Grain boundary and interfacial sliding in Cu/Nb nanolaminates

The mechanical properties of two types of laminated Cu/Nb composites (with layer thicknesses in the range of 10–12 mm and 10–18 nm, respectively) are investigated in the temperature range of 773–1073 K. The possibility of the manifestation of grain boundary and interfacial sliding along the internal interfaces of the studied materials is examined.
