摘要
介绍了NiTiZr高温形状记忆合金的研究进展,重点评述了NiTiZr中Zr添加及热处理对合金的相变温度、形状记忆效应的影响,同时探讨了NiTiZr合金加工特性及相变的微观机理,最后提出了需要进一步研究的问题。
The research on NiTiZr high temperature shape memory alloys is reviewed with emphasis on the effect of Zr addition and heat treatment on the alloys transformation, shape memory effect. Processing characteristics and microscopic mechanism of NiTiZr alloy phase transition are also briefly analyzed. Finally, the article presents a di- rection for further research.
