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

The results of the short-term thermal tests of SFA samples in the temperature range 450–900 °C are presented. The dependences of the formation of the corrosion layer of the SFA material on the temperature of thermal tests are determined by various ways. It was found that with an increase in the temperature of isochronous exposure above 750 °C, a noticeable discrepancy appears between the dependencies determined by various methods, due to the occurrence of uneven (localized) corrosion.
