(a) Sketch a typical eutectic phase diagram, with components A and B having similar melting points. B is much more soluble in A (maximum = 15%) than A is in B (maximum = 5%), and the eutectic composition occurs near 40% B. The eutectic temperature is 2/3 of the melting point. Label the axes of the diagram. Label all the phases. Use α and β to denote the solid phases.
(b) For an overall composition of 60% B, list the sequence of phases found as the liquid is slowly cooled to room temperature.
