Recrystallization is slow at its initial stage due to the small number of nucleation points. When this number reaches a high level, the recrystallization accelerates. When the recrystallized fraction reaches 50%, the recrystallization rate is the highest. Subsequently, new grains grow and touch each other, and the parent structure becomes less and less, so the recrystallization rate decreases. Upon the recrystallized fraction reaching 90%, the recrystallization becomes much slower than before. Figure 6a also shows that the time needed for complete recrystallization is shortened with the increase of deformation. |
