Simulation of Thermal Desorption of Hydrogen from Titanium Hydride under the Influence of an Ion Beam

Abstract

The behavior of hydrogen in metals and their alloys is of great interest, since hydrogen–metal systems are used in practice for absorption of nuclear radiation, in neutron sources, and for hydrogen storage. This study is focused on simulation of the behavior of hydrogen in titanium hydrides at ultrahigh concentrations of H in TiH_{2 + x}. Numerical methods of continuum mechanics are used. The structure of the hydrogen sublattice of titanium hydride is taken into account in the model of diffusion and thermal desorption of H. This makes it possible to model the thermal desorption of hydrogen under irradiation with a beam of hydrogen ions.
