The researchers mainly focuses on developing various methods to fabricate the hierarchical nanostructured metals, exploring their intrinsic relationship between the hierarchical microstructure and mechanical properties and fatigue and fracture behavior, clarifying their plastic deformation and fatigue damage mechanisms. A central objective is to get a real breakthrough in the trade-off trend between strength and other mechanical properties (ductility, work hardening, fatigue, fracture and so on), to understand the relationship of microstructure-properties, breaking through the technical bottleneck of the development of high-performance nanostructured metallic materials and promoting a scientific foundation for the application of nanostructured metallic materials.
