Question

Answer the following question based on the Lead-Tin binary equilibrium phase diagram shown below (show all your work):

a) 300 kg of pure Tin was added to a melting pot containing 700 kg of pure Lead. The two metals were completly melted and stirred to achieve uniform composition at the liquid state. (Assuming no wastage of metals during melting). Mark the composition of the alloy formed at 150oC in the phase diagram.

b) What phases are present in the alloy at 150oC?

c) What is the composition of each phase at 150oC?

d) What is the mass fraction of each phase at 150oC?

327°C 200 100 (Pb) 20 18.3 20 40 Composition (at% Sn) 60 80 Liquid 183°C 61.9 40 Composition (wt% Sn) 100 600 500 232 C 400 97.8 300 200 100 100 (Sn)
