MSE 3050, Phase Diagrams and Kinetics, Leonid Zhigilei homework #1 (page 1 out of 2) 1. Calculate the molar enthalpy of pu re i ron a t 1500 K and one atmosphere pressure. The molar heats of phase transformations for iron are: ' H DoJ = 670 J/mol; ' H JoG = 840 J/mol; ' H Go liquid = 13770 J/mol. The constant pressure heat capacities of different phases of pure iron are: c P D = 17.5 + 24.8 u 10 -3 T J/mol K c P J = 35.5 J/mol K c P G = 43.9 J/mol K c P liquid = 41.84 J/mol K Use the phase diagram to estimate the temperatures of phase transformations at 1 atm (or find an accurate value in a reference book) Plot schematically enthalpy vs temperature at one atmosphere pressure
