Texture evolution during deformation of an Al-6%Cu-0.4%Zr superplastic alloy
2006
Eddahbi, M. | CarsÍ, M. | Ruano, O. A.
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.
