Lastly, there is a definite compound of iron and carbon, iron carbide or cementite, having the formula Fe3C.The Phase Rule and Its Applications
Here the mass consists of primary austenite, eutectic austenite and cementite interstratified and pro-eutectoid cementite.
Ferrite and cementite, already described in 10, are the final products of the transformation of austenite in slow-cooling.
The white-hot, solid, but soft mass is now a conglomerate of “primary” austenite, “eutectic” austenite and “eutectic” cementite.
