The face-centred high-temperature phase of steel

Austenite is the face-centred-cubic phase of iron and steel (also called gamma iron), stable at high temperature, that can dissolve far more carbon than the room-temperature phases and is the structure from which steels are hardened: on cooling it transforms into ferrite, pearlite, bainite, or, if quenched fast, martensite, and the route taken sets the steel's properties. Some austenite can be retained at room temperature. Bhadeshia and Honeycombe's Steels: Microstructure and properties treats austenite and the transformations it undergoes. The referent is a crystallographic phase defined by its structure, carbon solubility, and transformation behaviour.[1]
