摘要：
The alpha + beta 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 beta phase and leaded to the formation of alpha' martensite as well as delta 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.
