Effect of initial texture on the evolution of texture and stored energy during recrystallization of interstitial free steel
applying a double cold rolling and annealing treatment, the evolution of the a and gamma fiber components differed from the ones observed in conventional processing. This is attributed to the difference of the initial texture. An increased reduction of stored energy of the {111}< 112 > component was found by monitoring the change of the stored energy during annealing, indicating that the onset of the nucleation stage of recrystallization by relaxation and annihilation of dislocations occurred mainly on the {111}< 112 > component with its higher stored energy. The detailed texture evolution of the double cold rolled specimen during 2(nd) annealing is described by coupling the theory of oriented nucleation and orientation pinning, which is experimentally confirmed by OIM scan.
