Question

Refer to Figure 1 showing the phase diagram for the Fe-Fe3C system. Consider 1.0 kg of austenite containing 1.15 wt% C, cooled to below 727 C (1341 F).

What is the proeutectoid phase?
How many kilograms each of total ferrite and cementite form?
How many kilograms each of pearlite and the proeutectoid phase form?
Schematically sketch and label the resulting microstructure.
