The K_(um) of positive value varies with annealing time t_a as a linear function of lg t_a and with temperature T in proportion to M_s~(4.6)(T). However, the K_(us) of negative value varies reversibly in a relaxation manner when tension is applied to or removed from the annealed samples and with temperature T in proportion to M_s~(7.5)(T). The behaviour has been qualitatively interpreted using a distortion-directional ordering model. 收稿日期: 1984-05-18      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 陈笃行 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I5/441 1 陈笃行,金属学报,20(1984) .B212． 2 Gibbs, M.
