Abstract :
Alloy AZ91D is a leading magnesium alloy used for structural and transport applications. It contains aluminium and zinc as main alloying elements. This work involves a metal matrix composite (MMC) been fabricated using Mg AZ91D alloy and TiC as reinforcement. Wear resistance were evaluated under dry sliding condition at different loads. Wear mechanisms of the composite are basically abrasion-adhesion. The wear resistance of the composite Mg AZ91D/TiC was better than AZ91D Mg alloy. Mechanical property characterization of the composite material revealed an increase in modulus, yield strength and ultimate strength of the composite when compared to AZ91D Mg alloy.
