Question: For alloys of two hypothetical metals A and B, there exist

For alloys of two hypothetical metals A and B, there exist an a, A-rich phase and a B, B-rich phase. From the mass fractions of both phases for two different alloys (given below), which are at the same temperature, determine the composition of the phase boundary (or solubility limit) for the following: Alloy Composition 60 wt% A-40 wt%B 30 wt% A-70 wt%B Fraction Fraction a Phase B Phase 0.56 0.44 0.16 0.84 (a) a phase i 85.53 wt% A (b) ß phase 21.725 wt% A
