Abstract

The α + β dual-phase titanium alloy, Ti-6Al-4V, was thermohydrogen processed with 0.1, 0.3 and 0.5 wt% hydrogen. Effect of hydrogenation on microstructure and mechanical properties of Ti-6Al-4V titanium alloy was systematically discussed. It was found that hydrogen stabled the β phase and leaded to the formation of α′ martensite as well as δ hydride in the hydrogenated titanium alloy. Mechanical properties of hydrogenated titanium alloy deteriorated with increasing hydrogenation content. The mechanism of hydrogen-induced microstructure/mechanical properties modification in Ti-6Al-4V alloy was elucidated.
