Intensifying Goss/Brass texture ratio in AA2024 by asymmetric cold rolling

The effect of asymmetric cold rolling on the crystallographic texture of the AA2024 aluminum alloy was investigated. The texture after asymmetric cold rolling consisted of the strong Goss {011}〈100〉, Goss-Brass {011}〈115〉, Brass {011}〈211〉, and Rotated Goss {011}〈011〉 components (i.e. a strong α-fiber 〈011〉∥ND). It was found that asymmetric cold rolling present great differences in texture evolution relative to conventional cold rolling. The results showed that the asymmetric cold rolling of AA2024 at 20% and 40% thickness reductions led to increasing the Goss/Brass texture ratio to 1.44 and 1.32, respectively.
