Texture Changes During Deformation of a 7475 Superplastic Aluminum Sheet Alloy

Abstract

The deformation mechanisms of a fine-grained Al 7475 superplastic alloy deformed under non-optimum conditions for superplasticity, but under which still several hundred per cent of elongation are achieved, have been studied by means of texture analysis. It has been found that crystallographic slip plays an important role in the deformation of this alloy under such conditions. After testing both along the rolling and the transverse directions, the orientations of the texture belonging to the α- and β-fibers are retained. This is not consistent with current models of deformation for randomly oriented polycrystals.
