Effects of thermo-mechanical cycling on recovery strain and temperature of reverse transformation were investigated under constant pre-strain of 5.

96%)下的回复应变和逆相变温度;恒定预应变5。

Effects of thermo-mechanical cycling on recovery strain (RS), critical stress for inducing martensites (σM) and martensitic transformation temperatures (Ms and Mf) of Ti49.

2形状记忆合金的回复应变RS、应力诱发马氏体的临界应力σM以及马氏体相变温度Ms和Mf的影响。

The experimental results show that the recovery strain under 290 MPa stress decreases gradually and tends to be stable with increasing of the cycles and martensit stability, accumulation of the residual strain.

测试了Ti50Ni43Cu7合金在两种应力作用不同循环次数下的回复应变。

Results showed that the TiNi sample after the thermal cycling of partial reverse martensitic transformation exhibited two-step reverse martensitic transformation and two-step recovery strain during the second unconstraint heating process.

利用DSC对预应变TiNi形状记忆合金丝在恒应力约束下的马氏体不完全逆相变进行了研究,发现不完全相变热循环样品在第二次自由态加热过程中出现两步马氏体逆转变和两段应变回复现象。
