Simulation of Thermodesorption of Hydrogen from Titanium Hydride Irradiated by an Ion Beam
<sec> —The study of the behavior of hydrogen in metals and their alloys is of great significance in view of the application of hydrogen—metal systems for the absorption of nuclear radiation, in neutron sources, and for storage of hydrogen. The behavior of hydrogen in titanium hydrides at superhigh concentrations of hydrogen in TiH<sub>2 +</sub> <sub>x</sub> has been simulated in this work using numerical methods of continuum mechanics. A model of diffusion and thermodesorption of hydrogen used in this work involves the structure of the hydrogen sublattice of titanium hydride. The inclusion of the structure of the hydrogen sublattice of β-TiH<sub>x</sub> allows simulation of thermodesorption of hydrogen under the additional introduction of hydrogen by a hydrogen ion beam. </sec>
