An ultra low carbon stee] was finish rolled in the ferrite range, cold rolled and annealed. Ouantitative analysis of the deformation and annealing textures indicated that high stored energy nucleation was the dominant recrystailization mechanism after a conventional rolling reduction of 75"/•. When the rolling reduction was increased to 95'/•, texture formation during recrystallization was controlled by both oriented nucleation and selective growth; this involves the ra pid growth of nuclei
