TiNi形状记忆合金因其良好的功能性能和高的力学性能,是目前应用最为成功的形状记忆合金。形状记忆合金的形状记忆功能与合金成分密切相关,Ni的原子体积分数变化0.1%,其相变温度会变化10K,因此,生产中要保证合金成分均匀是其关键。 Due to its good functional properties and high mechanical properties, TiNi shape memory alloys are currently the most successful shape memory alloys. The shape memory function of shape memory alloy is closely related to the alloy composition. The atomic volume fraction of Ni changes by 0.1%, and the phase transition temperature changes by 10K. Therefore, it is crucial to ensure uniform alloy composition in production.
