Experimental Research on the Tribological -Mechanical Properties of Al-SiC composites and EN31 Steel

Abstract

In this research, metal matrix composites was fabricated using stir cast technique. Al 6061 alloy (Matrix) and silicon carbide (Reinforcement) were selected as particles. Tata Ace (mini truck) frame made of EN31 steel considered as a comparative material. Optimal weight % of SiC particles was selected as 30 %. Tensile, impact, hardness tests and tribological behaviour of the fabricated composites and EN31 steel was carried out. The mechanical tests such as tensile, impact and hardness are conducted according to the ASTM standards. The results shows that the fabricated composites had improved properties when compared to EN31 steel.
