Grain boundary segregation of antimony in α-iron: prediction and experimental data

Abstract

A method recently proposed to predict segregation of any element at any grain boundary in a given matrix is briefly outlined. Besides a large success in comparison of predicted and experimental data, there seem to be substantial discrepancies in some cases such as segregation of antimony in α-iron. In this paper, we show that the discrepancy in this case originates in incomplete correlation of experimental data: if the grain boundary saturation is taken into account, a good agreement between experiment and prediction is obtained.
