【摘要】 通过扭转法和电阻测量法对Cu-Zn合金的形状记忆效应进行了实验研究。发现在Ms点以上,不存在热弹性马氏体的情况下,由应力诱发马氏体可以引起形状记忆效应。另外,在Ms点以下有热弹性马氏体的情况下,根据实验结果可以证明,应力诱发马氏体在形状记忆效应中仍然起主要作用。更多还原

【Abstract】 The shape memory effect(SME) in Cu-Zn alloy was studied by the twisting deformation method and electric resistance methods. The results show that when the temperature above Ma, there is no thermoelastic mar tensite(TEM), but show perfect SME, so that the SME is entirely caused by stress-induced martensite (SIM). On the other hand, when the temperature below Ms, though there is TEM transformation, the SME is also mainly caused by the SIM.更多还原
