Abstract

The development of the formation of texture in both rolled and annealed f.c.c. metals has been reviewed and limitation in the present understanding identified. Special attention is given to the problems of the deformation texture transition in f.c.c. materials and to the development of cube texture during recrystallization. Inadequacies in the current deformation models are discussed and recent experimental results based on metallographic studies of highly deformed metals presented. The work demonstrates the importance of deformation banding as a mechanism of deformation which significantly influences both the development of the deformation texture and the subsequent recrystallization process. Consideration of the additional deformation modes enables a new deformation model to be developed which gives results in better agreement with experiment. Experiments on cube texture formation in relation to previous recrystallization studies and to the role played by both the oriented-nucleation and the oriented-growth theories in recrystallization is briefly reviewed. Recent work on the role of deformation banding in the formation of cube-oriented volumes having a special orientation relationship with their neighbours is presented, leading to a generalized theory of the cube recrystallization texture formation. © 1994.
