• A novel technique is suggested for synthesis of refractory metal alloys by dehydrogenation of compacted mixtures of transition metal hydrides. This technique is applicable to preparation of not only binary but also multi-component alloys, intermetallics, and alloys of III, IV, V, and VIII Group metals with various additives. In this work, the results of detailed investigation on the conditions for formation of Ti-Zr-Hf triple alloys from the TiH 2 , ZrH 2 , and HfH 2 are presented. The alloy structure was found to depend on the ratio of components in a green charge. The triple alloys containing the α- and ω-phases have been prepared. Demonstrated was the ability of Ti-Zr-Hf triple alloys to undergo reaction with hydrogen in a combustion mode yielding respective hydrides.
