An Overview on Synthesis of Magnesium Alloy based Metal Matrix Composites

Magnesium alloy based composites are viewed as potential candidates for various applications in automobile, aerospace and defense sectors. Magnesium alloys majorly consisting of magnesium with fractional quantities of aluminium, zinc and manganese, are popularly used in light weight applications. This alloy can be reinforced with many of the ceramic oxides such as silicon nitride (Si3N4), titanium carbide (TiC) etc. in various forms to improve its mechanical and tribological properties. Currently many researchers are exploring the possibilities of synthesizing magnesium through several techniques. This paper study presents an overview of various synthesizing techniques of magnesium alloy based composites using ceramic reinforcements. An attempt is also made to summarize the effect of heat treatment on above said composites.
