ABSTRACT Magnesium is the third most commonly used structural metal, following iron and aluminium. It has always been called the lightest useful metal that can be alloyed with other metals to be used for different applications. The opportunity of magnesium alloys exists in a wide variety of industrial applications such as frames and materials of automobiles and aircrafts. Massive potential is expected in aerospace applications and military sectors. As the desire to further utilize lightweight magnesium alloys in various industrial applications grows, different aspects of magnesium research must be intensified in order to improve various properties of magnesium alloys and enhance their chances of being selected by product designers. In order to effectively harness the usefulness of magnesium alloys in different structural parts (vehicle body, chassis, fuselage of plane etc.), we must have a clear understanding of their performance under impact where deformation occurs under a broad range of strain rate and temperature. In current research, detailed experimental study followed by the microstructural analysis has been carried out to investigate the high strain rate behaviors of alloy AZ31B and Stainless Steel 316 regarding their potentials to be used in different structural and armory parts.
