“…15) Other details, such as equations, solving procedures, etc., can be found elsewhere. 16,17) The deformation gradient, 18) which was obtained from the actual deformation behavior, was converted to the velocity gradient, 18) which later was used as the input data for the texture analysis. The velocity gradient obtained from the deformation gradient contains two terms, which were contributed by the plastic rotation due to dislocation slip (i.e., the symmetric part of the velocity gradient) and the rigid body rotation during the shear deformation (i.e., the skewed part of the velocity gradient).…”

The effects of deformation history on the texture evolution in an aluminum alloy during two different shear deforming processes, i.e., equal channel angular pressing (ECAP) and dissimilar channel angular pressing (DCAP) were comparatively investigated. Simulation based on the Taylor model showed that the texture evolution during DCAP was very similar to that of ECAP up to the region, a so-called 'zero dilatation line'. Beyond this line, the texture continued to evolve by rotating about the transverse direction (TD) by 10-15 during ECAP, whereas the texture hardly evolved during DCAP. These analytical observations were verified experimentally.

The crystallographic orientation rotation behaviors in aluminum alloys during dissimilar channel angular pressing (DCAP) were investigated. Experiments were conducted to observe the texture evolution due to DCAP. Texture simulation using the full constraint Taylor calculations based on the rate sensitivity model was also carried out both to explain the experimental results and to elucidate the rotation behaviors of the individual orientations due to DCAP.
