Abstract
The through-thickness texture variations in ∼40 pct cold-rolled polycrystalline aluminum were studied using X-ray diffraction and the electron backscattering pattern (EBSP) technique. The influence of the roll-gap geometry and of sequences of small and intermediate draughts on the development of deformation textures in multipass rolling was considered. It was found that similar textures were formed near the surface and in the central layers of all specimens, while, in the intermediate layers of different plates, different textures were observed. Small draughts gave rise to the shear texture in the intermediate layers, while no pronounced shear texture was revealed anywhere through the thickness of plates rolled with intermediate draughts. It was found that small-draught rolling only has a pronounced effect on the texture if it accounts for a significant strain in the rolling schedule. It was found, furthermore, that nonuniformity of the initial recrystallization texture may be retained in the texture after ∼40 pct rolling.
