Review of Recent Studies in Magnesium Matrix Composites and their Fabrication Techniques

Magnesium matrix composites are very attractive materials for various applications of aerospace, defence organizations and automotive industry due to their low density, good mechanical and physical properties. The improvement of specific strength, stiffness, damping behaviour, wear behaviour, creep and fatigue properties are significantly influenced by the addition of reinforcing elements into the metallic matrix compared with the conventional engineering materials. This article represents different types of reinforcements and their effect on mechanical and physical properties magnesium and its alloy. Emphasis is also made on various fabrication techniques like friction stir casting, vacuum stir casting, Squeeze casting, Powder metallurgy, In-situ synthesis, Mechanical alloying and Pressureless infiltration. Most important applications of diverse magnesium MMCs are also examined critically in this work.
