Abstract

Al-Cu-Mg alloy and its matrix composites reinforced with different volume fractions of sub-micron silicon carbide particles have been produced in powder metallurgy route. The effects of silicon carbon particles and mechanical alloying (MA) technology on the mechanical and tribological properties were investigated. The results show that the composites have better mechanical and tribological properties than the matrix alloy, and the 9vol%SiCp/Al-Cu-Mg composite has the best performances. Mechanical alloying (MA) technology further improves the hardness and tensile strength, hardly influences the wear rate of the 9vol%SiCp/Al-Cu-Mg composite but somewhat affects its friction coefficient.
