The introduction of nanoscale coherent twin boundaries (TBs) can be an effective strategy to achieve desirable strength while maintaining substantial ductility and work hardening of metallic materials. In this talk, I will present our recent studies on twin-mediated deformation in metals, including extra strengthening in gradient nanotwinned metals, extreme shear deformability of twin boundary, and twin-mediated dynamic adjustment of GB mobility in nanocrystals.
