| Popis: | The influence of irradiation conditions on the retention of hydrogen isotopes in structural materials (austenitic steel) under heating is considered. The specimens under study were irradiated either in a reactor or by bombarding them with hydrogen-isotope ions of variable fluence and energy at accelerators. An investigation of irradiated specimens with an EM-300 transition electron microscope was accompanied by studying the kinetics of hydrogen release from samples with a high-vacuum mass spectrometer. Also, the kinetics of hydrogen-isotope release from specimens of structural materials treated with a deuterium plasma was studied. It was found that, under the effect of irradiation, the materials being studied develop radiation defects, which appear to be efficient traps for hydrogen atoms, retaining them up to rather high temperatures (650 K). It is also shown that blisters formed in the materials treated with a hydrogen plasma contain both molecular hydrogen and hydrocarbons—in particular, methane. |
