Abstract

Magnesium alloys have extensive application in industries. The range of physical properties that can be imparted to them is remarkable. Magnesium–Aluminium binary alloys generally possess good castability and good mechanical properties. The objective of the present investigation is to study the effect of varying weight percentage of alumina (Al2O3) on the hardness and wear resistance of the Mg–Al alloy. The addition of alumina resulted in a considerable increase in the Vicker's microhardness number and wear resistance of the original alloy. Wear resistance and Vicker's microhardness number increase with the increasing proportion of alumina powder addition because of the deposition of crystalline alumina granules on the border and in the phases of remnant alloy during freezing process.
