摘要

The most important driving force for recrystallisation is known to be the energy stored due to dislocations. Dislocations cannot be related to the recrystallisation texture, unless they give rise to some anisotropic characteristics. Attempts to explain the recrystallisation textures of fcc and bcc metals often result in conflicting results. In 1995, the author advanced a model for explaining the recrystallisation textures, which is called the strain-energy release maximisation model. This article elaborates on the model, in which the directionality of internal stresses caused by the dislocation arrays associated with deformation modes and deposition textures is related to the recrystallisation texture. The evolution of various recrystallisation textures including the {001} texture in cold-rolled fcc metals and the {111} textures in cold-rolled IF steel could be explained by the model. The evolution of the {001} and {111} textures has been discussed in detail to make the model better understood. The transition from the {111} rolling texture to the {111} recrystallisation texture in steel has been discussed based on the model.
