“…Some particular problems of the hydrogen materials science related to the topic of this study were presented and investigated in [14][15][16][17][18][19][20][21][22][23]. This work is a continuation of [24][25][26][27], where the results of modelling hydrogen thermal desorption under various limiting factors are presented.…”

One of the technological challenges for hydrogen materials science is the currently active search for structural materials with important applications (including the ITER project and gas-separation plants). One had to estimate the parameters of diffusion and sorption to numerically model the different scenarios and experimental conditions of the material usage (including extreme ones). The article presents boundary value problems of hydrogen permeability and thermal desorption with dynamical boundary conditions. A numerical method is developed for TDS spectrum simulation, where only integration of a nonlinear system of low order ordinary differential equations is required. The main final output of the article is a noise-resistant algorithm for solving the inverse problem of parametric identification for the aggregated experiment where desorption and diffusion are dynamically interrelated (without the artificial division of studies into the diffusion limited regime (DLR) and the surface limited regime (SLR)).

“…This technique involves heating the sample with different heating rates and respective monitoring the hydrogen degassing rate. By comparing the temperature positions of hydrogen desorption peaks at different heating rates, the binding energy for trapping of hydrogen can be calculated for a specific trap [12,[14][15][16][17][18][19][20]. However, such procedures have their limitations because of dealing with the hydrogen evolution characteristics, but not with the hydrogen behavior directly inside of the test material and its reactions on the hydrogenreleasing process.…”

Hydrogen generally causes lattice distortions and phase transformations when introduced into a metallic crystal lattice. For the investigations reported in this contribution, hydrogen thermal desorption analysis has been carried out to observe the influence of hydrogen desorption on the lattice of super martensitic stainless steel during continuous heating. The lattice expansion parameter and the phase transformations have been monitored during the thermal desorption process, and the influence of hydrogen on such characteristics has been evaluated. It was found that hydrogen has a significant influence on both the lattice parameter and on the thermal expansion. However, hydrogen has no influence on phase transformation during thermal desorption. The hydrogen's desorption behavior in this process was also observed and it turned out that hydrogen desorbs in two stages, i.e., firstly diffusible hydrogen and trapped hydrogen afterward.

“…Computer simulation in the science of materials is being rapidly developed as an interdisciplinary line of investigations. We do no extensive literature survey, but only mention the papers [1][2][3][4][5][6] that deal with the article subject. In these articles, one can find descriptions of experimental methods, corresponding models, data on various materials, and further references.…”

“…But a metal with dissolved hydrogen is considered in [7][8][9][10]. The process of powder metal hydride decomposition under heating is modelled in this article (further development of the subject considered in [1][2][3][4][5][6]). Difficulties considerably increase: one needs to consider the phase change, heat absorption on the moving phase bound, and the particle size reduction effect as the result of the lattice rearrangement.…”

a b s t r a c tIn this paper, we present the boundary-value problem with moving bounds and dynamic boundary conditions that models the kinetics of hydrogen desorption from hydrides of metals. Phase change, desorption processes on the surface, size reduction, and heat absorption on the phase bound are taken into consideration. Computational algorithm based on difference approximations is developed. The results of numerical modeling are presented.
