Evolution of {001}(110) orientation and related lattice rotation of Al alloy 6111 during rolling

The texture evolution and lattice rotation in At 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 ss fiber, including the brass orientation, by lattice rotation around special directions. Compared with the symmetrical rolling, the {001} < 110 > component in the surface laver on the slower roller side evolves more quickly into the orientations along the ss fiber during asymmetrical rolling, while that in the surface laver on the faster roller side evolves more slowly.
