摘要
对用稀土Ｃｅ 改性的高阻尼ＭｎＣｕ 合金的阻尼性能与微观组织进行了研究。结果表明，添加稀土元素Ｃｅ，不仅能显著提高ＭｎＣｕ 合金的阻尼性能，而且能缩短达到峰值阻尼性能的时效时间，同时还抑制了过时效时阻尼性能的下降。
In this paper, the damping capacity and microstructure of Ce modified Mn Cu alloy are investigated. The results show that the addition of RE Ce can considerably increase the damping capacity of the aged Mn Cu alloy and shorten the ageing time taken to reach the peak damping and retard the loss of the damping capacity when the alloy over aged.
