The computer simulation had been made of a typical thermoelastic material TiNi by advanced several possible martensitic transformation models. They are K_l=(111)_M, (111)_M (twinned crystal type Ⅰ) and η_l=[110]_M (type Ⅱ) on the TiNi(β) where the structural mode of the martensite is characterized by the lattice parameters being a=0.2889, b=0.4120, c=0.4622nm and β=96.8°; and K_l=(111)_M, (111)_M (type Ⅰ)on theTiNi(γ) where the structural mode of the martensite is characterized by the lattice parameters being a=0.2885, b=0.4622,c=0.4120nm and γ=96.8°. Both of them are capable of satisfying the requirements that the interphase interface is the plane of zero average distortion, and are found to be in agreement with the available experimental results given by the other authors. 收稿日期: 1986-05-18      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 李永森 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I5/112 1 Lieberman, D.S.; Wechsler, M.S.; Read, T.A., J.
