本文研究了CuZnAl系合金马氏体稳定化去除后,合金元素及热处理方式对形状记忆恢复力的影响。结果表明,合金形状记忆恢复力的大小与其屈服强度有关,改变合金成份或变更热处理方式使合金屈服强度升高,形状记忆恢复力将相应增大,有利于提高合金的恢复性能,合金处于拘束状态时将使恢复温区明显增大,但对恢复开始点As基本没有影响。
In this paper, the effect of alloying elements and heat treatment methods on shape memory resilience after the martensite stabilization of CuZnAl-based alloys was studied. The results show that the shape resilience of the shape memory alloy is related to the yield strength. Changing the alloy composition or changing the heat treatment method can increase the yield strength of the alloy and increase the shape memory resilience, which is beneficial to improve the recovery performance of the alloy and the alloy is in a restrained state Will significantly increase the recovery temperature zone, but has little effect on the recovery start point As.
