Homogenous rolling and texture modelling in cold rolled low Carbon steel

Abstract

In homogenous deformation, texture development is controlled by dislocation slip but the influence of inhomogeneous deformation is also significant. The development of inhomogeneous deformation structures during rolling can cause different crystal rotations leading to modified texture development. Microstructure development in progressively rolled low carbon steel was followed by a technique depending partially on etching and partially on channelling contrast imaging. Grain subdivision or Deformation Banding (DB) caused by plastic deformation was detected and is introduced in texture modelling in a Taylor framework. The model is further developed by incorporating an energy criterion into the model and the predicted rolling textures for BCC materials are shown to give better agreement with measured textures than for models which disregard DB.
