4. Consider the solidification of a binary Pb-10%Sn alloy. Assume that during solidification,
there is complete mixing in the liquid and no diffusion in the solid. Use the phase diagram
below to answer the following question.
(a)
Draw (on the phase diagram) the compositions of the liquid and the solid at the
interface as a function of temperature during solidification.
(b) Illustrate on the phase diagram how one would calculate the volume fraction solidified
at a given temperature.
(c)
(d)
Indicate the temperature at which solidification is complete.
