Ni-Ti形状记忆合金中的相变

Phase Transformations in Ni-Ti Shape Memory Alloys

根据作者的工作、并结合新近文献,对近等原子Ni-Ti合金中的相变作了系统的综述,包括:相变的顺序,无公度相变,R相变,马氏体相变,合金成分及热循环对相变临界温度的影响,逆相变及沉淀。

According to the present author's works and referencing the recent literatures, a brief and systematic review on phase transformations in nearly equal-atomic Ni-Ti alloys is made, including the sequence of transformations, the incommensurate transition, the R phase transformation, the martensitic transformation, the effect of alloy composition and thermal cycling on the critical points of transformations, the reverse transformation and the precipitation.
