The structure has face-centered cubic symmetry, and is a little heavy to understand. The general formula is AB 2 O 4. The oxygens form an fcc lattice. The A cations occupy tetrahedral holes, and the B ...

The transition that determines the micro-structure of the alloy is a solid-state process: Austenite <-> Ferrite + Cementite Austenite is stable above 727 C and is an interstitial solid solution of ...
