| 摘 要： | 介绍了镁合金的阻尼机理,在常温下其阻尼机制主要是位错机制,在高温条件下,由于晶界也参与滑移,所以除了位错阻尼外还有晶界阻尼的贡献。着重介绍了Mg-Al系、Mg-Zr系、Mg-Li系、Mg-RE系以及镁基复合材料的阻尼特性．讲述了热处理工艺对镁合金阻尼性能及其力学性能的影响。

| Abstract: | The damping mechanism of magnesium alloy was introduced,which is belongs to dislocation damping mechanism under the room temperature.But under high temperature,besides dislocation damping,there is also crystal interface damping.The damping capacity of Mg-Al,Mg-Zr,Mg-Li,Mg-RE and magnesium matrix composits were recommended,and the influence of heat treatment on the damping and mechanics property of magnesium alloy was expounded. |
