AbstractThis paper reports three distinct but related projects. In the first, an attempt is made to simulate BCC rolling textures by including a conditional deformation banding criterion modeled in a Taylor/Chin framework. The model is then run backwards to find the origins of the alpha and gamma fibers. The practical importance of this work is to produce an ideal deformation texture from which it might be possible to maximise the development of {111} and to minimise {100} during rolling, since it is well known that {111} recrystallized components are associated with the gamma fibre. The second investigation is concerned with the origins of the {111} texture in a batch annealing steel. It is demonstrated that the gamma fibre grains are heavily shear banded, and the nucleation of {111} mains occurs in these bands. The shear band material is a ND-rotated {111} component. Clearly, the condition leading to extreme strain localisation is determined by both the slip geometry and the solute/precipitate state. Finally an investigation into the origins of {111} in IF steels using EBSP (Electron Back-Scattering Pattern) on longitudinal sections has failed to identify any sites of strain localisation for nucleation of these grains but it is shown that grain growth strengthens {111} components.
