Small-strain hot-rolling experiments have been conducted on AZ31B twin-roll cast sheets. Optical microscope (OM), transmission electron microscope (TEM) and electron backscattered diffraction (EBSD) tests were used to study the various twinning behaviors in the rolling process. After 10% hot-rolling, grains lying with C -axes perpendicular to the ND twinned on the {1 0 1¯ 2}〈1 0 1¯ 1〉 system with the largest SF, and rotated to orientations with C -axes aligned with ND, causing a sudden increase in basal texture consequently. With the increase of rolling reduction, {1 0 1¯ 1}−{1 0 1¯ 2} twins began to form in the new oriented grains, following the Schmid law. No evident increase in basal texture was found as rolling strain increased from 10% to 20% due to the inhomogeneous strain located in {1 0 1¯ 1}−{1 0 1¯ 2} twinned regions.
