From the analysis of hysterisis loops, it is suggested that the decreasein back stress dominates the cyclic process of Cu-Zn alloy with planar slip mode, while thedecrease in frictional stress is the main factor affecting the behaviour of Cu with wavy slipmode.The relation between the dislocation configuration and internal stress has been also dis-cussed. By means of the relation just mentioned, the variations of dislocation configurationbefore and after fatigue of the two materials, the differences in their softening mechanismand mechanical behaviour could be interpreted. Key words： slip mode    fatigue softening    hysteresis loop    internal stress. 收稿日期: 1993-04-18      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 柴惠芬 阮征 范群成 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1993/V29/I4/7 1 Prabhakara Sarma D, Vasudevan R.
