Mechanical and Wear Properties of Al/TiC Composites Fabricated via Combined Compo-Casting and APB Process

Blog Article

One of the popular techniques to fabricate metal matrix composites is the compo-casting process.The un-uniform spreading of reinforced subdivisions (particles) inside the metallic matrix and the lack of desirable mechanical properties of the final produced composites due to the low bonding strength among the metal matrix and reinforcement particles are the main challenges in this process.The warm accumulative press bonding (APB) technique was utilized as the supplementary technique to improve the mechanical and microstructural evolution of casted Al/TiC composite here bars to remove these difficulties.So, using the tensile test, average Vickers micro hardness test, wear test and scanning electron microscopy transpharm online shopping (SEM), the microstructure evolution and mechanical properties of these composites have been considered vs.

various WAPB steps.The SEM morphology of samples revealed that big titanium carbide clusters are broken and make a uniform distribution of titanium carbide particles at higher APB steps.It was shown that the cumulative forming steps of the APB process improved the mechanical properties of composites.In general, combining the compo-casting and APB process would result in making Al/TiC composites with high uniformity and good mechanical and microstructural properties.
