Deformation-induced dissolution of the intermetallic compound FeSn in nanocrystalline [alpha]-Fe

Deformation-induced dissolution of the intermetallic compound FeSn in nanocrystalline [alpha]-Fe

The structure and phase transformations during the mechanical treatment of an α-Fe^sub 98^Sn^sub 2^/FeSn mixture with a total Sn content of 14 at % in a ball planetary mill are studied by X-ray diffraction and ^sup 57^Fe and ^sup 119^Sn Mössbauer spectroscopy. Three stages of the dissolution of the...

Zusammenfassung:The structure and phase transformations during the mechanical treatment of an α-Fe^sub 98^Sn^sub 2^/FeSn mixture with a total Sn content of 14 at % in a ball planetary mill are studied by X-ray diffraction and ^sup 57^Fe and ^sup 119^Sn Mössbauer spectroscopy. Three stages of the dissolution of the intermetallic compound FeSn are found. The key role of a nanostructure with a grain size of ≤10 nm in this dissolution is shown, and a mechanism for its realization is proposed.[PUBLICATION ABSTRACT]
