%X In single-slip-oriented copper single crystals which were cyclically deformed under constant plastic shear strain amplitude control, the persistent slip line (PSL) was first formed in the vein dislocation structure of matrix, and then it was rather quickly transformed into persistent slip band (PSB) under consecutive cycling. During annealing for the fatigued copper single crystals with PSBs the penetrating force caused by different void densities drives dislocations motion, makes some parts of PSB thinning and finally PSBs disappeared under the mechanism of annihilation part by part. Because of gradual releasing of the strain energy in annealing process, no recrystallized grain has been observed.
