Dynamic mechanical behavior of magnesium alloys: A review

Light-weight magnesium alloys have great potential to be used in various fields due to their excellent combination of physical and mechanical properties. In crystals, hexagonal metals are distinct from cubic metals because they have a smaller number of slip systems and twinning activity. Sudden impact under a high strain rate causes complex deformation in magnesium alloys and limits their widespread use in defense and industrial applications. Complex deformation is also attributed to the initial processing history of the magnesium alloys. To systematically explain this complex dynamic behavior, this review focuses on the micro-structural evolution of Mg alloys that were subjected to high strain rate compression. Moreover, unresolved problems and future targets are discussed in the \conclusion" section to more effectively understand the complex deformation behavior of Mg alloys described in this paper.
