Modeling the Thermally Stimulated Evolution of Hydrogen from Ti, Zr, Pd, and Ni

An experimental study is performed of the thermally stimulated evolution of hydrogen in the linear mode of heating (1°C/s). Hydrogen is released from plane-parallel plates of Ti, Zr, Ni, and Pd metals of different thicknesses (0.05–1 mm), preliminarily saturated with hydrogen via electrolysis. Analytical and numerical models of non-stationary processes of the diffusion release of hydrogen from samples are considered with allowance for diffusion and desorption. Programs for numerically modeling processes of thermal gas release are proposed, developed, and perfected.
