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 lattice parameters of martensite and austenite in steels (carbon content varying from 0.57 to 1.74 per cent) have been extensively studied; but considerable discrepancies exist in the values ...

For the hypereutectoid composition shown by the vertical green bar the material enters the two phase austenite + cementite zone prior to cooling through the eutectoid temperature. While it cools ...
