(Solved): Consider the hypothetical eutectic phase diagram for metals A and B between 200 degrees C and 1200 d ...

Below is shown a hypothetical phase diagram for metals $A$ and $B$ between $200^{?}\mathrm{C}$ and $1200^{?}\mathrm{C}$. Which of the following statements are correct? (Chnnce all that annly) A eutectic occurs at $550^{?}\mathrm{C}$ and 35 wt $\%$ B- 65 wt $\%$ A. The solubility of $A$ in $B$ is negligible at all temperatures. The solubility of $B$ in $A$ is not negligible at all temperatures. The melting temperature of metal $B$ is $570^{?}\mathrm{C}$. A eutectic occurs at $450^{?}\mathrm{C}$ and 90 wt $\%$ B-10 wt $\%$ A. The melting temperature of metal $A$ is $1075^{?}\mathrm{C}$. The intermetallic compound $AB$ exists at a composition of $70\mathrm{wt}\%\mathrm{B}?30\mathrm{wt}\%\mathrm{A}$, and melts congruently at $725^{?}\mathrm{C}$.
