The magnesium alloy texture can be modified during deformation, recrystallization and phase transformations and can be linked to improve the alloy ductility. In that sense, it was investigated the texture development of a commercial AZ31B magnesium alloy sheet after cold and hot deformation, using electron backscatter diffraction (EBSD) and X-ray diffraction. EBSD orientation map and (0001), (100) e (110) and (101) pole figures of deformed samples showed that the texture of cold rolled sheets was characterized by a strong (0001) basal fibre texture with a double-peak distribution, where the basal poles were tilted about ±10° deg away from the normal direction and toward the rolling direction. While the texture of hot-rolled samples was characterized by a (0001) recrystallization texture. Twins and dynamic recrystallized grains played a vital role during deformation, weakening the intense basal texture.
