WebWe know that intermetallic compound exists as a line on the phase diagram - not an area. Dental amalgams typically use Ag-Sn alloys. If the intermetallic compound is identified as Ag3Sn. You would expect the line location on the AgSn phase diagram at a) 52.4 wt% Ag b) 26.8 wt% Ag c) 52.4 wt% Sn d) 26.8 wt% Sn WebIt was found that bulk Ag 3 Sn intermetallic compounds (IMCs) separated out only in the slowly cooled Sn-4.0Ag solder. This would be explained by the strong kinetic undercooling, arising from the rapid cooling conditions, which leads to the actual eutectic point shifts in the direction of higher Ag concentration.
