Sn pb phase diagram. Tin-Lead Alloy System's Binary Phase Diagram The composition of the eutectic phase pf Sn-Pb alloy can be turned into liquid directly from the solid phase, without going through the solid+liquid phase. Sn-Pb alloys are generally used in electrical and electronic components in today's technology. Conclusion. The assessment of Sn-Pb binary phase diagram is very easy like above. Phase diagram of Ag-Pb-Sn system - ScienceDirect 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].
