Fabricating nanostructured architecture through severe plastic deformation (SPD) has been proved to be an effective way to attain high strength magnesium alloys. However, the SPD induced grain refinement in magnesium alloys can always be hindered by accompanying dynamic recrystallization and grain growth. In this study, a binary Mg-Gd alloy was prepared by the accumulative roll-bonding (ARB) processing. The microstructure after processing is characterized by lamellar grain structures with an average boundary spacing of ~150 nm. The refinement of structure is attributed to the formation of dislocation boundaries, stacking faults, deformation twins and Gd-rich clusters. The study shows a new probability of fabricating high strength nanostructured magnesium alloy with nanoscale defects and complexions.
