Austenite may contain carbon in any proportion up to about 2.2%.
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 first particles of austenite to freeze contain about 0.33% of carbon (p).
The white-hot, solid, but soft mass is now a conglomerate of “primary” austenite, “eutectic” austenite and “eutectic” cementite.
