Features of Metallurgy of Titanium Hydride-Forming Alloys

The article considers various aspects of metallurgical technologies to produce high-quality titanium-containing metal hydride (MH) alloys of the AB-, AB2- and BCC-types with the prospect of developing foundations of their industrial-scale production using feedstock available in the Russian Federation, including a cheap mineral, ilmenite (FeO·TiO2). The technologies of vacuum induction melting (VIM), vacuum arc melting (VAM) and self-propagating high temperature synthesis (SHS) were investigated and optimized. Dependence of the oxygen content, as the most harmful admixture for AB-type MH alloys, on the technological parameters of their preparation was constructed. The article also presents the data on the phase composition and hydrogen sorption performance of the selected titanium-containing alloys prepared by the developed technology.
