因为具有形状记忆效应和超弹性,TiNi形状记忆合金已经广泛用做功能材料和生物材料。最近,由不完全相变诱发的特殊的温度记忆效应现象引起关注:如果从马氏体到奥氏体的逆相变在第一次加热中在温度TI处被中断,而后冷却到马氏体相变终了温度以下,在随后的加热过程会出现被一个动力学中断点TS分开的两阶段逆相变,TS可“记住”TI。本文综述了TiNi基形状记忆合金的温度记忆效应及其机制。 TiNi shape memory alloys have been widely used as functional and biomaterials due to their shape memory effect and super elasticity. Recently, the phenomenon of a special temperature-memory effect induced by incomplete phase transition has attracted attention: if the reverse phase change from martensite to austenite is interrupted at the temperature TI in the first heating and then cooled to martensite Below the end-of-phase temperature, a two-stage reverse phase change, separated by a kinetic breakpoint TS, can occur during the subsequent heating and the TS “remembers” TI. This article reviews the temperature memory effect and its mechanism of TiNi-based shape memory alloys.
