It showed that the hysteresis behaviour of cyclic transformation changed, M, and A_f temperature shifted to higher temperatures while the M_f and A_s temperatures remained constant. The amount of martensite undergoing cyclic transformation decreased. These changes appeared to saturate at 300 cycles and could be partly recovered during room temperature holding. The morphology and mode of transformation also changed. During the second cycling transformation occurred in two ways: martensite needles grow in a continuous manner and in a "burst" process. After 60 cycles no burst type transformation occurred during further cycling. 收稿日期: 1982-05-18      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 李健纯 G.S.Ansell 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I5/544 1 Horace P.; Massalski, T.
