Effect of hydrogen on the deformation development in titanium alloy of the Ti-Al-V system under creep

Аннотация

In this work we investigate the deformation behavior of hydrogenated ultrafine-grained Ti-6Al-4V alloy under creep in the temperature range 723-873 K. The hydrogen presence in the amount of 0.26 wt % in a solid solution is found to lead to a decrease in the rate of steady-state creep and strain to failure and increase in time to failure of Ti-6Al-4V alloy. Possible reasons of a rise in the creep rate and strain to failure of the alloy under creep and simultaneous hydrogen degassing are discussed.
