研究了MgLi4Al 和MgLi8Al合金的阻尼性能。结果表明, Mg-Li-Al合金的阻尼性能随锂含量的增多和温度的提高而明显增高。其中MgLi8Al合金的室温阻尼性能达到Q-1=0.01的高阻尼值。MgLi8Al合金的阻尼明显大于MgLi4Al合金的阻尼是由于MgLi8Al合金相界阻尼的贡献。
The damping capacity of MgLi4Al and MgLi8Al alloys was studied. The results showed that the damping capacity of Mg-Li-Al alloys increases with the temperature and lithium content. For MgLi8Al alloy as an example, the damping capacity go up to Q-1= 0.01, in the range of high damping metallic materials. The higher damping capacity of MgLi8Al alloy may be attributed to the interface damping between α(Mg) and β(Li) phases.
