| 摘 要： | 本文着重地研究了Ti-13at.-％Ni-37at.-％Pd合金的高温形状记忆效应与预形变温度的关系.该合金A_s温度是620K,具有单程形状记忆效应和双程形状记忆效应。在620—640K温度预形变,可以得到最大的形状记忆应变,这与在此温区产生的最小可逆应变能有关。

| Abstract: | High temperature shape memory effect depended on the pre-deformation temperature of the Ti_(50)Ni_(13)Pd_(37) alloy has been studied. This alloy, ofwhich the reverse transformation start temperature on heating is 620 K, has bothone-way and two-way shape memory effects. The maximum shape memory strain ofthe alloy may be obtained under pre-deformation in the range of 620 to 640 K.This seems to be related to the minimum recoverable strain energy emerged fromthe above mentioned temperature range. |
