英文摘要	Transmutation helium may causes serious embrittlement which is considered to be due to helium from clustering as a bubble in materials. suppression of transmutation helium can be achieved by introducing trapping sites such as dislocations and impurities in materials. here, effects of intentionally-induced dislocations and hydrogen on helium migrate and release behaviors were investigated using thermal desorption spectrometry (tds) technique applied to well-annealed and cold-worked fe9cr alloys irradiated by energetic helium/hydrogen ions. synchronous desorption of helium and hydrogen was observed, and the microstructure states during helium release at different temperatures were analyzed. high thermally stable hend type complexes formed in cold-worked specimens, resulting in the retardation of helium migration and release. the existence of hydrogen will strongly affect the thermal helium desorption which could be reflected in the tds spectrum. it was confirmed that hydrogen retained in the specimens can result in obvious delay of helium desorption.
