本文研究了Ni对CuZnAl系合金的形状记忆性能和力学性能的影响。結果表明:合金中加入Ni后,(1)相变温度Ms变化不大,但相变热滞减小;(2)B2→DO_3有序转变温区变宽且移向高温,从而去马氏体稳定化措施所用的淬火介质也需要作相应调整;(3)马氏体相或母相的屈服强度略有下降,而硬化系数则略有增加,Ni还使CuZnAl合金中α相析出变得困难。这些影响主要是由于Ni的加入,改变了合金中原子间互作用能。 In this paper, the effect of Ni on the shape memory properties and mechanical properties of CuZnAl-based alloys was investigated. The results show that (1) phase change temperature Ms does not change much, but the phase transition temperature hysteresis decreases when Ni is added to the alloy; (2) B2 → DO_3 ordered transition widens and moves to high temperature, (3) the yield strength of the martensite phase or the parent phase slightly decreases, while the hardening coefficient increases slightly, and Ni also precipitates the α phase in the CuZnAl alloy to become difficult. These effects are mainly due to the addition of Ni, changing the interaction energy between atoms in the alloy.
