For the metals A and B, which are given below, create the hypothetical phase diagram between 500 ° C and 900 ° C temperatures. The melting temperature of metal A is 840 ° C. The solubility of B in A can be ignored at all temperatures. Metal B has a melting temperature of 730 ° C. The maximum resolution of A in B is 10 wt% A, which occurs at 600 ° C. At 500 ° C, the solubility of A in B is 6% A by weight. A eutectic 600 ° C and 74% B by weight - 26% by weight A are formed. The second eutectic occurs at 630 ° C and 59% B - 41% A by weight. A third eutectic occurs at 655 ° C and 39% B - 61% A by weight. A congress melting point is formed at 680 ° C and 52% B - 48% A by weight. A second congress melting point is formed at 655 ° C and 66% B - 34% A by weight. The intermetallic compound AB is present at 52 wt% B - 48 wt% A. The intermetallic compound AB2 is present at 66 wt% B to 34 wt% A.
