8. (i) (6 points) According to the phase diagram shown below, label all the two-phase regions on the diagram below. Identify the eutectic and peritectic point in the diagram. At

the eutectic point, what temperature does the last liquid remaining? What would be the microstructure after it fully solidifies (sketch the microstructure and label the phase on it)? (ii) (4 points) In a ternary phase diagram, according to the representation of the mole fractions we discussed in class, show that along the line joining an apex (Z) and a point (P toP') on the opposite side, the ratio of two of the mole fractions remain constant while mole fraction of the third component changes.
