Question

Consider 1 kg of a Pb-Sn alloy with 50 wt % Sn. The alloy is heated to 400o

(a) Upon cooling, at what temperature will the first solid appear, what is the phase of the first solid, and what is its composition?

(b) At 200oC, you have a mixture of solid and liquid phase; the amount of the solid phase is ____ the amount of the liquid phase

(c) At 150oC, you will get an alloy with two solid phases, a-Pb and b-Sn. The amount of the a-Pb solid phase is ____ the amount of b-Sn solid phase?
