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

Abstract The layered Zr(2 μm)-Fe(10 μm), Sn(4 μm)-Fe(10 μm) and Sn(4 μm)-Zr(2 μm)-Fe(10 μm) systems subjected to isochronous annealings have been studied. The sequence of phase transformations is determined. In the three-layer system, the formation of intermetallic compounds with a high content of Zirconium and a solid solution α-Fe(Sn, Zr) is established. The spectra of 57Fe nuclei in Iron-based alloys of various concentrations were calculated. A comparison with the experimental spectra of the layered systems obtained by ion-plasma deposition of Tin and Zirconium on an armco iron substrate and subjected to thermal annealing at 750 °C showed a good correlation.
