. . . . 1: Construct the hypothetical phase diagram for metal A and B between temperature of 600 C and 1000 C given the following information: The melting point of A is 940 C. The solubility of B in A is negligible at all temperatures The melting point of metal B is 830 C. The maximum solubility of A in B is 12A, which occurs at 700 C. At 600 C, the solubility of A in B is 8%A. One eutectic occurs at 700 C and 75%B. w A second eutectic occurs at 730 C and 60%B. A third eutectic occurs at 755 C and 40%B. One congruent melting point occurs at 780 C and 51%B. A second congruent melting point occurs at 755 C and 67B. There exist two intermetallic compounds: AB at 51%B and AB2 at 67B. Note all composition are in weight percent. . . SIEN
