Ferrites are ferromagnetic ceramic materials, compounds of iron, boron and barium, or strontium and molybdenum. A ferrite material has a high magnetic permeability, which allows it to store stronger ...

The eutectoid phase transition in the iron carbon system takes place at 727 C. The three components in equilibrium at this temperature are Austenite, g, with the composition Fe - 0.77 wt % C, Ferrite, ...

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 ...
