Study of Hydrogenated Titanium Irradiated with Neutrons by the Methods of Thermally Stimulated Gas Release and Thermopower

Hydrogen desorption from hydrogenated titanium after its irradiation with thermal neutrons is considered. The study was carried out using the methods of thermally stimulated hydrogen release and thermopower. During nuclear transformations in titanium irradiated with neutrons, hydrogen, radioactive vanadium 51V, γ-active isotope 46Sc, γ-quanta with energy from 220 to 1120 keV are formed, depending on the neutron energy. The intensity of γ-radiation depends on the concentration of hydrogen contained in titanium pre-saturated with hydrogen. The presence of γ-radiation should be taken into account when creating neutron protection based on titanium. When intermetallic compounds intended for accumulation and transport of hydrogen are irradiated, there is a loss of titanium atoms and its original stoichiometric composition is disrupted under conditions of hydrogen exit from the irradiation zone. When titanium is irradiated with neutrons, a change in the hydrogen concentration in the samples and a redistribution of hydrogen between the solid solution and the hydride phases of titanium are observed.
