The paper presents a correlation between microstructure and crystallographic texture in hot-rolled AZ31 magnesium alloy. The microstructure and texture evolution are investigated using optical microscopy, field emission scanning electron microscopy, X-ray diffraction, respectively. The results indicated discontinuous dynamic recrystallization, twinning dynamic recrystallization, and particle stimulated nucleation as the main mechanisms during hot deformation. The average size of grains decreased from 19 to 1 μm as the rolling reduction increased from 0 to 60%. A large area fraction of new grains was observed at 40% thickness reduction. At the beginning of plastic deformation, basal slip and extension twinning increased the intensity of {0001} basal fiber texture. Dynamic recrystallization had a considerable effect on weakening the basal texture. Interestingly, some unusual highly stable components including $$ (01\bar{1}3)[7\bar{8}13],(01\bar{1}3)[\bar{2}110] , $$(011¯3)[78¯13],(011¯3)[2¯110], and $$ (01\bar{1}3)[14\bar{5}\bar{3}] $$(011¯3)[145¯3¯] existed at all deformation conditions and their intensity remained nearly unchanged.
