Construct the hypothetical phase diagram for metals A and B between temperatures of 600C and 1000C given
Question:
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.
● The maximum solubility of A in B is 12 wt% A, which occurs at 700°C.
● At 600°C, the solubility of A in B is 8 wt% A.
● One eutectic occurs at 700°C and 75 wt% B–25 wt% A.
● A second eutectic occurs at 730°C and 60 wt% B–40 wt% A.
● A third eutectic occurs at 755°C and 40 wt% B–60 wt% A.
● One congruent melting point occurs at 780°C and 51 wt% B–49 wt% A.
● A second congruent melting point occurs at 755°C and 67 wt% B–33 wt% A.
● The intermetallic compound AB exists at 51 wt% B–49 wt% A.
● The intermetallic compound AB2 exists at 67 wt% B–33 wt% A.
