(a) An alloy of two metals A and B is in the composition 40 wt% B and 60 wt% A. At certain temperature T, it consists of 66 wt% a-phase and 34 wt% of ß-phase. The a-phase has the composition 13 wt% B and 87 wt% A. Find the composition of the B-phase. (b) Construct the hypothetical phase diagram for metals A and B between temperatures of 600 °C and 1000 °C given the following information: • The melting temperature of metal A is 940 °C. • The solubility of B in A is negligible at all temperatures. • The melting temperature of metal B is 830 °C.
