摘要	The effect of rolling reduction of the last pass on the dislocation slip and twinning behavior during direct hot rolling of a cast WE43 magnesium alloy at 480 degrees C was investigated. The results showed that prismatic < a > slip was always the main deformation mode during rolling at 480 degrees C. In addition, the activated twinning type was associated with rolling reduction. The {10 (1) over bar2} extension twinning was activated at a slight rolling reduction (2%), while {10 (1) over bar1} compression twinning and {10 (1) over bar1} -{10 (1) over bar2} double twinning were activated at larger rolling reduction (12% and 20%). Schmid factor calculation showed that the activation of {10 (1) over bar2} extension twin variants followed the Schmid Law, whereas the activation of {10 (1) over bar1} compression twin variants did not follow it. Even if the rolling reduction reached 20%, almost no dynamic recrystallization (DRX) grains were found, presumably because the amount of deformation required for DRX to occur was not reached.
