介绍了高应变率载荷条件下镁合金的吸能特性及变形特征；论述了对镁合金抗弹性能有重要影响的动态强度、高应变率能量吸收率、高应变率变形断裂特征和动态强度等科学问题；就镁合金在装甲领域的应用研究做了初步探讨。

The absorbed energy property and deformation characteristic of magnesium alloy under high strain rate loading are described. Then the basic science problem connected with materials' ballistic performance closely such as dynamic strength, absorbed energy rate, adiabatic shear deformation localization and dynamic hardness are discussed primarily. The purpose of the paper is that promoting the basic and application research of armor magnesium alloys.
