説明

In order to investigate the distributions of recrystallized grains in the surface and inner layers, recrystallized grains in 99.99 mass% aluminum single crystals with the Schmid factor of 0.5 deformed in tension to the strain of 30% were examined. After annealing under certain conditions recrystallized grains are preferentially formed along the deformation bands near the surface layer and grown into the inner layer along the corresponding deformation bands. Most of the orientations of the recrystallized grains are obtained by the rotation of the deformed matrix about the axis normal to one of the four {111} planes. Less than 10% of the total recrystallzied grains are formed due to the strain induced boundary migration. The reason why the formation of recrystallized grains along the deformation bands in the surface layer occurs at the earlier stage than that in the inner layers should not be the temperature difference between the surface and the inner layer, but the existence of the free surface.
