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.      Received:  18 April 1993      Service E-mail this article Add to citation manager E-mail Alert RSS Collect articles（0） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1993/V29/I4/7 1 Prabhakara Sarma D, Vasudevan R.
