Unformatted text preview: 1/** Question 2 (25 points): The phase diagram below is used for all parts (a through c) of problem 2. All phases are labeled in boxes. An intermetallic compound is present at 20 wt% Q. Also, P has twice the atomic mass as Q. (2a  12 points total) (2ai  3 points) Draw and label the microstructure that would results from slowly cooling a sample from just above point A to just below point E . Secondary + Primary precipitates (2aii3 points) Which point, C or E , has the highest proportion of ? Show your calculations. Lever Rule: in C: in D: There is a higher proportion of in C. 2/** (2aiii  2 points) In the temperature range shown, what is the maximum solubility of P in Q? At what temperature does this occur? The max solubility is P in Q is approximately 85 Wt% Q which occurs at 0C....
