Mössbauer Investigations of the Chemical States of Tin and Iron Atoms in Zirconium Alloy Oxide Film

Source

The chemical states of tin and iron atoms were investigated by Mössbauer spectroscopy on oxide films (of various thicknesses) formed on a Zr-1.3% Sn-1% Fe-0.5% Cr-0.12% O alloy (enriched with 119Sn and 57Fe) in an autoclave at 633 K with 10 ppm Li and 650 ppm B. Specimens were analyzed by Conversion Electron Mössbauer Spectroscopy (T = 298 K) and γ-ray transmission (T = 298 and 77 K) modes to investigate the surface and the bulk of the oxide films, respectively. The main results on the oxide were as follows: • For tin atoms: Sn2+ and Sn4+were clearly identified. In addition, metallic β-Sn was greatly suspected. • For iron atoms: Zr(Fe,Cr)2 precipitates, α-Fe, Fe3O4, Fe2+, and Fe3+, were clearly detected. Moreover, it was shown that during the oxide film growth the chemical states of tin and iron atoms change, in particular after the kinetic transition.
