This study aims to investigate on the effects of alloying elements and heat treatment on the microstructures, wear and heat resistance of Al-Si-Cu-Mg-(Ni)/SiCp prepared by the duplex process developed in previous study, which consists of squeeze infiltration (1st process) and squeeze casting (2nd process). The hardness of composite increased with decrease in SiCp size and Ni addition in both the heat exposured composite and the as-cast one. And the heat and wear resisting properties was improved by the SiCp reinforcement and the Ni addition. The wear amount of Al/SiCp composite decreased with decreasing in the size of silicon carbide particle.
