The results indicate that the shear magnitude for the β→a″ transformation of these Ti alloys ranged from 0.03070 to 0.09551. The substructure of a″ martensite is made of the internal twins. The ratio of the twin thickness in a″ martensite of most Ti alloys is from 1 to 4. The volume change of β→a″ phase transformation in partial alloys is within 0.01. These features seem to identify the thermoelastic martensite transformation taking a crystallographic view. 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/I5/121 1 李永森,金属学报,22(1986) ,212． 2 Young, M.; Levine, E.; Margolin, H., Metall.
