Abstract
The mechanism of hydrogen-induced structure formation in titanium alloys with β-eutectoid stabilizers is analyzed. Additional hydrogen alloying of Ti-Cr alloys is shown to increase the stability of the β phase with respect to the α phase and to decrease its stability with respect to the intermetallic compound TiCr2. Hydrogen dissolved in a commercial multicomponent TS6 alloy containing 11.3% Cr is found to favor the precipitation of an intermetallic compound TixCry, which also contains other alloying elements present in the alloy. The mechanism and kinetics of the formation of this intermetallic compound during hydrogenation annealing and isothermal heat treatment are considered. Structures with the intermetallic compound TixCry can be produced upon low-temperature vacuum annealing of a hydrogen-charged TS6 alloy.
