説明
In order to clarify the effect of piled-up dislocations on the strain induced boundary migration (SIBM), deformation and recrystallization experiments were performed using an aluminum bicrystal specimen with twin boundary at initial orientation. During the deformation to 20% strain, inhomogeneous deformation took place near the grain boundary (GB). Two kinds of dislocations, edge and screw ones, were piled up against the GB in one component crystal. In the other crystal, edge dislocations were piled up against it. After the annealing, the SIBM was recognized along the original GB. The interaction of the piled-up dislocations was considered to occur at the GB, and it would influence the recrystallization behavior. Since the screw dislocations in one crystal were transmitted during the deformation to the other crystal through the GB because of the special orientation and geometric conditions, they could not be retained stably near or at the GB. In contrast, the edge dislocations introduced into the GB in both crystals were accumulated each other near or at the GB, thereby the component of tilt boundary took part in the original twin boundary. Therefore, it was understood that the SIBM resulted from the annihilation and rearrangement of these dislocations.
