Abstract

Aluminum alloy AA-SiC and AA-Al2O3 composites with 3, 6 & 9 weight% of SiC and Al2O3 with average of 10 μm particle size are fabricated through powder metallurgy. The density, Rockwell hardness, Compressive strength and tribological behavior of composites were found to be improved. AA 2024 with 6% Al2O3 reinforced MMC's samples were exhibiting improved hardness results, strength behavior and stress-strain behavior when the samples are microwave sintered. AA 2900 with 6 wt% Al2O3 exhibited good ductility and formability properties closer to AA 2024. AA 2900 with 6 wt% Al2O3 displayed better frictional coefficient behavior compared to AA 2024.
