Abstract:The texture evolution and lattice rotation in Al alloy 6111 with an initial {001}〈 110〉 component during symmetrical and asymmetrical rolling were investigated by means of orientation distribution function(ODF). The results show that the as-rolled initial {001}〈 110〉 orientation evolves into not only the copper orientation but also all the other orientations along the β fiber, including the brass orientation, by lattice rotation around special directions. Compared with the symmetrical rolling, the {001}〈 110〉 component in the surface layer on the slower roller side evolves more quickly into the orientations along the β fiber during asymmetrical rolling, while that in the surface layer on the faster roller side evolves more slowly.
Key words: Al alloy; symmetrical rolling; asymmetrical rolling; {001}〈 110〉 orientation
