Texture evolution during deformation of an Al-6%Cu-0.4%Zr superplastic alloy
2006
Eddahbi, Mohamed | Carsí, Manuel | Ruano, Oscar Antonio
Texture measurements of the as-received rolled Al-6%Cu-0.4%Zr alloy revealed that a copper component, {311} < 233>, is developed at the surface and a S component, {631} < 113>, is formed at the middle of the sheet. During early stages of superplastic deformation at 480 C/ 5•10–4 s–1 the intensity of the Cu component increases slightly whereas the S component changes toward the brass component Bs, {110} < 112>, by a slip process. For larger strains, both components decrease by a grain boundary sliding mechanism.
