| Abstract Scope |
Heterostructured (HS) materials are found to possess unprecedented strength and ductility that are not accessible to their homogeneous counterparts. These superior mechanical properties are often not explainable using our textbook knowledge. They are derived from strain partitioning, which result in hetero deformation induced (HDI) strengthening and HDI strain hardening. The HDI stress is produced by the interactive coupling of back stress and forward stress, which can be measured using a loading-unloading-reloading (LUR) method. In addition, heterostructured materials are prone to dispersive strain banding during deformation, which needs to be further studied to probe their formation mechanisms. |
