Hot rolling was carried out in this study to modify the microstructures of an extruded Mg-6Al-1Sn-0.3Mn alloy sheet and investigate its effects on mechanical properties. After hot rolling, the grains and second phase of the extruded alloy sheet were remarkably refined, and the c-axis of a few grains was parallel to the transverse direction. The strength improvement was mainly attributed to the grain and Mg(17)Al(12 )particle refinement due to the Hall-Petch effect and the Orowan mechanism. The random orientation of the fine grains resulted in improving ductility and anisotropy.
