NiTi形状记忆合金记忆效应衰减行为及其机理的研究

STUDY ON SHAPE MEMORY EFFECT DEGRADATION BEHAVIOUR AND ITS MECHANISM OF NiTi SHAPE MEMORY ALLOY

对近等原子比ＮｉＴｉ形状记忆合金经几种不同工艺处理后的记忆效应衰减行为进行了研究。利用透射电镜对其微观组织结构作了观察，并从微观结构方面入手，对记忆效应衰减机理进行了分析与探讨。

Shape memory effect degradation behaviour of near equiatomic NiTi shape memory alloy was examined under two different techniques. The microstructure of NiTi shape memory alloy and the mechanism of its shape memory effect degradation were studied by means of TEM.
