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.

吉布斯能量平衡（GEB）概念的模型在等温铁素体形成过程中的转变停滞被重新讨论。已经进行了修改，以考虑到碳重新分布到残余奥氏体中以及在低温下转变的铁素体中碳溶解度增加的问题。原始模型和改进模型都充分描述了早期研究中考虑的合金系统中铁素体形成的转变停滞。然而，本研究中提出的修改对于合理描述Mn含量对中碳钢中相变停滞的影响至关重要，在中碳钢中碳的重新分布影响更大。
