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 paper presents the results of mechanical tests to determine changes in the strength characteristics of the material of zirconium alloy E125 after local thermal exposure. Dependences of the strength characteristics of the material of the E125 alloy on the hardness are determined. The maximum and minimum values of strength in the zones of reflow and heat exposure have been determined. An assessment of the change in the geometric parameters and the hardness of the heat- affected spot from the modes of arc action and the conditions of subsequent cooling is carried out.
