Examples from the Web for austenite
Austenite may contain carbon in any proportion up to about 2.2%.
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.
- a solid solution of carbon in face-centred-cubic gamma iron, usually existing above 723°C
- the gamma phase of iron, stabilized at low temperatures by the addition of such elements as nickel
