报告摘要：Material scientists have been working strenuously to make structural materials that have both high strength and high ductility because high strength allows structural components to carry high load and good ductility is essential to prevent catastrophic failure. However, the combination of high strength and good ductility is rare in coarse-grained materials. In contrast, combined high strength and good ductility have been realized in some nanostructured materials processed by severe plastic deformation. In this presentation, the microstructural evolutions of crystalline metallic materials processed by severe plastic deformation and possible structural mechanisms that would contribute to both high strength and high ductility in the materials will be discussed.
