Ductility and strategies for improving ductility of bulk nanostructured materials 

The limited ductility of bulk nanostructured materials is one of major concerns for the technological applications of the materials, even though the bulk nanostructured materials possess relatively high strength. This talk will first analyze the intrinsic and extrinsic reasons for the low ductility of the bulk nanostructured materials, and then summarize effective strategies for improving the poor ductility of bulk nanostructured materials. Finally I will report our recent successful examples by applying these strategies in nanostructured 7075 Al, NiFe, Ni, etc. to obtain both high strength and ductility.
