Abstract

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.
