采用与文献 [1]相同组分的 Ni Ti合金材料 ,将其用不同的热处理工艺进行处理 ,分析了不同热处理后其超弹性滞回性能在不同温度和不同应变幅值下的变化规律 ;通过与文献 [1]的对比 ,探讨了热处理前后该材料力学性能的变化以及加载频率的影响
Ni Ti alloy with the same composition as in [1] was used and treated with different heat treatment processes. The changes of the hyperelastic hysteresis properties at different temperatures and different strain amplitudes after different heat treatments were analyzed. Compared with the literature [1], the mechanical properties of the material before and after heat treatment as well as the impact of loading frequency
