Abstract :
Usage of aluminium based metal matrix composite is unavoidable material for many engineering applications especially to weight – strength ratio needed. In this paper, the comparative study has been done for micro-structural and mechanical characteristics of Al6061 metal matrix reinforced with Silicon Carbide (SiC) and Aluminium Oxide (Al2O3) discretely. Test specimens were fabricated by adding 0, 5 and 10 wt % of SiC and Al2O3 in Al6061. Stir casting method used for the preparation of Al6061 composites. Morphology of the reinforcement particles and fabricated part was studied by SEM and Optical Microscope respectively, to analyze the distribution of particles in the Al6061 composite. Mechanical properties such as hardness, tensile and yield strength were carried out as per ASTM standards. The result proved that the density of composite is increases by increasing wt% of reinforcements in the matrix. The hardness value of SiC reinforced composite is higher than that of Al2O3 reinforced composite. Also the result shows that the maximum tensile strength at 5% wt of Al2O3 and SiC composite were identified.
