Abstract Since carbon is a more intensive grain boundary active element and would replace the impurity at the grain boundary of steels, the grain boundary segregation of the impurity would be controlled by the carbon solubility in a-phase. The alloying elements, decreasing - the carbon solubility, would enhance the impurity segregation at the grain boundary. With this point of view, a new modified Guttmann's model is suggested from which the calculated results are in good agreement with the experimental data in carbon and Cr steels.
