Abstract

Metal Matrix Composites (MMCs) are emerging as vital engineering materials due to their specific strength, ductility, toughness etc. As the demand for high specific strength materials is increasing day by day, Aluminium matrix can be strengthened by reinforcing with hard ceramic particles like Silicon Carbide (SiC), Aluminium Oxide (Al2O3) etc. In the present study, aluminium metal matrix composites were made by reinforcing with SiC and Al O particles using stir casting route. The mechanical properties such as hardness, strength, density, electrical conductivity and chemical analysis of the unreinforced Al and Al+15% SiC/ Al+15% Al2O3 / Al+10% SiC+5% Al2O3 (wt%) reinforced composites were examined. The micro structural characterization of the composites was studied with metallurgical microscope. It was observed that the hardness and compressive strength were increased, where as the density and elongation were decreased with the reinforcement in base aluminium composite.
