Interface structure plays a vital role in plasticity of metallic nanolayered composites (MNCs). In this work, we explore the effects of thick three-dimensional (3D) interface structures on deformation behavior of Cu/Nb MNCs by using molecular dynamics simulation. Our analysis reveals that the 3D interface structure is crystalline dominant rather than amorphous and dislocations are distributed on multiple slip planes within the 3D interface region. The effect of layer thickness on the strength of MNCs has been suppressed by the 3D interface structure, which can also inhibit shear band formation.
