Abstract

Comparative studies of the effect of hydrogenation on creep regularities of the titanium alloy of the Ti-Al-V system in the fine-grained (dav ≈ 7 µm) and ultrafine-grained (dav ≈ 0.3 µm) states are performed for the creep rates in the interval 10-7-10-5 s-1 at temperatures in the range 723-823 K. Hydrogenation of the alloy to 0.23 wt. % is found to lead to a decrease in the steady creep rate and increase in the time to failure with simultaneous decrease in the value of deformation to failure. Possible reasons for the violation of the creep power law for the hydrogenated alloy are discussed.
