In a system A-B-C, a ternary alloy of composition 30wt% B and 30 wt % C consists at a particular temperature of three phases of equilibrium compositions as follows:
Liquid phase: 50% A, 40% B, 10% C
Alpha solid solution: 85% A, 10% B, 5% C
Beta Solid solution:10% A, 20% B, 70% C
(a) Calculate the proportions by weight of liquid, Alpha, and Beta present in this alloy.
(b) For the same temperature, deduce the composition of the alloy consisting of equal proportions of Alpha and Beta phases of the compositions stated above, but with no liquid phase.
