Meta work - the study of transport processes of hydrogen in zirconium, the study of crystal structure and processes of interaction of hydrogen with alloys based on phase Lavisa that are in different structural states. Metody research - original materials are plastic deformation, arc melting and superfast hardening from the liquid state. Saturation with hydrogen was carried out with materials and electrolyte from the gas phase. The structure studied by methods of X-ray and metallography difraktometriyi. Were used as methods of measuring microhardness, electrical, mass spectrometry. Pry study the kinetics of penetration of hydrogen and deuterium in polycrystalline zirconium showed that for low concentrations of hydrogen on the sample surface, their annealing leads to the formation of solid solution implementation. Thus the activation energy of volume diffusion of hydrogen is UH = 0.52 эВ. In the case of large concentrations of hydrogen on the surface, the bulk of hydrogen diffused with low activation energy Uhydr = 0.16 eV. on grain boundaries, where hydride layer is formed. Dlya alloy Zr-V different set of phases that take them there in cast and superfast hardened states, and after their saturation with hydrogen. Based on the phase state, calculated amount of absorbed hydrogen, which are compared with values that will receive-metric method. Product Description popup.authors І. Неклюдов В. Белан В. Бовда В.
