| Примечания: | Title screen Hydrogen sorption-desorption processes by zirconium alloy Zr-1Nb was investigated in this article. Sievert apparatus was used for investigation of hydrogen interaction with material. It was shown that hydrogenation at gas atmosphere at 350, 450 and 550 °С temperatures leads to the [delta]-hydride formation in all material volume. Hydrogen sorption rates were calculated on the linear parts of sorption curves and equal to 0.5·10{-4} wt%/s at 350 °С, 9.5·10{-4} wt%/s at 450 °С and 23.1·10{-4} wt%/s at 550 °С. Short-wave diffraction of synchrotron radiation was used for investigation of hydrides dissociation during heating. Hydrides dissociation formed after hydrogenation at gas atmosphere occurs at temperature 522-540 °С. Further temperature increasing leads to [beta]-phase appearance which indicates α to beta phase transition at zirconium. Режим доступа: по договору с организацией-держателем ресурса |
