| 英文摘要 | The push-pull cyclic deformation of a copper bicrystal with components rotated along the grain boundary (GB) was carried out under constant plastic strain amplitude at room temperature. The plastic strain amplitude was 1.5 x 10(-3). The evolution of slip morphology and dislocation structure was observed by using SEM-ECC technology. With components rotating, the dislocation structure changes gradually from the slip band to the deformation band acting with GB respectively. This phenomenon was caused by the geometrical effect of the rotating crystal planes. The second type of deformation band (DB II) blockaded the impingement of the primary slip system band. The formation of dislocation free zone (DFZ) at GB was resulted from the formation of DB II. When the secondary slip system interacted with the DB II, the wall structure of DB II turned into the cell structure gradaully. |
