Abstract

The Gibbsian interfacial excess of Si (Γsi) is measured at high-angle tilt grain boundaries (GBs) and high-angle twist GBs of an Fe(Si) alloy equilibrated at 823 K; for each GB, transmission electron microscopy is used to determine precisely its five macroscopic geometric degrees of freedom. The value Γsi is ≈ 0.182×1014 atoms cm-2 at the high-angle tilt and twist GBs respectively.
