Ultrafine-grained (UFG) magnesium materials offer unique properties, for example high strength-to-weight ratio or improved corrosion resistance. Severe plastic deformation methods are very efficient for manufacturing UFG compact bulk material. Namely equal-channel angular pressing (ECAP) and high pressure torsion (HPT) currently attract significant attention of material science community. This contribution summarizes experimental study of UFG magnesium alloys. Investigation utilized light microscopy, transmission and scanning electron microscopy, electron backscatter diffraction (EBSD), microhardness measurements, tensile tests and other techniques. Results are discussed in light of other experimental and theoretical studies.
