Abstract

Kink band formation is unexpected in cubic nanocrystalline metals but is found to occur during layer-parallel compression of bulk Cu-Nb nanolaminates produced by the accumulative roll bonding process. This deformation mechanism is strongly length scale dependent and allows for large compressive strains (>25%) at high stresses high stresses (>1GPa) without leading to crack formation.
