Draw the iron-Fe3C phase diagram. Consider 0.4 and 1.1 wt% C steel alloy. It is cooled slowly from a temperature within austenite phase to room temperature. Show a) microstructure at 1000 °C b) microstructure at 730°C  c) microstructure at 715°C and d) microstructure at room temperature   e) determine the phase present, the phase compositions at 715 and 730 °C f) What do you say about mechanical properties of these alloys, depending on their microstructure at room temperature?
