A Review of the Anomalous Dynamic Behavior in Magnesium Alloys

A material’s ability to withstand high deformation rates without failure has a profound effect on many applications. Indeed, in modern industrial society, e.g., alternative energy sources (fusion reactors), automobile crashes, projectile impact, and deep-space exploration (meteoroid impact), structural metals often experience deformation rates of 10³–10⁴ s⁻¹ or higher, which can lead to catastrophic failures due to loss in ductility. However, the effects of stress state combined with high strain-rate behavior on deformation mechanisms are still not fully explored. Therefore, this paper attempts to lay out a perspective of anomalous dynamic behavior observed in low-melting-temperature materials such as magnesium (Mg)-based alloys. In other words, the paper reviews research conducted on time-dependent dynamic behavior along with the multiaxial state of stress in Mg alloys.
