Abstract
Phosphorus grain boundary segregation in three polycrystalline Cr-Mo-V low- alloy steels was investigated using Anger electron spectroscopy and thermod ynamic calculations. Obtained data on polycrystals fit very well with the r ecently reported linear relationship between enthalpy and entropy of phosph orus segregation at individual grain boundaries of alpha-iron found in bicr ystals of an Fe-Si alloy. Different crystallography seems to be responsible for the scatter of the values of segregation enthalpy for individual low-a lloy steels. Copyright (C) 2000 John Wiley & Sons, Ltd.
