The profiles of endothermic and exothermic peaks of one way shape memory alloy are different from those of two way shape memory alloy.The former shows smooth peaks while the other shows bumpy peaks. Besides, the heat of martensitic transformation of two way shape memory alloy is about 25% less than that of one way shape memory alloy.Correspondent: TAN Shusong, professor, (Department of Materials, Central South University of Technology,Changsha 410083) Key words： one way memory alloy    two way memory alloy    heat of transformation 收稿日期: 1994-09-18      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 谭树松 徐惠彬 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1994/V30/I9/404 1LiuY,MccormickPG．ActaMetallMater,1990;38:13212ContadoL,GueninG．ActaMetallMater,1990;38:12673GueninG．EuropeanconferenceontheMartensiticTransformationinScienceandTechnology．Bochum,FRG,1989:394StalmansR,VanHumbeeckJ,DelaeyL．MaterTransJIM,1992;33:2985ContardoL,GueninG．MaterSciForum,1990;56-58:5296SakamotoH,SugimotoK,NakamuraY,TanakaA,ShimizuK．MaterTransJIM,1991;32:1287XuH,TanS．ScrMetallMater．1991;25:1507 [1] 蒋青.
