On Penetration of Shear Texture into the Rolled Aluminum and Copper

Abstract

The most important cause of the macroscopic inhomogeneity of texture is the nonuniformity of the penetration of the shear deformation through the thickness of the rolled metal. The authors have proposed a method making possible the observation of the penetration of shear texture from layer to layer. The method involves measuring the angles that describe the rotation of the {001}«110» shear orientation toward the copper-type rolling texture. Rolling with large draughts causes the penetration of the shear texture from the surface toward the sheet center, inducing a change in the characteristics of the inhomogeneity of texture. This mechanism is related both to the geometry of the rolling gap and to the mechanical properties of the deformed metal.
