You want to manufacture a low-carbon steel containing 0.03 wt% of cementite when cooled to room temperature. Determine:
(a). The amount of carbon that has to be alloyed with the iron to give this composition.
(b). The fractions of pearlite and the proeutectoid cementite.
(c). The fraction of the eutectoid cementite.
(d). Using dot points and sketches describe what happens to the system as the liquid is cooled from 1600 o C to around 750 o C.
Note: proeutectoid cementite is cementite that is formed above the eutectoid temperature (i.e. in the gamma + cementite phase).
