THE EVOLUTION OF RECRYSTALLIZATION TEXTURES FROM DEFORMATION TEXTURES

A model for the evolution of recrystallization texture has been suggested. In the model, the most important driving force for recrystallization is assumed to be the stored energy due to dislocations whose arrangement is dependent on the deformation texture, which in turn gives rise to the absolute maximum principal stress direction. The maximum stress direction becomes the minimum elastic modulus direction on recrystallization. The model has been used to explain the evolution of the 〈100〉 recrystallization texture from axisymmetrically deformed fcc metals, the cube recrystallization texture from cold rolled fcc metals, the {111}〈112〉 recrystallization texture from cold rolled bcc iron alloys, and the recrystallization textures from axisymmetrically deformed bcc metals. © 1995.
