B、 Questions: 1. Question for Classical Nucleation (10%) The free-energy vs. composition curves at 700 °C for an A-B binary alloy are shown in Fig. 1. Consider the two alloys of A-70 and A-80% B. The precipitates were spherical and coherent to nucleate at 700 °C. Ignoring the coherency-strain effect, and assuming the interfacial free energy ($\gamma$ = 200 erg/cm²) for both nuclei with their equilibrium compositions, determine the ratio of A atoms in $\alpha$ nuclei of critical size (i.e., n*A-70B/n*A-80B)

As you work through the following exercise, consider how you are using the Mathematical Practices and the problem-solving process. Suppose you have a dart board similar to the one in Investigation 1.1g. You throw four darts, all of which land on the dart board shown below. 1369 A dart board has a circle surrounded by three outer rings. The inner circle, colored white, is labeled 9. The first surrounding ring, colored blue, is labeled 6. The second surrounding ring, colored white, is labeled 3. The third surrounding ring, colored blue, is labeled 1. List all possible scores from 1 to 36. (Enter your answers as a comma-separated list.)
