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

It is shown that the process of-phase particles dissolution in the alloy matrix is faster at superplastic deformation than during annealing. Identify ways of 40CrNiAl alloy strengthening treatments after superplastic deformation were determined. Use after superplastic deformation re-quenching and aging leads to an effective hardening of 40CrNiAl alloy. In grains of-matrix allocated secondary lamellae of-phase intermittent mechanism.
