Deep drawing of magnesium alloys: A review

Abstract

Magnesium alloy, the lightest structural metal substance currently known, has garnered a great deal of interest in recent times. Magnesium alloys not only offer high specific strength, high specific stiffness, and low density, but they also have outstanding anti-electromagnetic interference properties, shock absorption, are easy to recycle, and are biocompatible. It has a wide range of uses, including automotive, aerospace, military, and biological. Magnesium alloy's compact hexagonal structure creates few slip systems at room temperature, leading to low plasticity and limited applicability. Deep drawing of magnesium alloys is a major procedure in the aerospace and automotive sectors due to the high strength-to-weight ratio. This paper presents all the aspects of deep drawing of magnesium alloys, covering the innovative methods of deep drawing, factors influencing the performance of deep drawing, simulation and modeling, optimization of deep drawing, and the microstructural changes during deep drawing and its impact on mechanical properties. Finally, the challenges and scope for future research are explored.
