Question:Construct the hypothetical phase diagram for metals A and B between room temperature (20°C) and 700°C given the following information: The melting temperature of metal A is 480°C. The maximum solubility of B in A is 4 wt% B, which occurs at 420°C. The solubility of B in A at room temperature is 0 wt% B. One eutectic occurs at 420°C and 18 wt% B–82 wt% A. A second eutectic occurs at 475°C and 42 wt% B–58 wt% A. The intermetallic compound AB exists at a composition of 30 wt% B–70 wt% A, and melts congruently at 525°C. The melting temperature of metal B is 600°C. The maximum solubility of A in B is 13 wt% A, which occurs at 475°C. ● The solubility of A in B at room temperature is 3 wt% A.
