrifugal casting using 20 vol.% SiCp/Al composite melt. The melt which was fabricated by double stir-casting method, consisting of three different sizes of SiC particles. SiCp/Al composites were characterized by optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD) techniques. The results showed that SiC particles in the 20 vol.% SiCp/Al composite melt migrated towards the outer periphery of the cylindrical ingot under centrifugal force. High reinforcement content SiCp/Al composites were obtained in a zone near the outer periphery of the cylindrical ingot, and the volume fraction of SiC particles reached up to 55%. The thermal expansion test was performed, and the coefficient of thermal expansion (CTE) of the 55 vol.% SiCp/Al composites was found to be 9.9 × 10−6/°C, which was lower than the predicted value based on Kerner’s model and that of 60 vol.% SiCp/Al composites fabricated by conventional processing techniques. This article presented an approach for producing high reinforcement content SiCp/Al composites.

Abstract:

Relatively low compactness and unsatisfactory uniformity of reinforced particles severely restrict the performance and widespread industry applications of the powder metallurgy (PM) metal matrix composites (MMCs). Here, we developed a combined processing route of PM and equal channel angular pressing (ECAP) to enhance the mechanical properties and wear resistance of the SiCp/Al-Si composite. The results indicate that ECAP significantly refined the matrix grains, eliminated pores and promoted the uniformity of the reinforcement particles. After 8p-ECAP, the SiCp/Al-Si composite consisted of ultrafine Al matrix grains (600 nm) modified by uniformly-dispersed Si and SiCp particles, and the composite relative density approached 100%. The hardness and wear resistance of the 8p-ECAP SiCp/Al-Si composite were markedly improved compared to the PM composite. More ECAP passes continued a trend of improvement for the wear resistance and hardness. Moreover, while abrasion and delamination dominated the wear of PM composites, less severe adhesive wear and fatigue mechanisms played more important roles in the wear of PM-ECAP composites. This study demonstrates a new approach to designing wear-resistant Al-MMCs and is readily applicable to other Al-MMCs.

Abstract:

AbstractThe present work aims to research the treatment processing of magnesium reinforced with 1 μmsilicon carbide particle (SiCp) using stir casting combined by ultrasonic vibration. Present studies have been done on six different materials: (a) AZ31B alloy without particles, (b) 5 vol.% SiCp/AZ31B composites fabricated with different semi-solid stirring time (5 min, 10 min, 15 min and 20 min), (c) composite with 20 vol.% SiCp. The effects of 1 μm/SiCp pretreatment and stirring time on microstructure and interfacial wettability as well as mechanical properties of the materials were confirmed. Both short and long stirring time for the particle dispersion brought particle agglomeration. Results of SEM microstructure and tensile properties exhibited that the optimal stirring parameters of 625 °C/1500 rpm/15 min are exploited, and 20 vol.% SiCp/AZ31B composite was fabricated by the optimal stirring parameters. The application of optimal stirring parameters for the treatment resulted in homogeneous particle distribution. The addition of SiCp leads to a reduced matrix grain, and 20 vol.% SiCp/AZ31B composite showed smaller grain size than. 5 vol.% SiCp/AZ31B composite. The interface between SiCp and matrix is clear and interfacial wettability well. Tensile test results show that with increasing SiCp content, strengths increase while ductility decreases.

Abstract:

SiCp/A356 composites containing 20% (volume fraction) SiC and three kinds of different filler metals were investigated by vacuum brazing process. Brazability of SiCp/A356 composites was analyzed after nickel plating on the surface of composites and without nickel plating process. The effects of holding time on microstructure of the brazed joints of SiCp/A356 composite were studied by metallographic microscope, SEM and Energy spectrum analysis. The results showed that nickel plating on the surface of composite contributed to improve brazability of SiCp/A356 composites prominently, while inferior brazability displayed without nickel plating on the surface of composites. Hardness of joints brazed at holding time of 6 min, 8 min and 10 min were studied, consequently the hardness of the weld seam region is the highest when the holding time was 8 min.

Abstract:

In this work Al-7wt%Si-10wt%SiCp composites were produced by injection of the reinforcement in the form of SiCp particles or a specially made particulate composite powder of aluminum and SiCp into the melt of proper composition at a temperature corresponding to 10% solid fraction. This paper presents the results of the investigation on the effects of reinforcement addition form, reinforcement addition temperature, stirring speed and magnesium addition on the incorporation and distribution of the reinforcement particles. The results showed that incorporation of SiCp particles was considerably improved by their injection in the form of milled Al/SiCp composite powder. Better particle wetting, improved particle dispersion and reduced particles size were achieved by injection of milled Al/SiCp composite powder instead of SiCp powder. Magnesium addition and high temperature injection were necessary for achieving good incorporation. Reinforcement incorporation was improved by increasing the stirring speed up to 500 rpm, after which the incorporation decreased slowly.

Abstract:

SiCP/Cu composite was prepared by metal injection molding process. Microstructure, mechanical properties, fracture surface, and wear resistance of SiCP/Cu composite were investigated in this study. The research results show that SiCP/Cu were sintered sucessfully by the sintering process with hydrogen protection and high temperature of 1050°C. The tensile strength of the composites depends on the fraction and distribution of SiC particles which is resulted from microcracks nucleate in the matrix between SiC particles because of SiC particle aggregation. The tensile strengths of 5vol.%, 10vol.%, and15vol.%SiCP/Cu are 254MPa, 291MPa and 278MPa separately. SiC particles are contribute to enhance the abrasive resitance of the composite when particle volume fraction increase from 10% to 15%.

Abstract:

The in-house developed bismuthate glass and the SiCp/Al composites with different volume fractions of SiC particles (namely, 60 vol.%, 65 vol.%, 70 vol.%, and 75 vol.%) were jointed by vacuum hot-pressing process. The novel material can be used for the space mirror. The SiCp is an abbreviation for SiC particle. Firstly, the SiCp/Al composites with different vol.% of SiC particle were manufactured by using infiltration process. In order to obtain a stable bonding interface, the preoxide layers were fabricated on the surfaces of these composites for reacting with the bismuthate glass. The coefficient of thermal expansion (CTE) was carried out for characterizing the difference between the composites and bismuthate glass. The sealing quality of the composites and the bismuthate glass was quantified by using shear strength testing. The optical microstructures showed the particles were uniformly distributed in the Al matrix. The SEM image shows that a smooth oxidation layer was generated on the SiCp/Al composite. The CTE testing result indicated that the higher the vol.% of the particles in the composite, the lower the CTE value. The shear strength testing result disclosed that SiCp/Al composite with relatively low CTE value was favorable to obtain a bonding interface with high strength.

Abstract:

Due to the introduction of silicon carbide reinforcement, the physical and cutting properties of SiCp/Mg composites are very different from those of metal composites. Nanosecond pulse laser processing is more efficient than traditional processing for SiCp/Mg composites. A low-power pulsed fiber laser was used to etch 3.0 mm thick SiCp/Mg composites. The effect of low laser power (0~50 W) on the morphology and heat-affected zone of the SiCp/Mg composite after etching was studied. The results show that when the laser power increases, the material accumulation at the ablation end of the machining surface becomes more and more serious. With the increase in power, the differences in ablation width and ablation depth on the surface of composite materials do not increase proportionally. When the laser power increases gradually, the width of the heat-affected zone increases in the direction of the perpendicular laser beam and reaches the maximum value at the etched end.

Abstract:

The creep behaviors of 20 vol% SiCw/2124Al, extruded with different ratios, and SiCp/2124Al, reinforced with 10–30 vol% SiC particles, were investigated to clarify the effects of aspect ratio, alignment, and volume fraction of reinforcement on creep deformation. The effective stresses on the matrix of SiC/Al composites are calculated based on the generalized shear-lag model. The minimum creep rates of SiCw/2124Al extruded with different ratios and SiCp/2124Al reinforced with different volume fractions of SiC particles are found to be similar under a same effective stress on matrix, which is calculated by the generalized shear-lag model. The subgrain sizes in matrices of crept SiC/Al composites are dependent on the effective stress on matrix but not on the applied stress on the composite. It is suggested that the role of SiC reinforcements is to increase the creep resistance of SiC/Al composite by reducing the effective stress on matrix.

Abstract:

Aluminum composites containing 10wt. % of Al2O3 with 3 µm size of particles have been produced using powder metallurgy (PM) method and wear behavior of the composites were tested under dry condition. A comparison is also made with SiCp reinforced Al composite produced at the same conditions. The wear rate of both types’ composites increased with all applied loads, but wear rate of the composites was a strong function of normal load rather than that of type of particles used for the manufacturing MMCs. Furthermore, the wear rate of Al-Al2O3 composite was smaller than that of Al-SiCp reinforced composite, but not indicating significant differences on it. Moreover, SEM examination showed that plastic deformation was the dominant type of wear for the Al2O3 particle reinforced MMCs, but the fragmented-deformed layer of particles was more effective for the SiCp reinforced MMCs due to more fracturing of particles.

Abstract:

Stir casting is a near net shape process that can cast the composite components directly. Fluidity is an important factor for mold filling in casting process, but the fluidity of composite slurry is poor due to the addition of SiCp. In this research, SiCp/A357 composites with 20wt.% SiCp were manufactured by mechanical stir casting. Effect of mechanical stirring and air pressure on the fluidity of SiCp/A357 composites were investigated with eight thin flow channels. The fluidity was compared at different rotating speed and air pressure. The results showed that the fluidity increased with rotating speed, which was more obvious in semi-solid interval. It was noticed that the fluidity decreased with air pressure, the gas involving and the cooling speed were aggravated with air pressure increasing, which reduced the fluidity.

Abstract:

The tensile behaviour of nanometric SiC particulate (SiCp) reinforced aluminium matrix composites (AMCs) was examined at room temperature, 215°C and 350°C. These AMCs were produced via powder metallurgy (P/M) using Al 7075 powder reinforced with different volume fractions (1 vol.%, 3 vol.% and 5 vol.%) of nano-SiCp. The experimental results exhibit that at room temperature un-reinforced Al has both maximum strength and ductility whereas the 5 vol.% SiCp/Al composite has only maximum stiffness. Similar trends were obtained for tests performed at 215°C. However at 350°C, the 1 vol.% SiCp/Al composite has the highest stiffness. Optical microscopy and scanning electron microscopy were performed for microstructure study, examination of the SiCp distribution in the Al matrix and fractography.

Abstract:

The synthesis of agro-waste reinforced metal matrix composites is now very common among researchers because of their cost effectiveness, excellent properties and wide industrial applications. This study synthesized a hybrid aluminium 6061 matrix composite with particulates of silicon carbide, SiCp and carbonized coconut shell, CCSP as reinforcement combined in the ratio 1:1, determined the effect of combining SiCp and CCSp reinforcements of different sizes and weight fractions on the density, hardness, strength properties and microstructure of the developed composite. The hybrid aluminium matrix composites were developed using the stir casting method. Several samples of the composites consisting of AA6061 alloy with 3, 6, 9, 12 and 15% by wt. each of each of the combined CCSp and SiCp with different particle sizes were produced and characterized. Also, mathematical models were proposed for predicticting hardness and tensile strength of the nano-composite and validated by comparison with results of the physical experiment and those of other authors. The results obtained showed that addition of CCSp and SiCp reinforcement to the alloy decreased its density but increased the hardness and tensile strength of the composite. The nano-particulates reinforced composite presented maximum improvement in hardness and ultimate tensile strength values and decreased density value. The microstructures of the developed composite materials revealed uniform distribution of reinforcing particles in the base matrix and excellent bonding between the base matrix and reinforcements after casting. The proposed models were in excellent agreement with experimental data. The developed composite should be suitable for high strength/light weight applications required in the automobile and aerospace industries.

Abstract:

Aluminum matrix composites reinforced with SiC particles (SiCp) were prepared by electromagnetic stirring. This article aims to study the effects of SiCp addition on microstructure and mechanical properties of SiCp/ZL105, finally leading to expended range for ZL105 alloy application. Microstructural studies were carried out by optical microscope, scanning electron microscopy, and energy dispersive spectrometer. Tensile and hardness tests were conducted in order to identify mechanical properties. It was found that addition of 1.5 wt% SiCp causes the refined microstructure (including primary α-Al and eutectic Si) and reduced secondary dendrite arm spacing of α-Al matrix (12.6 μm). Compared to the ZL105 alloy, the ultimate tensile strength, elongation, and hardness of the composite with 1.5 wt% SiCp were increased by 24.6%, 37.3%, and 27.0%, respectively. The improved mechanical properties can mainly be attributed to the refinement of primary α-Al and eutectic Si, and uniformed dispersion of SiCp. Furthermore, the effects of voltage and agitation frequency of magnetic field on microstructure of composites were discussed.

The fabrication process and fracture characterization of 35 and 65 vol% SiCp particulate-reinforced Al matrix (SiCp/Al) composites have been investigated. SiCp composites having different volume fractions of the n-SiCp were synthesized via by pressureless-infiltration at near-net-shape route and were uniaxially tested at room temperature. The SiC particles were mixed with silicasol as an inorganic binder in distilled water. The mixtures were consolidated in a mold by pressing and dried in two step process, followed by calcination at 1000 °C. The SiCp/Al composites were fabricated by the infiltration of Al melt into SiC performs. The experimental results show that volume fraction of reinforced particles in SiCp/Al composites had a significant influenec on fracture section surface characterization in tensile tests. Composite with 45 vol% SiCp, fracture was firstly happen in Al matrix, shallow dimples and intergranular fractures were seen in all the fractographs. With increasing of vol% SiCp, fracture was more brittle in appearance in the composites and the fracture surfaces were flat and less plastic deformations.

Abstract:

Effects of 20-40 vol.% SiCp additions on microstructure and hardness of aluminum composites have been investigated in this research. The composites were produced via powder injection molding at 170°C followed by solvent debinding and sintering at 700-820°C. After sintering, composite microstructures and properties were influenced by SiCp additions and sintering temperatures. Higher SiCp additions required higher effective sintering temperatures. Furthermore, increasing SiCp content promoted SiCp agglomeration along aluminum grain boundaries and caused SiCp pull-out during metallurgical preparation. This resulted in higher porosity observed from the sintered microstructures. Variation in macro Vickers hardness values were obtained due to opposing effects of increasing contents of SiCp and porosity. Optimum hardness values were obtained when sintering was carried out at 740, 780 and 800°C for 20, 30 and 40 vol.% SiCp additions respectively.

Abstract:

The paper presents the results of investigation on physical, mechanical and wear properties of SiC particulate reinforced aluminium metal matrix composite. The influence of reinforced ratios of 10, 15 and 20 wt. % of SiCp on mechanical properties and wear characters was examined. The effect of load and sliding velocity on wear behavior of composite was studied. It was observed that increase of weight fraction of reinforcement produced better physical and mechanical properties such as density and hardness with 37 µm SiC reinforced composite inspite of increased density the hardness drops above the critical sintering temperature of 550°C due to crazing of the matrix. With increased size of SiCp especially with higher temperature, density and hardness doesn’t supplement each other. Possible pooling/agglomeration in the case of medium and coarse sized reinforcement account for this. Wear decreases with increase in sintering temperature for 23 and 37 µm SiCp reinforced composites where as it increases for 67 µm SiCp reinforced composites. This could be attributed to formation of silanium compound contributing to discrete hardening of matrix. Wear tends to drop with sliding velocity being less contact between the pin and the disc but increases with normal load acting on the composite.

Abstract:

The hot deformation behaviors of 30%SiCp/2024 aluminum alloy composites was studied by hot compression tests using Gleeble-1500 thermomechanical simulator at temperatures ranging from 350-500°C under strain rates of 0.01-10 s-1. The true stress-true strain curves were obtained in the tests. Constitutive equation and processing map were established. The results show that the flow stress decreases with the increase of deformation temperature at a constant strain rate, and increases with the increase of strain rate at constant temperature, indicating that composite is a positive strain rate sensitive material. The flow stress behavior of composite during hot compression deformation can be represented by a Zener-Hollomon parameter in the hyperbolic sine form. Its activation energy for hot deformation Q is 183.251 kJ/mol. The optimum hot working conditions for this material are suggested.

Abstract:

The unique property combination of Al/SiCp based composites make them very attractive for applications in automotive and aerospace industries. The choice of composite materials for these applications is directly influenced by their inherent properties which are a function of the processing route employed. Like other processing parameters, surface modification treatment of SiCp can play a major role in determining the properties of Al/SiCp composites. In this study, the effects of SiC reinforcement (wt%) fractions (SRF), surface oxidation temperature (SOT) and preheating temperature (PT) parameters on the wear and friction properties of stir-cast Al-SiCp based composite were investigated. Experimental data and models are generated and analyzed based on a three-factors-five-level central composite design (CCD) and analysis of variance (ANOVA). The empirical models developed for wear rate and coefficient of friction (COF) considering the pre-processing parameters adequately predicts the Al-SiCp properties with the silicon carbide reinforcement (wt%) fraction emerged as the most influencing factor. The goal of the optimization process is to minimize both wear rate and COF. For wear rate, SRF at 44.49 % contribution had the most influence on wear rate, while SOT and PT had 0.65 % and 1.03 % influence on wear rate respectively. For COF, SRF also showed highest influence of 35.48 % on COF, while SOT and PT had 0.047% and 2.66% influence on COF respectively. From the optimization analysis, the set of conditions that simultaneously optimizes both wear rate and COF are 10% SiC weight (SW), 1234°C surface oxidation temperature (SOT), and 376.2°C preheat temperature (PT). The resulting responses at this optimized condition are minimum wear rate of 0.11 mm3/m and COF of 0.11 with a confidence and desirability level of 1.

As the typical particle-reinforced aluminum matrix composite, SiCp/Al composite has low density, high elastic modulus and high thermal conductivity, and is one of the most competitive metal matrix composites. Grinding is the main processing technique of SiCp/Al composite, energy consumption of the grinding process provides guidance for the energy saving, which is the aim of green manufacturing. In this paper, grinding experiments were designed and conducted to obtain the energy consumption of the grinding machine tool. The Particle Swarm Optimization (PSO) BP neural network prediction model was applied in the energy consumption prediction model of SiCp/Al composite in grinding. It showed that the Particle Swarm Optimization (PSO) BP neural network prediction model has high prediction accuracy. The prediction model of energy consumption based on PSO-BP neural network is helpful in energy saving, which contributes to greening manufacturing.

Abstract:

SiC particle reinforced AlCu5Mn composite foams (SiCp/ZAlCu5Mn composite foams) were fabricated by the direct foaming of the melt. The quasi-static compressive properties of SiCp/ZAlCu5Mn composite foams were tested by compressive test. The effects of SiC particle, the average diameter of pores, and the relative density on the quasi-static compressive properties of SiCp/ZAlCu5Mn composite foams were performed with the universal material testing machine. The microstructure of SiCp/ZAlCu5Mn composite was studied by SEM. The results show that choosing small size of SiC particles as reinforced material, thinning pore diameter, and increasing the relative density of SiCp/ZAlCu5Mn composite foams with the same volume fraction of SiC particles can improve the energy absorption ability under the quasi-static loading. SiCp/ZAlCu5Mn composite foams are of well compressive property. The compressive deformation course of SiCp/ZAlCu5Mn composite foams involves three stages that are the linearly elastic deformation region, the collapse plateau region, and the densification region. The test results may be influenced by strain gauge, data processing method, shape of incident wave etc.

Abstract:

Thermal spray technology provides wear-resistant coating on the surface of mechanical components. In this study, wear characteristics of SiCp reinforced Al matrix composite coatings were evaluated. SiCp reinforced Al matrix composite coatings were fabricated using the mixed powders which have different fraction of the SiC reinforcement, 0, 20, 40 and 60 vol% on Al 6061 substrate by thermal spray process. Dry sliding wear tests were performed on these coatings using varied sliding speeds and applied loads. Wear behavior of these Al-based composite coatings were investigated using scanning electron microscope(SEM), energy dispersive X-ray spectroscopy(EDX) and X-ray diffraction(XRD). The composites coatings reinforced with 40 vol% of SiC particles showed the most excellent wear resistance. Although the wear rate increased according to the increase in the applied load, it decreased according to the increase in the sliding speed. The major wear behavior of the SiCp reinforced Al matrix composite coatings is transferred from the adhesive wear to the abrasive wear according to the increase in the sliding speed and the applied load. These results were significantly influenced by the formation of mechanical mixed layer(MML).

Experimental results showed that when the size of SiC particle decreased, the tensile properties of the composite increased. The tensile properties of SiCp/AZ91 composite with small particles are controlled by the properties of matrix alloy and the strength of the interface between the matrix and reinforcements, but the composites reinforced by large particles are controlled by the fracture of the particles.
