| Popis: | A recent experiment for hydrogen retention in F82H steel by thermal desorption spectroscopy after deuterium-ion irradiation shows the primary precipitates of metal carbide such as M23C6 and MX might play a role of remarkable trap site for hydrogen isotopes. However, the trapping and diffusion behaviour of hydrogen isotopes is not understood well. Since it is well known that vacancies in crystals are major trapping sites for hydrogen, the purpose of this study was to theoretically understand fundamental feature of the interaction between vacancies and hydrogen in carbides by density functional theory calculations. 20th International Conference of Fusion Reactor Materials |
