Effect of Hydrogen on Alpha Titanium Alloy

Abstract

The effect of up to 200 ppm hydrogen on the microstructure and mechanical properties of high-purity titanium containing oxygen, nitrogen, tin, and aluminum was investigated. Increasing the hydrogen content resulted in precipitation of a hydride phase and decreased the notch-bend impact strength of the alloys containing oxygen, nitrogen, and tin, similar to the hydrogen embrittlement of unalloyed high-purity titanium. No hydride precipitation or significant embrittlement of the Ti-5AI alloy was found with up to 180 ppm hydrogen.
