Abstract

The wide use of titanium alloys is limited by high costs of both their producing technology and processing. The expansion of area of their application depends on development of more efficient, resource-saving, economical methods providing reduction in the cost of titanium alloys and titanium made products. The hydride cycle (HC) method for synthesis of binary and multicomponent refractory alloys and hydrides can be suitable alternative to traditional metallurgy for production of the alloy in small quantities (small-sized products for technical/medical purposes). This work presents the results of study on the mechanism of Ti–6Al–4V alloy formation in HC. The synthesis parameters are evaluated and optimized. The physicochemical, structural and hydrogen-sorption characteristics of the alloy samples are described. Actually, a resource-saving, efficient technology for synthesis of Ti–6Al–4V alloy by HC is developed and proposed. The synthesized alloy interaction with hydrogen in Self-Propagating High-Temperature Synthesis mode was investigated.
