摘要
介绍了强应变塑性大变形下镁合金研究现状。重点综述了在较高应变率及冲击载荷作用下关于镁合金变形的研究情况,同时也比较详细地综述了在不同温度、不同载荷作用下镁合金塑性变形特征及其物理机制。最后简要介绍了几个描述材料在较高应变率和冲击载荷作用下变形行为的数学表示式,并就镁合金作为结构材料的研究说明了作者的一些看法。
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.
