provide the iron-carbon phase diagram, and then calculate the
amount of the proeutectoid phase and the amount of the pearlite
microstructure expected for your steel ‘s heat treatment. State
exactly which of your microstructures should have the pearlite
microstructure, and then discuss whether your calculated percentage
seems to approximately match what is visible in the appropriate
photographs. Discuss the differences.
