In this study equilibrium segregation was measured by x-ray microanalysis in an AEM and related to boundary character and structure. Equilibrium segregation of antimony in an austenitic stainless steel was investigated by x-ray microanalysis. Fractional monolayer coverages of antimony were detected at grain boundaries, as well as nickel enrichment and chromium depletion. Equilibrium segregation depends on boundary character. The measured apparent compositions are corrected for the relative spatial extents of the segregant layer and the excited volume. Segregation of antimony to boundary dislocations depends on dislocation character. Alloy composition (in atomic percent) was 68.1 Fe, 16.1 Cr, 14.2 Ni, 0.79 Si, 0.46 Sb, 0.20 Mn, and 0.12.
