对比研究了 ZM5镁合金及其 Gr/ Mg复合材料的室温和高温阻尼行为 ,发现它们的阻尼行为相似 ,但镁基复合材料阻尼性能无论在室温还是在高温下都优于镁合金 ,并随温度升高 ,这种提高的效果更大。研究认为镁基复合材料的主要阻尼机制是室温的位错阻尼和高温的界面阻尼。
The damping behaviors of ZM5 magnesium alloy and its Gr / Mg composite at room temperature and high temperature were compared and studied. The damping behavior of ZM5 magnesium alloy and its Gr / Mg composite was better than that of magnesium alloy both at room temperature and at high temperature. Increase, this increase is more effective. It is considered that the main damping mechanisms of Mg-based composites are dislocation damping at room temperature and high temperature interface damping.
