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 experiments studying the peculiarities of changes in both phase composition and mechanical properties of austenitic 12X18H10T stainless steel, unirradiated and irradiated with neutrons, subjected to low-temperature deformation and post-deformation annealings in the temperature range 300–800 °C are discussed. The features of the formation and growth of the martensitic-phase during deformation and annealing are investigated. The dependence of the α´-phase content on microhardness of austenitic steel is considered.
