By use of X‐ray diffraction, the load‐bearing contributions of nanometer‐thick Cu and Nb layers in Cu/Nb multilayer composites are isolated. The Cu bears higher stresses at failure and the Nb bears lower stresses at failure with decreasing Cu layer thickness. The Cu and Nb layers appear to have independent deformation mechanisms.
