Abstract

The subject of this paper is the analysis of phase transformation temperatures, specifically liquidus temperature (TL) for steel quality 41Cr4. To calculate the temperatures, 66 different variants of the chemical composition of a given steel grade were compiled. The calculations were performed in the CompuTherm thermodynamic database using the Lever microsegregation model. The resulting temperatures are further supplemented by multiple regression analysis, which considers the dependence on the chemical temperature. The results of the regression analysis are used to design a regression equation to calculate the liquidus temperature. It is clear from the obtained results that the chemical composition of the steel has a significant temperature effect on the change in the calculated values.
