SOLVED: In the eutectic system A-B, the compositions of the three conjugate phases of the eutectic are α = 15%, L (liquid) = 75% B, and β = 95% B. Suppose that an alloy composed of equal parts of A and B underwent equilibrium freezing to a temperature infinitesimally below that of the eutectic and then rapidly quenched.1) Compute the percentage of primary α and eutectic β.2) Compute the percentage of total α and β.Element A melts at 800°C; B melts at 700°C; and the eutectic melts congrue

In the accompanying eutectic equilibrium phase diagram of temperature versus mole fraction of B for the A-B system shown, note that the pressure for the diagram is constant at 1  atm. Consider an alloy containing 40 wt % of B. In the table, indicate which of the phases are present in the 40 % alloy and give the composition of each (xB) and the fraction present of each for the temperatures shown.
