Material Characterization Study on Aluminium Metal Matrix Composites by Enhanced Stir Casting Method
Metal Matrix Composites possesses high mechanical properties compared to unreinforced materials. Aluminium Matrix Composites (AMC) is attracted in the emerging world because of its low cost, less weight and enhanced mechanical properties. In the present study the enhancement in mechanical properties like hardness and tensile strength of AMCs by reinforcing AA 6061 matrix with silicon carbide (SiC) and boron carbide (B4C) particles are analyzed. By enhanced stir casting method aluminium matrix was reinforced with boron carbide particulates and silicon carbide particulates with the various weight percentage of 2.5 %,5% and 7.5%.The tensile strength and hardness was found to increase with the increase in wt% of the reinforcement. From the analysis it is observed that the mechanical property of B4C reinforced AMC is significantly good compared to SiC reinforced AMC.
