Development Comparisons of Al-Sic MMC using Stir Casting Process and Powder Metallurgy Process for Automotive Industries

Material selections for automotive industries are the very important role in the recent era. Presently used materials have some limitation like easily worn out, higher weight-to-strength ratio and life of components are shorter. To overcome this problem, we developed an Aluminium Silicon Carbide composite material which has a higher wear resistance, the higher strength-to-weight ratio that can be satisfied the requirement of automotive industries. First of all, we developed an Aluminium Silicon Carbide metal matrix composite using a stir casting process. Improving the mechanical properties of composite material, Silicon carbide is used as reinforcement in Aluminium matrix by varying the percentage of Silicon Carbide weight fraction (15, 20 and 30%). Secondly, development of Aluminium Silicon Carbide by powder metallurgy process with same Silicon Carbide percentage in Aluminium matrix. Developed Aluminium Silicon Carbide composite material properties have been checked by microstructure examination, strength and hardness and compared the developed Aluminium Silicon Carbide metal matrix composite materials properties by stir casting process and powder metallurgy process.
