The interstitial alloy between carbon and iron has a complex phase diagram. A compound, Fe 3 C with the fixed composition Fe-6.7 wt % C bounds one end of this diagram and pure iron the other end. Pure ...

The three components in equilibrium at this temperature are Austenite, g, with the composition Fe - 0.77 wt % C, Ferrite, a ... This is illustrated on the partial phase diagram and shown in the ...
