Abstract

The structure of deformed semi-finished products (forgings) from titanium alloys of Ti–Al–Zr + 0.15% Ru, Ti–Al–V– Mo + 0.15% Ru, 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, as well as a model of the effect of ruthenium on increasing corrosion resistance of titanium alloys of various classes are presented.
