摘要
对恒应力约束下降温预应变和室温拉伸预应变TiNi形状记忆合金丝的马氏体逆相变行为进行研究。结果表明,随着预应变的增加,二者的马氏体逆相变温度都上升,应变回复率都下降;但是在相同预应变下,前者的马氏体逆相变温度低于后者,后者的应变回复率却高于前者。
The reverse martensitic transformation behaviors of TiNi shape memory alloy wires prestrained by cooling under constant strain constraint and prestrained by tension at room temperature were investigated. The results show that the reverse martensitic transformation temperatures of both wires increase and the recovery strain ratio of the both decrease with increasing prestrain, however, the reverse martensitic transformation temperature of the former is lower than that of the latter and the recovery strain ratio of the latter is higher than that of the former.
