摘要

Abstract

BSTRACTNanostructured (NS) metals typically fail soon after yielding

starting with the formation of narrow shear bands. Here we report the observation of shear band delocalization in gradient metals. Shear bands were nucleated and delocalized in the NS layers by propagating along the gage length soon after yielding

converting the shear band into a localized strain zone (LSZ). Synergistic work hardening was developed in the LSZ by regaining dislocation hardening capability

and by back-stress hardening from the strain gradients in the axial and depth directions

which helped with enhancing global ductility.
