Abstract: Magnesium matrix composites are potential materials for various applications of aerospace and defense organizations 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 to the conventional engineering materials. This report presents an overview on the effects of different reinforcements in the magnesium and its alloy, so as to improve their mechanical and metallurgical properties. The morphology of microstructure and its effect on the physical properties of the magnesium is also discussed here. The micrograph showed that there was distribution of Boron carbide, Titanium carbide (TiC) and Carbon nanotubes (CNT) throughout the matrix. These nano particles were strengthening the magnesium nano novel composite through dispersion strengthening. Moreover, from the results, we understood that there was a considerable improvement in the tensile strength and hardness compared to the parent material.
