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...

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 well studied. Herein, the exact chemical composition along the bimetal interface is analyzed by multiple energy-dispersive X-ray spectroscopy line scans. Furthermore, microhardness maps are drawn up based on Vickers microindentations in the same area. Based on these findings, the presence and distribution of intermetallics, as signs of successful welding, are determined, as well as their influence on the mechanical properties of the weld. |
