Abstract: Increase in industrial requirements focusing on various research activities on composite material in a narrow region. This is being observed through replacement of material components over an existing one due to its betterment in structure behaviour and properties. In recent days, nano technology comes to play an essential part in composites and coating of material to upgradation of parameters. This work constitute the outlines and importance of extrusion process in magnesium matrix nano composites, meanwhile the effect of various factors like temperature, grain size, extrusion speed, extrusion ratio etc., on enhancing the microstructure and mechanical properties of the magnesium matrix composites. The extruded components have more excellent properties such as tensile strength, proof stress and elongation than the cast components. Addition of nano particles may lead to significant inhibition in grain boundaries resulting in refined grains after extrusion resulting in high strength of the composites. Nano particles can significantly increase the mechanical strength of magnesium matrix by effectively promoting particle hardening mechanism than micro size particles.

Keywords: magnesium matrix nano composites; nano particles; extrusion process; dynamically re-crystallised grains.
