| Abstract: | Study about micro-structural changes of magnesium alloys under large strains and severe plastic deformation were introduced. Attention is concentrated on the research about the plastic deormation of magnesium alloys under impact loading and high strain rate. Meanwhile, the properties and physical mechanisms of plastic deformation of magnesium alloys under different loads and over a wide range of temperatures were reviewed. Finally, several formula for describing the behaviors of magnesium alloys under dynamic loading at high strain rate was summarized briefly, and some sugges-tions on the study of magnesium alloys used as structural materials were offered. |
| Keywords: | magnesium alloy large plastic deformation high strain rate impact loading |
