Cementite (or iron carbide) is a compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe 3 C. By weight, it is 6.67% carbon and 93.3% iron. It has an orthorhombic crystal structure.

Iron carbide (Fe 3 C) is often labeled as the uncorroded portion of the steel. It is primarily associated with mild steels having a high carbon content and a ferritic-pearlitic microstructure. During corrosion of such steel, the ferrite phase dissolves and a porous iron carbide network is exposed (see Fig. 7.6 ).

Answer to The iron-iron carbide (Fe-Fe3C) phase diagram is shown in the figure below. Austenite containing 0.4 wt.% of carbon was

Fe3c

It forms directly from the melt in the case of white cast iron. In carbon steel, it either forms from austenite during cooling or from martensite during tempering.
