Abstract
Homogeneous 12 wt. % gold and 88 wt. % silver alloy wires were sintered at different temperatures for different lengths of time. The cross-sections of the necks between the wires were examined with the help of an electron microprobe to determine the concentration at different parts in and adjacent to the neck. From the concentration profile it was concluded that the initial neck growth as well as segregation takes place by surface diffusion. Peak concentration at the apex of the neck is obtained after sintering 10 minutes at 802°C. At longer times, back diffusion occurs by a combination of surface and volume diffusion and after one hour at 802°C, the samples are homogeneous once again.
