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.
