Post deformation analysis of the ballistic impacted magnesium alloys, a short-review

Abstract

From the mechanistic point of view, magnesium alloys are lightweight materials and are receiving increasing attention in the past several years in various fields. Prof. Liang Zhen from Harbin Institute of Technology, China and the United State military are showing keen interest in the development of magnesium alloys as ballistic resistant material. However, their use is still limited owing to low ductility, low formability, and average mechanical properties. The magnesium alloys components must withstand the shockwave under hypervelocity ballistic impact. The ballistic testing can produce gradient variations of the strain and stress-energy away from the crater, and useful for the development of these alloys in the military and aerospace industry. Therefore, the present review article shed light on the post deformation analysis of the Mg alloys subjected to the different projectiles under ballistic impact, and the underlying mechanisms were discussed. In the end, some important issues regarding the ballistic impact and further studies in this field were proposed.
