• The substructures and recrystallization of the cold-rolled iron crystals with different initial orientations have been studied by transmission electron microscopy. When the crystals as-rolled are annealed at increasing temperature, dislocations forming cell structure rearrange to cause subgrains, whose orientations are found among those of the cells, and then recrystallized grains generally appear among the subgrains. The recrystallized grains are exclusively found in the matrix made up of the subgrains having smaller size as well as larger misorientation. There is strong reluctance to recrystallization when most of the segment of the subgrain boundaries consist of dislocation network resulting from the dislocation reaction such as 1/2a[111]+1/2a[1^^-1^^-1] ⇾ a[001]. The subgrain growth due to the coalescence is found from the close examination of the distribution of dislocations in the subgrains. The formation of recrystallization nucleus and the recrystallization tendency are discussed on the basis of the coalescence mechanism.
