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

In this paper the ion-induced structural-phase transformations in austenitic stainless steels 12Cr18Ni10Ti, AISI 316 and AISI 304 have been studied by the Mössbauer spectroscopy of conversion electrons, X-ray diffraction and scanning microscopy. It has been established, that the electronic structure of the Mössbauer atoms in stainless steels AISI 304 and AISI 316 are different. Consequently, molybdenum does not affect the short-range order of 57Fe in AISI 316 steel. Implantation of its own atoms (57Fe) in AISI 316 steel leads, as in case with AISI 304 and 12Cr18Ni10Ti steel, to martensitic transformations. Among three steels AISI 316 was found to be the most stable to the ion-induced structural phase transformations.
