It was found to be related to the increase of interfaces of parent-martensite according to metallographic examinaětion. The authors put forward a model based on the hysteresis loss mechanism associated with stress-induced motion of the interface dislocations. A new Q~(-1) peak above M_s was observed. It was confirmed to be a relaxation peak due to a certain thermal activation process. For AuCd(46.1 at.-％ Cd)alloy, normal bcc(?)orthorhombic transition changed to bcc(?)hexagonal transition after 1—2 measuring runs. It is suggested that defects play a central role in the change. 收稿日期: 1982-01-18      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 杨照金 邹一峰 张志方 王业宁 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I1/21 1 王业宁;杨正举;祝和;马进超,南京大学学报,7(1963) ,1． 2 王业宁;朱建中,物理学报,15(1959) ,341． 3 Delorme, J.
