The Properties of an Aluminium Metal Matrix Composites: A Review

Abstract

Now a days aluminium matrix composites setting a trend in its usage in various sectors especially in the areas of space, automobile, marine applications due to its less density as well as improved mechanical and tribological properties. The usage of aluminium is restricted due to its limited strength and hardness. In order to improve those properties aluminium is added with other elements, one such popular example is the aluminium metal matrix composites. There is a significant improvement in strength, hardness, wear resistance, creep and fatigue properties of aluminium matrix with the addition of various reinforcements. An attempt has been made to summarize the effect of various reinforcements on aluminium matrix on mechanical and tribological properties which are processed under various casting techniques. This paper presents the overview of the effect of addition on different reinforcements in aluminium alloy highlighting their merits and demerits.
