| 内容記述 | In fusion reactor materials, a large amount of gas atoms are formed by the nuclear reaction. The hydrogen isotopes interact with the irradiation-induced defects, and remain in the materials. Retention of hydrogen isotopes leads to a decrease in mechanical properties of materials, e.g. hydrogen embrittlement. Therefore, to study the interaction between hydrogen and defects is especially important. Positron annihilation spectroscopy (PAS) is a non-destructive technique for detecting vacancy type defects. In this study, the possibility of quantitative evaluation of hydrogen atoms trapped at vacancy-type defects using the PAS was investigated in the tungsten hydrogen-charged under different conditions. | |||||
