一、前言形状记忆合金作为一种新型功能材料,特别引人注目。20年来,全世界已有几十个实验室在对其进行研究。据不完全统计,现已发表的有关Ti-Ni合金的论文就有400余篇,获得专利的Ti-Ni器件已有100多种。Ti-Ni以外的形状记忆合金如Cu-Al-Ni、Cu-Zn-Sn等的研究也很多。
I. INTRODUCTION Shape memory alloys are particularly attractive as a new type of functional material. Twenty dozens of laboratories around the world are studying it in 20 years. According to incomplete statistics, more than 400 papers have been published on Ti-Ni alloys and more than 100 have been patented Ti-Ni devices. There are many studies on shape memory alloys such as Cu-Al-Ni and Cu-Zn-Sn other than Ti-Ni.
