Abstract

The microstructure and high temperature mechanical properties of polycrystalline Cu-Nb nanolayered composites prepared by magnetron sputtering were evaluated. Peak tensile strength decreased from ∼450 MPa at 500 °C to ∼150 MPa at 700 °C for 75 nm Cu-75 nm Nb multilayer. Evidences of interlayer sliding upon tensile deformation were detected, but nanolayered structures were stable.
