Analysis of textures heterogeneity in cold and warm asymmetrically rolled aluminium

This paper presents some textures obtained on one Al alloy after symmetrical and asymmetrical rolling performed at two different temperatures, and followed by annealing. It is shown that there is a strong influence of rolling temperature and degree of asymmetry on the texture development and its heterogeneity through the thickness of the sheet. In particular, it is shown that the Cube component, originally present in the texture of the as-received material, disappears during warm rolling but re-appears during subsequent annealing. These data indicate that the exact schedule to suppress completely this component is not yet found but also that the recrystallization mechanisms are very sensitive to the exact rolling schedule. ► Asymmetrical rolling reduces the amount of the Cube component after deformation in Al. ► The influence of asymmetry is stronger at elevated temperatures. ► The annealing texture tends to isotropy after high T asymmetrical rolling.
