Phase-field simulation of the migration of a recrystallization front was performed based on the unified subgrain growth theory. The effects of the subgrain structure developed in the deformed state on a recrystallization front were investigated with the focus on the growing of the recrystallizing grain. Especially, the effects of the mean misorientation, , and the initial mean subgrain radius, < R-C >(0), in unrecrystallized region were evaluated. The critical misorientation angle, which gives the maximum migration distance, was highly dependent on the relations between misorientation and boundary properties (i.e. energy and mobility). And the value of < R-C >(0) had significant effects on the velocity of the recrystallization front if the value of was favorable for discontinuous recrystallization. (c) 2007 Elsevier B.V.
