We study the problem of synthesis of zirconium- and Zr–Ti-based alloys with the use of zirconium- and titanium-hydride powders. In the proposed approach, hydrogen plays the role of a temporary alloying admixture to these metals. Hydrogen is evacuated from the materials in the course of heating in vacuum and causes a series of phase transitions activating the processes of sintering and chemical homogenization of powder systems. Then the concentration of hydrogen in synthesized alloys decreases to safe levels. We develop the procedures guaranteeing the formation of microstructurally uniform alloys with small amounts of residual pores. The mechanical properties of these alloys correspond to the properties of the alloys obtained by using conventional technologies.
