Nоte: Shоw yоur cаlculаtions cleаrly on the paper and show your work clearly on the graph or else you will lose points! Given the phase diagram below: a) Redraw/highlight the eutectic line and write down the eutectic temperature. b) Fill in blank the phase fields using common nomenclature (liquid; a, b, g, d, etc. for solid phases). Mark eutectic point determine eutectic temperature and write the eutectic reaction. c) At 75 wt. % B, and starting from 100% liquid, at what temperature would the material first begin to solidify? At what temperature would the material be entirely solid? d) At 75 wt. % B, indicate on the phase diagram what phases are present at 625 ºC. To the best of your ability, estimate the composition of all of the phases present at 625 ºC. Which of the phases present at 625 ºC has the highest fraction? (show your calculations in detail) e) Using the answers that you find in d, calculate the densities of the phases present. (Densities of phases A and B are 8.96 g/cm3 and 7.13 g/cm3 respectively)
