Structure and Property of Interfaces in ARB Cu/Nb Laminated Composites

Bulk Cu/Nb multilayered composites with high interfacial content have been synthesized via the accumulative roll bonding (ARB) method. Experimental characterization shows that these multilayers with submicronmeter and nanometer individual layer thicknesses contain a predominant, steady-state interface with the Kurdjumov-Sachs orientation relationship joining the mutual {112} planes of Cu and Nb. In this article, we overview microscopy and simulation results on the structure of this interface at an atomic level and its influence on interface properties, such as interface shear resistance and its ability to absorb point defects and nucleate dislocations nucleation.
