Изучение и моделирование нестационарных процессов диффузии водорода в титане

Abstract

The behavior of hydrogen in metals is becoming an increasingly multidisciplinary interdisciplinary problem at the intersection of physics and solid state chemistry. The expansion of the range of problems studied is due to the expanding use of metal-hydrogen systems: the accumulation of hydrogen in hydrides and its use as environmentally friendly fuels, the materials science aspects of the use of hydrogen in nuclear, thermonuclear and hydrogen energy, for purifying hydrogen and separating its isotopes. Since the interaction of hydrogen with a metal, including the diffusion of hydrogen, determines the physical and physicochemical properties of materials, it is important to study the kinetic processes in metal-hydrogen systems, including the solution of diffusion problems. In this case, we carried out an experimental study and simulation of the processes of hydrogen diffusion to vacuum from previously flattened hydrogen metal plates of different thicknesses under thermal heating, and compared the results of numerical and analytical modeling with experiment.
