Textures variation of 3104 aluminum alloy sheets under different rolling conditions

摘要

The textures variation of 3104 aluminum alloy sheets during hot rolling, cold rolling, transverse cold rolling and cross shear rolling were investigated by means of X-ray ODF analysis. The results show that the main texture component {100}<011> becomes stronger with the increase of hot rolling reduction. The cold rolling textures are composed of typical "copper-type" texture components C{112}<111>, S{123}<634>, R/S{124} <211> , B{110} <112> and G{110} <001>, the orientation intensities increase with increasing cold rolling reduction. Compared to the conventional cold rolling with the same amount reduction, the transverse rolling reduces the orientation intensities of each cold rolling textures components, and strengthens the {001} <110> and {110} texture components. During cross shear rolling process, notable difference of intensity of cold rolling textures components were observed from the slow roller side to the fast roller.
