我们提出的结果，准静态循环拉伸试验的Cu-Al-Mn形状记忆合金（SMA）棒的4和8毫米直径，以检查其超弹性和其他机械性能密切相关的地震应用。Cu-Al-Mn形状记忆合金棒材的回复应变超过8%，断裂应变超过17%。在两个棒中均未观察到低周疲劳。从测试中获得的机械性能，沿着与Ni-Ti SMA相比更低的材料成本和更高的可加工性，证明了本发明的Cu-Al-Mn SMA棒用于地震应用的高潜力。版权所有（C）2010约翰威利父子有限公司
We present the results of the quasi-static cyclic tensile tests of Cu-Al-Mn shape memory alloy (SMA) bars of 4 and 8 mm diameters to examine their superelasticity and other mechanical properties closely related to seismic applications. The present Cu-Al-Mn SMA bars have achieved the recovery strains of over 8% and the fracture strains of over 17%. Low-cycle fatigue was observed in neither of the bars. The mechanical properties obtained from the test, along with the lower material cost and higher machinability than Ni-Ti SMAs, demonstrate the high potential of the present Cu-Al-Mn SMA bars to be used in seismic applications.
