Some steels are affected by a phenomenon called the second ductility minimum, which typically occurs between 600 °C and 1000 °C. Understanding and predicting this loss of deformability has been of great interest for researchers around the world. One of the mechanisms controlling the ductility at higher temperatures is the formation of precipitates during the cooling process. The material simulation package MatCalc is utilized to calculate the equilibrium diagrams and phase fractions of the relevant precipitates and the results are compared to experimental data on the same steel grades taken from literature, which have been gathered on a Gleeble thermo-mechanical testing machine. It is shown that a good agreement can be found and that this approach can be utilized to predict the onset of ductility loss during the production process.
