Low carbon steel alloys have a composition close to the Eutectoid composition: Fe - 0.77 wt% C. The transition that determines the micro-structure of the alloy is a solid-state process: Austenite <-> ...

Changing the carbon content of the ... however the proeutectoid ferrite is stable and remains in the final polycrystalline material. This is illustrated on the phase diagram and shown in the ...
