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 structural-phase state in the zone of localization of plastic deformation of the titanium-aluminum composite subjected to high-speed shock load was studied. A sinusoidal nature of the deformation of the boundary of the composite layers beyond the shear strain band, indicating the localization of plastic deformation waves in the stress concentration zone, is revealed. It is shown that the main phase forming in the zone of localization of plastic deformation is the atomically ordered metastable phase Al3Ti, with the structure Pm3m
