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

METHODS FOR OBTAINING A GRADIENT STRUCTUREThe methods for fabrication of the functionally-gradient materials, which have a high complex of unique mechanical, technological and special properties, when they working on impact, wear, fatigue, experiencing increased cyclic and alternating loads, are reviewed.Considered materials are used in aerospace engineering, energy, and other industries characterized by extremely unfavourable, extreme operating conditions of critical parts, structural elements, and assemblies.Different methods for fabrication of the gradient structures are considered, in particular, the method of severe plastic deformation of metals and the process of active bending of copper.The effect of grain size, texture, and grain-growth gradients on the deformation mechanisms and mechanical properties of gradient-nanostructured nickel, as well as functionally-gradient ceramic materials are studied.The review may be of interest to researchers and scientists in the field of materials science, metallurgy, and nanotechnology.
