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 ...

The transition from austenite to phases stable at lower temperatures also takes place when the material is cooled at a constant rate. The diagram illustrates the transition zone (yellow) and also ...

IT is generally accepted that the lattice parameter of retained austenite in quenched iron—carbon alloys increases continuously and linearly with the increase of carbon content. So far ...
