Abstract
Experimental tests of flat titanium samples at a temperature of 450 °C, stretched with a constant force up to destruction, were carried out. Titanium samples were hydrogenated in the Moscow Aviation Institute laboratory to a hydrogen content of 0.1 %, 0.3 % and 0.6 % by weight of the specimen, and then tested in the laboratory of Lomonosov Moscow State University. From the experiments, the time to failure, the localization time of the deformations, and the stress distribution along the longitudinal coordinate of the sample over time were obtained. A metallographic study was conducted and the phase composition was investigated in Moscow Aviation Institute. The effect of hydrogen on long-term strength, mechanical characteristics, and phase composition has been elucidated.
