Аннотация:The chemical structure of Fe78B13Si9 alloy in the solid and liquid states and local atomic environ-
ment are studied in situ by X-ray photoelectron spectroscopy (XPS). The chemical bonds between elements
in the melt are analyzed during a temperature increase. Two temperature regions are identified. The liquid
surface in the first temperature region is shown to contain clusters of Fe–Si and (Fe–Ox)–Si types. In the
second one, clusters of Fe–B and (Fe–Ox)–B types dominate. It is impossible to determine the composition
of the clusters definitively using XPS data only. A jump-like change in the composition of the surface layers
of the melt is detected, which is interpreted as structural transformations within the liquid state.
