Question: For a 40-60 Pb-Sn solder, find ; a) Phase present, Composition of phases and Weight fraction at 200˚C b) Phase present, Composition of phases and Weight fraction at 100˚C 4. Phase Diagram: 5. In the Pb-Sn phase diagram below, there are 6 phase fields: three shaded purple and three shaded white. The three purple phases fields are single phase regions, regions in which only one phase exists, and the white phase fields are two-phase regions.

The (Sn) phase is the primary phase in all cases. Under Scheil conditions the alloy Sn-.04Bi-.06Pb encounters the L -> (Sn) + (Pb) monovariant eutectic where both phases form simultaneously from the liquid phase. The path encounters then the four phase reaction, L + (Pb) -> (Sn) + epsilon. Under Scheil assumptions fraction and concentration ... Important: This is a simplified version of the real tin-lead phase diagram.In particular, it ignores the formation of solid solutions of tin and lead. You will find the correct diagram on this NIST web page.Beware that on that page, the tin-lead axis is reversed from the one I have drawn above - in other words 100% lead is on the right rather than the left. 9.38 On the basis of the photomicrograph (i.e., the relative amounts of the microconstituents) for the lead- tin alloy shown in Figure 9.17 and the Pb-Sn phase diagram (Figure 9.8), estimate the composition of the alloy, and then compare this estimate with the composition given in the figure legend of Figure 9.17.

The study of ternary Ag-Pb-Sn phase diagram is important e.g. for the soldering industry. Pb-Sn alloys have been used as solders for a long time [1,2]. Even though the eutectic Pb-Sn has been prohibited from use in electronic products since 2006 [3], Pb-Sn alloys with Pb content higher than 85% are still in use [4].
