| Outline of Final Research Achievements |
We figured out underlying universal mechanisms, which dominate the unusual mechanical properties of bulk nanostructured metals, using first principles density functional theory and multiscale atomistic simulation methods. Based on the clarified universal mechanism, we proposed a model that can predictively describe the mechanical properties of bulk nanostructured metals. Moreover, in the model constructing process, we newly obtained details of electronic, atomistic and thermodynamic understandings for individual unit processes that governing the mechanical properties, such as grain boundary decohesion, grain boundary diffusion, grain boundary motion, and dislocation nucleation from grain boundary.
