A 10 30 70 1) For an A-B alloy of composition 25 wt% B (i) Draw the microstructure at T (just above the eutectoid temperature) and calculate the fraction of each phase in the microstructure. (ii) Draw the microstructure at T (just below the eutectoid temperature) and determine the amount of each phase, i.e., fraction of proeutectoid alpha, eutectoid alpha and eutectoid beta. 2) Provide a brief summary of phase transformations which are often observed in the iron-carbon alloy system due to various heat treatment procedures carried out to tune the microstructure. Compare mechanical strength and ductility of the materials/microstructures that form as a result of such heat treatment processes.
