The activation of deformation mechanisms in magnesium alloys is Schmid factor-related. The concept of a generalized Schmid factor (G-SF) and a corresponding calculation method were proposed. The G-SF was calculated under a general stress state of plate rolling to discuss the rollability of a textured AZ31B magnesium alloy in terms of the Schmid factor criterion. A low reduction per pass (RPP) is favorable for rollability. The G-SF for basal slip systems of grains in the basal orientation remained constant, but it increased for (0-110)[2-1-10] and (1-100)[11-20] prismatic slip systems with a decrease in RPP. Similarly, the G-SF for all pyramidal slip systems and contraction twinning systems increased with a decrease in RPP. The rollability benefits from such a development trend and makes the synchronous activation of deformation modes possible.
