For alloys of two hypothetical metals A and B, there exist the, A-rich phase and a , Brich phase. From mass fractions of both phases for two different alloys given in following table (which are at same temperature), find out composition of phase boundary (or solubility limit) for both and phases at this temperature.
Alloy Composition Fraction Fraction
Phase Phase
60 wt% A-40 wt% B 0.57 0.43
30 wt% A-70 wt% B 0.14 0.86
