Magnesium alloys and their composites have great potential as structural materials because of their low density and excellent specific properties. The properties of Mg alloys and their composites can be enhanced considerably by grain refinement. Severe plastic deformation (SPD) is a very attractive tool for the production of bulk ultrafine-grained materials with superior properties. During the last fifteen years, Harbin Institute of Technology (HIT) has carried out extensive research on SPD of Mg alloys and their composites. This presentation introduces the research progress on the ultrafine-grained Mg alloys and their composites processed by equal-channel angular pressing (ECAP)accumulative roll bonding (ARB), multi-directional forging (MDF) and high pressure torsion (HPT) in HIT. The microstructural development and the influence of microstructure on mechanical properties and damping capacity of the ultrafine-grained Mg/Al multilayed composite sheet fabricated by accumulative roll bonding are discussed in detail.
