It was shown that two kinds of phase transformation, namely, of the martensite and the R-phase in the alloy are done between 40-50℃. The structure of martensite and of R-phase is distorted monoclinic B_(19) and B_2 respectively. The Rphase does not reveal a pre-transformation and remains relative stable till -185℃. Thus, the phase transformation in an equal atom Ni-Ti alloy takes place as:β(?)β+R+M(B_(19))(?)R+M(B_(19)). 收稿日期: 1983-05-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 陈丽君 周勤友 洪卫卿 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I5/21 1 Wang, F.
