Webthe ferrite and austenite, but subject to that constraint, the carbon redistributes until it has the same chemical potential in both phases. Therefore, the tie–lines in the phase diagram (Fig. 5) are all virtually parallel to the carbon axis, since Mn does not partition between ferrite and austenite.

WebThis can be illustrated by a continuous cooling transformation (CCT) diagram which plots the time required to form a phase when a sample is cooled at a specific rate thus showing regions in time-temperature space from which the expected phase fractions can be deduced for a given thermal cycle. WebOn the phase diagram it is clear that at 1130 °C austenite can contain 1.7% carbon as solute, well above the carbon levels of steels. Ferrite, while less dense than austenite, has no such locations for carbon solute, and the maximum solubility of carbon in α ferrite is only 0.035% at 732 °C.
