Characterization of bimetallic interface in Cu-Al and Ni-Cu rods cold-welded by ECAP

While cold welding by equal channel angular pressing has already been confirmed to be a viable alternative to join materials that commonly tend to exhibit unwanted brittleness and other heat-induced properties, the exact processes taking place at the interface as well as their effects have not been...
