Abstract:
The widespread adoption of particulate metal matrix composites (MMCs) for engineering applications has been hindered by the high cost of producing components of complex shape. Casting technology may be the key to overcoming this problem with stir casting. But the problem arises with stir casting is wettability and porosity. To overcome the problem of porosity a hybrid casting process is needed. So, hybrid stir casting process was developed to produce a silicon carbide particulate aluminum alloy composite. In this paper, the authors have discussed the various parts like Muffle Furnace, Thermocouple, Electric motor Impeller & Stirrer, Crucible, Vacuum pump, Nitrogen gas, and Lifting mechanism of the Hybrid Stir Casting process.

Abstract:
Aluminium based composites exhibit many attractive material properties such as increased stiffness, wear resistance, specific strength and vibration damping and decreased co-efficient of thermal expansion compared with the conventional aluminium alloys. Aluminium Matrix Composites consist of non-metallic reinforcement which offers advantageous properties over base material. Reinforcements like SiC, B4C and Al2O3 are normally preferred to improve the mechanical properties. Here Aluminum LM25 is selected as matrix material while Silicon carbide and Boron carbide are selected as reinforcement material. The fabrication of aluminium matrix was done by stir casting method. In the present study an attempt has been made to investigate the effect of three major stir casting parameters (stir speed, stir duration and preheated temperature of reinforcement material) on stir casting of Aluminium LM25 - SiC - B4C composite. Experiments were conducted based on Taguchi methodology. Taguchi quality design concepts of L9 orthogonal array has been used to determine S/N ratio and through S/N ratio a set of optimum stir casting parameters were obtained. The experimental results confirmed the validity of Taguchi method for enhancing tensile strength of castings.

Abstract:
AbstractMetal is the one of the important material in engineering materials because of their high strength to weight ratio. However the pure metals cannot be used as engineering materials due to their ductile property. So, to improve their mechanical properties, some of the high strength materials (not metals) were added as reinforcement to improve the mechanical properties of pure metals and the newly developed material is called as metal matrix composites. At present, Aluminium, Copper, Magnesium, Titanium and Iron have been used as matrix materials and materials like TiC, SiC, B4C, WC, Cr3 C, TiO2, ZrO2, Gr, MoS2 and Si3N4 have been used as reinforcements. There are many processing techniques to fabricate metal matrix composites namely stir casting, ultra-sonic assisted casting, compo-casting, rheo casting, powder metallurgy technique, etc,. Among these, stir casting process is the most suitable and economical method to fabricate the metal matrix composites. In this article, an effort has been made to review the work of various researchers to fabricate metal matrix composites through stir casting process.

Abstract:
Aluminum matrix composites are widely employed in aerospace, military, automobile, and transport applications. The high-strength with low-weight materials are required to fulfill the requirement of high-performance applications. The low-weight materials are reinforced with hard reinforcements to obtain high-strength-to-weight properties for using high-performance applications. The process parameters of fabrication technique define the mechanical and tribological properties. Many types of optimization tools are used for optimizing the process parameters of fabrication method. In this research, the aluminum alloy 7050 and boron carbide are selected as matrix material and reinforcement material. The fabrication of Al7050/B4C composites is produced by the stir casting method. The optimization on stir casting process parameters is done by using the Taguchi approach. The L9 orthogonal array is chosen for this investigation. The chosen input stir casting process parameters are wt% B4C, stirring time (10, 15, and 20 min), stirring speed (300, 350, and 400 rpm), and melting temperature (700, 750, and 800°C). The microhardness is selected as a valuable response parameter for optimizing the stir casting process parameters. The influencing stir casting process parameter sequence is determined by using mean table. The influencing parameters of stir casting on microhardness are stirring speed, stirring time, wt% B4C, and melting temperature. The 9 wt% of boron carbide addition increases the microhardness, and it is higher than the other wt%. The optimum combination of input process parameter combination is 9 wt% boron carbide, 750°C melting temperature, 350 rpm stirring speed, and 15 min stirring time (A3B2C2D2). The percentage of microhardness value improvement is 20.3%.

Abstract:
Lightweight materials are extremely needed for the manufacturing of industrial parts and are used in aerospace, automobile body shops, biomedical instruments, etc. Aluminium alloy is one of the light-weight materials, and it fulfills the industrial demands based on their natural strength/stiffness, enhanced temperature permanence, superior wear, and corrosion resistance. This experimental work considered aluminium alloy (AA8014) with reinforced particles of silicon nitride (Si3N4) and zirconium dioxide (ZrO2) for preparing aluminium hybrid composites. Hybrid composites are prepared by a stir casting process involving different process parameters. L27 orthogonal array is used for optimizing the stir casting parameters with the assistance of the statistical Taguchi approach. Stir casting parameters are the percentage of reinforcement (4%, 6%, and 8%), stir speed (400 rpm, 500 rpm, and 600 rpm), stir time (20 min, 25 min, and 30 min), and molten temperature (700 oC, 800 oC, and 900 oC). Mechanical performance such as wear and microhardness of the hybrid composites is evaluated. Minimum wear and higher microhardness are encountered at a percentage of reinforcement = 6%, stir speed = 400 rpm, stir time = 30 min, and molten temperature = 900°C. In wear analysis, the percentage of reinforcement highly influences the wear properties (7.06% contribution). In microhardness analysis, molten temperature parameter is the extreme influencer (11.15% contribution).

Abstract:
Ingeniero Civil Mecánico
El aluminio y sus aleaciones son materiales con una elevada demanda en los campos industrial, aeroespacial y automotriz, debido a su amplia variedad de propiedades mecánicas y sobre todo por su elevada proporción de resistencia-peso, y gran resistencia a la corrosión. Para mejorar aún más las propiedades de estos materiales, se han creado los materiales compuestos de matriz metálica, los cuales tienen excelentes propiedades mecánicas y por lo tanto motiva su investigación. El objetivo general de este trabajo es estudiar el efecto de la cantidad de refuerzo de 〖Al〗_2 O_(3 ) sobre el creep y módulo elástico, en una matriz de aluminio 6061. También, se busca medir los términos del exponente del esfuerzo (n) y la energía de activación (Q) de la ecuación fundamental del creep. Para llevar esto acabo, se tienen muestras del compuesto con distintos porcentajes de 〖Al〗_2 O_3 como refuerzo. Luego, se implementa la técnica de creep por impresión con el fin de aprovechar las ventajas de este en comparación al creep por compresión. Las ventajas radican principalmente en la optimización del uso del material y en la disminución de error en los resultados. Se realizan análisis de vibraciones mediante excitación por impulso. A continuación, se realizan tratamientos térmicos de endurecimiento por solución y envejecimiento, y en paralelo se hacen mediciones de dureza Vickers después de cada uno de estos tratamientos. Se realizan ensayos de creep a temperaturas entre los 220°C y 280°C a diferentes esfuerzos constantes, para obtener varias curvas características de estas y mejorar el análisis de las mismas. Los resultados muestran que el refuerzo de alúmina aumenta el módulo de elasticidad de estas, obteniéndose valores cercanos a los 63 [GPa]. No se comprueba una relación lineal directa entre la cantidad de refuerzo con la deformación en creep y módulo elástico. Se incorpora el término de umbral de tensión que ayuda a explicar los mecanismos de creep existentes en los MMC de forma análoga a las aleaciones sólidas. Finalmente en los ensayos de creep, las muestras se comportan como si fuesen aleaciones de solución sólida. No se encuentra un valor certero para n ni Q debido a errores en mediciones, pero se logra ver una leve tendencia del mecanismo de creep por deslizamiento viscoso de dislocaciones.

Abstract:
In recent years, the developments of metal matrix composite (MMCs) have been receiving worldwide attention on account of their superior strength and stiffness. They also have high wear resistance and creep resistance in comparison to their corresponding wrought alloys. The existing process to fabricate, characterize and machine this special material needs improvement. Although, some attempts have been made to machine these materials but no suggestion has been made so far about the optimum value of cutting parameters for a particular type of MMC. Optimum value of cutting parameters will be different for different MMCs. Some categories of these MMC find applications in aircraft and space industries, where precise machining is most important. Hence, there is a need to develop a process for precise, energy efficient and cost effective machining. So that Aluminium composites for light weight applications can be fabricated cost effectively. So this study is aimed at low cost fabrication of Aluminium metal matrix composite with Boron carbide (B4C) as dispersed phase and AA7075 as matrix phase which can be used in various light weight applications by using ‘Stir Casting’ method. The developed composite shows improved tensile and yield strength along with increase in vicker’s hardness. The microstructure studies have also been carried out which uniform distribution of reinforcement particles, phases made after development of composite and also the reduction in grain size. The wear test was also done which revealed favorable results. Further optimization of machining results has been done for studying the effect of speed, feed and depth of cut. The results have been compared with the results of as-casted AA7075.

Abstract:
Microstructural and mechanical data from the literature of friction stir processed (FSPed) cast aluminum alloys were reanalyzed. Results indicated that friction stir processing (FSP) produced more homogeneous microstructures, with finer eutectic Si particles, grains, and intermetallics. However, a relationship between microstructural measures and process parameters could not be established. Regardless of the resultant microstructure, structural casting defects, i.e., pores and oxide films, were reduced in size or completely eliminated after FSP. Consequently, ductility and fatigue life were drastically improved by FSP. Quality index analysis showed that some FSPed specimens have a higher structural quality than aerospace and premium quality castings, and can be used to determine the intrinsic properties of cast aluminum alloys.

Abstract:
This unit deals with the selection and fabrication of HMMC (Al6063-10SiC-5B4C-Mg) constituents by extensive biography review and satisfactory fabrication design. Researchers have promoted an extensive collection of Al6063 composites employing organic and inorganic reinforcements. The fundamental purpose of the broken-up stages is to constrain the metal matrix in a relevant capacity to strengthen the properties of the base materials. In the case of Al6063, the reinforcement weighty subject matter in the composite varies from 5 wt.% to 30 wt.%. Diverse classes of reinforcements had sought to integrate and operate in the composite formulation as hybrid reinforcements. This chapter further discusses the comprehensive development stages of 84% wt of Al 6063, 10% wt of SiC, 5% wt of B4C with 1% wt of Mg hybrid metal matrix composite (HMMC) through the stir casting approach. During the stir casting process, the melting action of the material emanates numerous gases and residuals apart from the expected composite. The residuals have numerous environmental concerns, which require discussion since some of the vapors and substantial waste can lead to detrimental effects on the environment in terms of air and soil pollution.

Abstract:
Abstract In this work, conventional Friction Stir Welding (FSW) was used to investigate the weldability of recycled hybrid Aluminum Matrix Composites (AMCs). The novel composites were developed by squeeze stir casting process of scrap aluminum alloy wheels of cars as matrix and 4 wt.% of graphite, and 5 wt% of alumina as reinforcements. The casting parameters optimized from our previous work, such as squeeze pressure of 100 MPa, squeeze time of 45s, die preheating temperature of 250°C, and stirrer speed of 525 rpm, were used while casting the hybrid AMC rods. 4 mm plates were cut from each rod and subjected to an in-air friction stir welding process using a cylindrical tool of 16 mm diameter and 3 mm pin depth. Two-pass welding with a tool rotation of 1600 rpm and feed rates of 24 mm/min and 55 mm/min were used for FSW of samples. The welded section was cut out and subjected to mechanical tests such as tensile and Brinell hardness tests. It was observed that the samples welded at lower feed rates exhibited a higher tensile strength of 154 MPa and Brinell Hardness number of 61. The weldability of the recycled composites was successfully tested using FSW, a sustainable welding process. The work shows that hybrid recycled AMCs can be used for piping’s and structures prone to wear.

Abstract:
Abstract In the present study, four AA7075 composite samples reinforced with varying amounts of TaC in the range of 0.1wt%, 0.2wt%, 0.3wt%, 0.4wt%, were developed using a multi-step stir casting to improve the mechanical properties. The mechanical properties of the developed samples such as microhardness, tensile strength, compression strength, and elongation were characterized using a computerized Vickers hardness testing machine for microhardness and a Universal Testing Machine for both tensile and compression respectively. The effect of Tantalum carbide on the microstructures of the composite samples was characterized using an optical microscope. The microstructures and the mechanical properties of the developed composites were correlated. The results show a gradual increase in the mechanical properties with an increase in TaC reinforcement, However, the elongation decreased gradually with the increase in TaC content. The highest mechanical properties were found in the composite reinforced with 0.4. wt% TaC with the highest microhardness of 121 Hv, Ultimate Tensile Strength of 369 MPa, Yield Strength of 338 MPa and compression strength of 784 MPa.

Abstract:
Composite materials are important engineering materials due to their outstanding mechanical properties. Composite materials offer superior properties to conventional alloys for various applications as they have high stiffness, strength and wear resistance. The high cost and difficulty of processing these composites restricted their application and led to the development of reinforced composites. In the last two decades, wear studies on Particulate Metal Matrix Composites (PMMCs) reinforced with various reinforcements ranging from very soft materials like graphite, talc etc., to high hardened ceramic particulates like SiCp, Al2O3 etc., have been reported to be superior to their respective unreinforced alloys. Therefore, present work focused on the study of machinability of Al based binary composites reinforced with 8.5% SiC and Al based Hybrid composite reinforced with 8.5% SiC, 2% and 4% Graphite powder (Solid lubricant) have been studied by considering the effect of process parameters such as speed, feed, depth of cut and composition of material. Binary and hybrid composite materials have been casted by stir casting methodology. Experiments have been conducted using Design of Experiments approach to reduce the number of experiments and time. The cutting force and surface roughness in turning of both the binary and hybrid materials have been measured using cutting force dynamometer (4 component kistler dynamometer) and the roughness has been measured using surface roughness tester (Marsurf M400) simultaneously. The multi objective optimization has been carried out using Grey relational based Taguchi method. It was observed that feed was the most influencing factor compared to others factors and also results shown that the performance characteristics cutting force and the surface roughness are greatly enhanced by using Grey relational Analysis.
