Abstract

AbstractThe structure of deformed semifinished products (forgings) from titanium alloys of Ti–Al–Zr + 0.15% Ru, Ti–Al–V–Mo + 0.15% Ru, and Ti–Al–V–Cr–Fe–Mo + 0.15% Ru systems has been investigated. The basic mechanical properties, microstructure, results of local elemental and phase analyses obtained by X-ray spectral microanalysis and backscattered electron diffraction, and also a model of the effect of ruthenium on increasing corrosion resistance of titanium alloys of various classes are presented.
