The microstructural evolution in a Mg–2.0Zn–0.8wt%Gd alloy during hot rolling was investigated. {10•2} twinning and shear bands were found after the rough-rolling process, while only shear bands were found after the finish-rolling process. The shear bands were observed mainly in grains with their c-axis parallel to the normal direction of the rolling sheets and were suggested to were originated by low-angle boundaries. Continuous dynamic recrystallization occurred around the shear bands as well as within the dynamic recrystallized grains inside the shear bands.
