The Gibbs energy balance (GEB) concept for modeling the transformation stasis during isothermal ferrite formation
is revisited. Modification has been made to take into account the carbon redistribution into remaining
austenite and the increased carbon solubility in ferrite transformed at low temperature. Both the original and
modified models adequately describe the transformation stasis in ferrite formation in alloy systems considered in
earlier studies; however, the modifications proposed in the present study are critical for the reasonable
description of the effect of Mn content on the transformation stasis in a medium carbon steel where the redistribution
of carbon has more significant influence.
