摘要 利用自制合金低温形变量测量装置以及测量低温电阻、低温膨胀、X-射线、扫描电镜等检测手段,研究热处理对55％Cu-35％Al-10％(Mn+Si)合金低温形状记忆性能的影响。合金试样较理想的热处理工艺为950℃保温10min+室温水淬+200℃回火10min,形状记忆温度为100K左右。自制的形变量测量装置可用于低温形状记忆性能测定试验。 The effect of heat treatment on shape memory effect of 55%Cu-35% Al-10% (Mn +Si) alloy is investigated with a device designed to measure shape change effect of shape memory alloy, cryogenic electrical resistance, cryogenic dilatometric measuring, X-ray diffraction and SEM. The optimum heat treatment process is 950℃ for 10min + water quenching + 200℃ annealing for 10min, the martensitic transformation temperature is approximately 100K for treated alloy. The designed device is proved to be effective in shape change effect measuring of shape memory alloy.
