Research progress in influence of alloying elements on damping properties of magnesium alloys

简介镁合金的阻尼机理,在室温下主要为位错阻尼,在高温下除位错阻尼外还有晶界阻尼的贡献。综述合金元素对镁合金阻尼性能影响的研究现状,并展望阻尼镁合金材料的应用前景。指出通过引入新的阻尼机制或综合发挥多种阻尼机制的优点,获得兼具高强度高阻尼的结构功能一体化材料,将是未来高阻尼镁合金材料研究的重要方向。

The damping mechanism of magnesium alloy was briefly introduced. Dislocation damping is the main mechanism at room temperature, but under high temperature, besides dislocation damping, there is also crystal interface damping. The research status in influence of alloying elements on the damping properties of magnesium alloy was also discussed. And the future application of damping magnesium alloy materials was prospected. It was pointed out that by introducing new damping mechanisms or using the advantages of many damping mechanisms, the structure-function integration materials with high strength and high-damping property could be obtained, and it would be the important research direction of high-damping magnesium alloy materials in the future.
