Texture evolution during equal channel angular extrusion (ECAE): Part II. An effect of post-deformation annealing

The influence of annealing on texture after ECAE of Al–0.5Cu alloy is described. It is shown that annealing presents multiple opportunities to control texture, which are correlated with the transformations of microstructures created during various ECAE strain paths. Up to the temperature of primary recrystallization, two domains are distinguishable. Before four passes, large modifications in texture strength and/or orientation are obtained. After four passes, except in some cases for route C, rather limited changes in texture strength and orientations are observed. Annealing at higher temperatures decreases texture strength in both domains. Route C exhibits a specific behavior showing significant changes even after four passes.
