Data confidence 85 high
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 effect of electron irradiation on the structure and mechanical properties of 36% Ni, 12% Cr, 3% Ti, 1% Al age-hardened austenitic steel after different modes of thermomechanical treatment, including quenching, rolling with a 99% degree of compression, and aging, is studied experimentally in the constant current mode with a fluence of 1019 freq cm−2. Regularities of the changes in the structural phase composition and mechanical properties of the investigated alloy are established as a result of electron irradiation. Scientifically grounded recommendations are given for selecting modes of thermomechanical treatment, supplemented by irradiation and ensuring the optimum combination of strength and ductility in 36% Ni, 12% Cr, 3% Ti, 1% Al age-hardened austenitic steel.
