Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Mössbauer spectroscopy at 119 Sn and 57 Fe nuclei was used to study thermally induced processes of phase formation in two-layered systems Sn(4 μm)-Fe(10 μm) obtained by ion-plasma deposition. The layered systems were subjected to sequential isothermal annealings at 550°C and 700°C to show the formation of intermetallic compounds FeSn and Fe 3 Sn 2 and of an α-Fe(Sn) solid solution. It has also been shown that the nature of the phase transformations is determined by a change in the local concentration of tin in the sample in the process of diffusion of the atomic components. Thermally stable spatially inhomogeneous systems FeSn/α-Fe(Sn) and Fe 3 Sn 2 /α-Fe(Sn) have been obtained.
