The evolution of the crystallographic rolling textures of B2 and DO3 ordered polycrystalline materials was described by means of Taylor-type simulations. The contribution which crystallographic slip made to various types of glide system, especially the effect of {112}<111> slip, was examined. Full-constraint Taylor-type conditions were assumed when simulating low reductions. The lath model was used to describe intermediate reductions, and the pancake model was used for large reductions. The ratio of the critical resolved shear stresses for the {110}<111> and {112}<111> slip systems was varied. It was found that the predictions that were obtained by impeding {110}<111> systems and promoting {112}<111> systems were in good agreement with experiment. The results were explained in terms of the energy of antiphase boundaries, and dislocation core effects.
