Production of nanostructured shape memory alloy for the aerospace industry by rolling method

A technology has been developed for obtaining high-strength nanostructured titanium nickelide by intensive plastic deformation in rolling mills. An alternative to powder metallurgy is proposed a technological solution for obtaining a material with a nanostructure, bypassing the stage of directly obtaining powders and their compacting. Experimental data are obtained and theoretical conclusions are drawn about the relationship between the evolution of the defect structure and the nature of the change in the mechanical properties of titanium nickelide under the influence of intense plastic deformations. The offered technology is realized on the usual industrial equipment without use of special expensive installations. © 2021, Univelt Inc. All rights reserved.
