摘　　要：利用金相显微镜、扫描电镜、X射线衍射分析、阻尼性能测定仪等,研究了Cu-11Al-5Mn-RE合金在不同温度时效处理后的组织形态和性能。结果表明:Cu-11Al-5Mn-RE合金200℃时效后阻尼性能最好,在400℃时效后仍具有一定的阻尼能力;该合金具有较强的抗马氏体分解和抗中温时效能力。The microstructure and properties of Cu-11Al-SMn-RE alloy aged at different temperature were studied by means of OM, SEM, X-ray diffraction and damping detection. The results show that the alloy＇s damping capacity aged at 200 ℃ is the best, and at 400 ℃ its mechanical properties decrease while its damping capacity still remains in a certain value which indicates that it has a better resistance to martensite decomposition and to aging at moderate temperature.
