Heterostructured materials are an emerging class of materials with unprecedented mechanical properties. In this talk, heterostructured copper and brass laminate and lamella materials are picked as model systems to probe the fundamental deformation mechanisms of heterostructured materials. A particular emphasis is placed on the role of heterostructured interfaces during deformation and how their parameters affect the dislocation accumulation, hardening behavior and, eventually, the strength-ductility. Results show such interfaces strongly influence the geometrically necessary dislocation (GND) evolution and give rise to the so-called hetero-deformation-induced (HDI) hardening. Important implications for optimization of heterostructure design to achieve superior mechanical properties will be discussed.
