Abstract
In order to clarify the effect of edge dislocations on the occurrence of the strain-induced boundary migration (SIBM), aluminum bicrystals each with a <211> tilt grain boundary were prepared. The bicrystals were tensile-deformed to 0.3 and annealed under certain conditions. Consequently, in the grain boundary recrystallization in the bicrystals with the primary edge dislocations in the component crystal(s) parallel to the <211> tilt boundaries of large tilt angles, the SIBM mechanism played an important role. It could be considered that the phenomena of the SIBM are strongly related to the motion and annihilation of edge dislocations or their array, and the migration of the tilt boundaries with large tilt angles.
