please help. its urgent n ง 2 Below is shown a hypothetical phase diagram for metals A and B between 200°C and 1200°C. Which of the following statements are correct? (Choose all that apply.) 1200 1075°C Temperature (°C) 1000 800 600 400 (A) 570°C L 550°C 65 450°C AB (B) 2000 20 40 60 80 100 (A) Composition (wt% B) -725°C (B) The intermetallic compound AB exists at a composition of 70 wt% B-30 wt% A, and melts congruently at 725°C. The solubility of A in B is negligible at all temperatures. The melting temperature of metal A is 1075°C. The solubility of B in A is not negligible at all temperatures. A eutectic occurs at 450°C and 90 wt% B-10 wt% A. The melting temperature of metal B is 570°C. A eutectic occurs at 550°C and 35 wt% B-65 wt% A.
