10 kg of graphite (C) is added to 990 kg of Fe and the mixture is heated to 1600 C. Slowly cool as follows. a.) Cool to 1400 C. Sketch the morphology. Calculate the mass of each microstructure and the mass and composition of each phase within each microstructure. b.) Cool to 1000 C. Sketch the morphology. Calculate the mass of each microstructure and the mass and composition of each phase within each microstructure. c.) Cool to 728 C. Sketch the morphology. Calculate the mass of each microstructure and the mass and composition of each phase within each microstructure. d.) Cool to 726 C. Sketch the morphology. Calculate the mass of each microstructure and the mass and composition of each phase within each microstructure.
