Problem 8 For alloys of two hypothetical metals, A and B, there exist two phases: a is an A-rich phase and B is a B-rich phase. From the mass fractions of both phases for two different alloys shown in the table below, given at the same temperature, determine the composition of the solvus (solubility limit phase boundary) for each phase at this temperature. Alloy Composition Fraction Fraction a Phase B Phase 60 wt% A-40 wt% B 0.57 0.43 30 wt% A-70 wt% B 0.14 0.86 #1 #2
