用电阻、热分析和X射线衍射等方法对CuZnAl(Mn)合金的马氏体稳定化现象进行了研究。结果表明,马氏体稳定化倾向决定于二种转变过程:马氏体逆转为母相和逆转前M9R马氏体转变为 M18R马氏体。1～2%Mn 的加入使得M9R马氏体转变为M18R马氏体的过程在M9R马氏体逆转为母相之前完成,因此MN减小CuZnAl记忆合金的马氏体稳定化倾向。 The martensitic stabilization of CuZnAl (Mn) alloy was studied by means of electrical resistance, thermal analysis and X-ray diffraction. The results show that the tendency of martensite stabilization depends on two transition processes: the martensite reverses to the mother phase, and the M9R martensitic transformation to M18R martensite before the reversal. The addition of 1 ~ 2% Mn makes M9R martensitic transformation into M18R martensite process before M9R martensite reversal to mother phase, so MN reduces the tendency of CuZnAl memory alloy martensite stabilization.
