| 内容記述 | One of the characteristics of a fusion reactor is that a large amount of gas atoms such as hydrogen and helium are produced by a transmutation reaction. The hydrogen isotopes interact with irradiation-induced defects and are retained in the material. This leads to the change in the mechanical properties of the material (hydrogen embrittlement etc.). Elastic strain is high near the edge dislocation cores or coherent interfaces. The strain has an effect on the hydrogen solution, and the binding energy of hydrogen to defects. Therefore, the investigation of interaction between hydrogen and defects under elastic strain is important. The purpose of this study is to obtain the binding energy of hydrogen atoms to vacancies and vacancy-carbon complexes under elastic strain in α-Fe, and to estimate the hydrogen retention in the strained Fe. | |||||
