Formation of alloys in Ti–V system in hydride cycle and synthesis of their hydrides in self-propagating high-temperature synthesis regime

Abstract In the present work, the possibility of formation of titanium and vanadium based alloys of BCC structure using hydride cycle was investigated. The mechanism of formation of alloys in Ti–V system from the powders of hydrides TiH 2 and VH 0.9 (or of V) by compaction followed by dehydrogenation was studied. Then, the interaction of the synthesized alloys with hydrogen in combustion regime (self-propagating high-temperature synthesis, SHS) resulting in hydrides of these alloys was investigated. DTA and DSC analyses of some alloys and their hydrides were performed and their thermal characteristics were measured.
