As the S-parameter increased to about 80% of the maximum value, the property of the two-way shape memory effect in the alloy may be stabilized. Both microscopic and macroscopic measurements are identical. This result seems to be available not only for establishing an effective and convenient method to analyze the stability of two-way shape memory effect, but also for evaluating such microscopic positron annihilation spectroscopy as a measure of metallic material research. 收稿日期: 1987-02-18      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 王景成 杨士伟 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I2/234 1 杨士伟,秦桂英,上海金属(钢铁分册),1986;8(3) :26 2 宫崎修一,大塚和弘,金属,1983;53(3) ;38 3 舟久保熙康,形状记忆合金,产业図书株式会社,1984,83 4 Troev T D, Hinode K H, Tanigawa S, et al.
