A Taylor-type model was used to investigate the contribution made by dislocation slip on {123} glide planes during the rolling deformation of body-centered cubic transition metals. Since the movement of dislocations on the active glide systems gave rise to characteristic grain rotations, the method of quantitative texture analysis was used to investigate the validity of the predictions. The computations were carried out by permitting dislocation slip on {110}, {112} and {123} glide planes; each of which contained a ½<111> Burgers vector. The simulated crystallographic textures revealed a very satisfactory agreement with experimentally determined rolling textures. The results confirmed that the {123}<111> glide systems contributed a considerable amount of the shear which had formerly been attributed only to {110}<111> and {112}<111> slip systems.
