Abstract

Here we report the formation of dispersive shear bands in a heterostructured Cu composed of coarse-grained (CG) and ultrafine-grained (UFG) domains. Microscale digital image correlation revealed that dense shear bands evolved in a stable manner over the whole gauge section. Our observation suggests that the limited strain hardening of UFG domains and deformation heterogeneity promoted shear banding, which is a major deformation mechanism in heterostructured materials. The dispersive shear banding helped with ductility retention.
