Abstract:
CNTs/AlN ceramics were fabricated by hot-pressing sintering process. The fracture toughness was measured by indentation method. The morphologies of indentation cracks were analyzed by SEM. The results show that the facture toughness of AlN was slightly improved because appreciate toughening mechanisms such as CNTs pull-out, crack bridging and deflect operate in CNTs/AlN. In addition, the facture toughness of CNTs/AlN increased with increasing CNTs content up to 3wt%. Then, the fracture toughness decrease when the CNTs content is 4wt%.

Abstract:
Al2O3/Ni composite ceramics toughened by metallic particles was fabricated by the vacuum reduction of Al2O3 and nickel nitrate (Ni(NO3)2•6H2O) mixed powders at 800-1000° for 2-4h and hot pressed at 1400° ~ 1500°C for 1-2h. Three-point bending strength and facture toughness of the composite were studied. With the increase of Ni content, its flexural strength and facture toughness increases significantly. Microstuctural investigations of the composite revealed that fine nickel particles dispersed homogeneously at the matrix grain boundaries, forming the intergranular nanocomposite.

Abstract:
Hierarchical analysis of the fracture toughness enhancement of carbon nanotube- (CNT-) reinforced hard matrix composites is carried out on the basis of shear-lag theory and facture mechanics. It is found that stronger CNT/matrix interfaces cannot definitely lead to the better fracture toughness of these composites, and the optimal interfacial chemical bond density is that making the failure mode just in the transition from CNT pull-out to CNT break. For hard matrix composites, the fracture toughness of composites with weak interfaces can be improved effectively by increasing the CNT length. However, for soft matrix composite, the fracture toughness improvement due to the reinforcing CNTs quickly becomes saturated with an increase in CNT length. The proposed theoretical model is also applicable to short fiber-reinforced composites.

Abstract:
Thermal barrier coating (TBC) is an essential requirement of a modern gas turbine engine. The TBC failure is the delamination and spallation. The oxidation damage under high temperature results in the reduction of interfacial adhesion. The interfacial fracture toughness is an important property to analyze the TBC failure. The interfacial fracture toughness of ceramic coating - bond coating has been researched in the past. However, the facture toughness of the bond coating - substrate due to the Al depletion was very few studied. In this study, a NiCrAlY bond coating by air plasma spray (APS) was deposited. The substrate was directionally solidified superalloy (DZ40M). Isothermal oxidation was performed at 10500 for 100h. Using the HXZ-1000 micro-hardness equipment, the five different times was chosen to test the hardness and the crack length, and then the fracture toughness was obtained. While the oxidation exposure time increased at 10500, the hardness of the substrate close to the bond coating decreased with the increase of the bond coating’ hardness. Meanwhile, the interfacial fracture toughness of the bond coating - substrate decreased because of the Al depletion.

Abstract:
Polymer nanocomposites (PNC) were prepared by in-situ polymerization technique. Rod shape alumina nanoparticles of two different sizes; i) having an average diameter in the range of 10 nm and length less than 50 nm and ii) having diameter in the range of 20-40 nm and length in the range of 200-400 nm; were selected as reinforcement material for epoxy matrix. PNCs having 0.5 %, 1 %, and 1.5 % weight fraction of alumina nanorods were prepared. Transmission electron micrographs (TEM) of the nanocomposites showed good dispersion of alumina nanoparticles in the epoxy. The quasi static plane strain fracture toughness of the PNCs was determined. Addition of both the types of alumina nanoparticles gives good improvement in the facture toughness of epoxy. An increment of 34% in fracture toughness was observed for composites having smaller size alumina nanorods at 1.5 wt.% over that of neat epoxy whereas fracture toughness was improved by 56 % for composites having alumina nanorods of higher aspect ratio at the same weight fraction. Scanning electron microscopic (SEM) images of the fracture surfaces were analyzed to investigate the mechanisms responsible for the increase in the fracture toughness of the PNCs.

Abstract:
The fracture behavior of Nb-based in-situ composites is reviewed to elucidate the effects of alloy additions on the fracture process in multiphase alloys. The overview paper summarizes the current understanding of the processes by which alloying addition and microstructure alter the near-tip deformation and fracture mechanism, and presents a methodology for predicting the fracture toughness of the constituent phases and the composite. The alloying effects observed in Nb-based in-situ composites can be attributed to changes in dislocation mobility in the metallic solid solution matrix that provides ductile phase toughening in the composites. The size, volume fraction, and the continuity of the intermetallic phases dictate the fracture path and impact significantly the facture toughness of the in-situ composites.

Full text
Abstract:
Multi-layer laminates were produced using alternating layers of Si3N4 and Si3N4+TiN. The differences in the coefficient of thermal expansions between the alternating layers lead to residual stresses after cooling. These are compressive in the Si3N4 layers and tensile in the Si3N4+TiN layers. The existence of these stresses in the laminates effect the crack propagation behaviour during failure. Different designs of laminates were produced with external layers under compression and tension exhibiting different failure mechanisms. Facture toughness was measured by SEVNB method. In systems with external layers under compression the measured fracture toughness was up to three times that of Si3N4, i.e. up to 17 MPa m1/2. In systems with external layers under tension during failure the energy absorbing effects of crack deflection and crack bifurcation were obtained. High temperature tests were performed to determine the onset temperature for residual stresses in these laminates. Micro-laminates with compressive layers of only 30 µm thickness with high strength and fracture toughness and were manufactured.

Abstract:
Mechanical properties of oil palm fruit bunch (OPFB) fibre composites have been quite extensively research by many researchers. However fracture toughness of this composite is still not fully understood. Hence this research used Sodium hydroxide (NaOH) at three different concentrations (1%, 3% and 5%) to treat the Oil palm fruit bunch (OPFB) fibre to investigate the effects of alkali treatment on the mechanical properties and facture toughness of OPFB fibre/epoxy composites. Tensile and fracture tests results indicate that the 3% NaOH concentration gave the best mechanical properties. An increase of 12% and 18% were observed for tensile and flexural moduli, meanwhile the increament of 9% was observed for tensile strength. However no increase on flexural strength was observed due to the OPFB treatment. Suggestion has been made to further study on the NaOH concentration in the range of 2% - 4%.

Abstract:
Ni/(ZrO2+Al2O3) nanocomposites have excellent mechanical properties, as well as self-healing function. The powder preparation was conducted by drying slurry consisting of distilled water, Al2O3, 3 mol % Y2O3doped ZrO2and nickel nitrate. After reduction at 600°C in a stream of Ar-1% H2, the powder mixture was consolidated by pulsed electric current sintering (PECS) at 1300°C for 5 min under 50 MPa. Surface cracks were generated by Vickers indentation on the polished surface of the test samples. Ni/(YZ+Al2O3) shows 1200 MPa in bending strength and 6.1 MPa m1/2in facture toughness. Crack-healing and oxidation tests were conducted at temperature ranging from 1100 to 1300°C in air. As a result, crack-disappearance occurred slightly faster than that of Ni/Al2O3.

Abstract:
The erosion wear resistance of YSZ ceramics is worth studying because solid particle erosion is one of the main causes of destroying the materials and apparatuses. In this paper, 8YSZ ceramics reinforced by NiCr alloy and Al2O3 particles were pressureless sintered at an optimized sintering condition. The facture toughness reached a maximum value of 4.6 MPa•m 1/2 when the addition of NiCr alloy is 12 vol.%, which was much higher than that of the pure 8YSZ ceramic (2.0 MPa•m 1/2) fabricated in the same condition. Solid particle erosion wear behavior of NiCr-Al2O3-ZrO2 (8Y) ceramics composites was performed by self-designed sand blasting type solid particle erosion wear equipment, using 36# SiC particles as abrasive particles with the 90o erosion angle. The effect of the volume addition of NiCr alloy on the erosion wear of NiCr-Al2O3-ZrO2 (8Y) ceramic composites at room temperature was investigated. The results show that the volume erosion rate of the ceramic composites decreased as the volume addition of the NiCr alloy increasing. Crossing cracks, plastic deformation and minor chipping are the major erosion mechanisms.

Abstract:
AbstractPhysical properties, and the friction and wear are important issues in small-scale applications, it is therefore essential that the materials used have good micromechanical and tribological properties. The adhesion, fracture toughness and wear properties of AlN-TiN thin composite films is being investigated in this study. The multilayered structures are generated using Pulsed Laser Deposition (PLD). The durability and functionality of thin films is subject to the adhesion between the coating and the underlying substrate in addition to it's resistance to cracking. The magnitude of the critical load during a scratch test is related to the adhesion of the substrate to the coating. In this test a Berkovich indenter is used for measurements and is drawn across the surface of a coating under an increasing load. The magnitude of the critical load will be studied for various films from a monolayer TiN film to different AlN-TiN films and those relative results compared to their facture toughness and their wear properties. Despite the adhesion, the critical load depends on several other parameters including the friction coefficient. The critical characteristic load is shown to depend on the number of layers and the relative AlN-TiN thickness. The fracture toughness showed a weak dependence on the layer characteristics.
