ead-tin (Pb-Sn) is an eutectic type of phase diagram. At 183 °C, liquid (61.9 wt.% Sn), solid tin (97.8 wt.% Sn) and solid 18.3 wt.% Sn) are in equilibrium. Consider a tin wire being welded to a lead substrate. Just at the weld interface, the structure shows 2.4% of a eutectic-like mixture in a Sn matrix. What composition (in terms of wt.% Sn) would you ct to obtain at the weld interface provided you are looking at the interface at a temperature just below the eutectic erature?

The lead-tin (Pb-Sn) is an eutectic type of phase diagram. At 183 °C, liquid (61.9 wt.% Sn), solid tin (97.8 wt.% Sn) and solid lead (18.3 wt.% Sn) are in equilibrium. Consider a tin wire being welded to a lead substrate. Just at the weld interface, the microstructure shows 2.4% of a eutectic-like mixture in a Sn matrix. What composition (in terms of wt.% Sn) would you expect to obtain at the weld interface provided you are looking at the interface at a temperature just below the eutectic temperature? Answer:
