摘要：

TG/DSC tests of non-hydrogenated and hydrogenated Ti-6Al-4V alloys were carried out in order to investigate the dehydrogenation behavior of hydrogenated titanium alloys. Results indicate that mass losses of the hydrogenated Ti-6Al-4V alloys are significantly different with that of the non-hydrogenated Ti-6Al-4V alloy when the heating temperature is higher than 600 ℃. Mass loss of the hydrogenated Ti-6Al-4V alloy increases with the increasing of hydrogen content when the heating temperature is in the range of 600 ℃ to 900 ℃ due to the decomposition of metastable phases. The maximum mass loss of the hydrogenated Ti-6Al-4V alloy is in correspondence with its hydrogen content upon no consideration of oxidation. The optimal dehydrogenation temperature among hydrogenated Ti-6Al-4V alloys is 750 ℃. The dehydrogenation process for all hydrogenated Ti-6Al-4V alloys is the same.
