Abstract

This paper reports the recent results of a transmission electron microscopy study of cold-welded and e-beam deposited Au-Ag interfaces. Dust particles were observed to be embedded between the cold-welded interfaces. These are shown to amplify the defect regions caused by surface asperities. Electron energy loss spectroscopy (EELS) analysis revealed that there was no significant diffusion zone across the cold welding interface. However, sub-micron mechanical twining structures were revealed by transmission electron microscopy (TEM) analyses. These were found to penetrate through both the cold-welded and control Au-Ag interfaces, but with different orientations.
