© 2016 Elsevier Ltd Joining of nanostructured metals by conventional processes, such as welding, often destroys the functionality of the material by disrupting its microstructure within the heat-affected zone. We present a lithography-based approach to joining of magnetron sputtered, nano-layered Cu/Nb composites without compromising the integrity of the nano-layered architecture by using a microstructure-preserving lap joint. We characterize the lap joint using scanning electron microscopy and nanoindentation, exploring potential variations in structure and mechanical properties within the parent material, overlap zone, and gap zone. Our work advances future applications of nanocomposite materials by paving the way towards practical, microstructure-preserving methods of joining them.
