Microstructural Characterization and Hardness Properties of Magnesium Alloy Processed by High Pressure Torsion

Abstract
Magnesium and magnesium alloys are the lightest of all metal used for structural construction. This property of magnesium made it to be the most used material in the automobile manufacturing industries and in aerospace as well as in other industries. This research is based on the process improvement of pure commensally magnesium alloy (Mg 99.94%) using high pressure torsion (HPT) process. The investigation was based on the measurement of hardness properties and microstructural characterization of magnesium alloy processed by high pressure torsion (HPT).
