Stress-controlled fatigue tests were performed for He-pre-injected 316 stainless steels under in situ 17 MeV proton irradiation at 573 K. The pre-injection of He for fatigue specimens was conducted with 20 MeV α particles to a level of 100 appm at 5

In situ stress-controlled fatigue tests were performed for F82H steels under 17 MeV proton irradiation with an energy degrader at 60 °C. The energy degrader enhanced the hydrogen implantation rate from 2.6 × 10 −6 to 1.3 × 10 −3 appm/s at a do

Although fusion blankets are exposed to severe irradiation, its rear side would stay at rather a modest condition. In this research, the irradiation-induced deformation of F82H IEA-heat steel at 300 °C was examined. A torsion creep apparatus with a

In order to contribute to the development of first wall/blanket structural materials in nuclear fusion reactors, we have assessed the influence of nuclear-transmutational helium, which is widely known to often induce grain boundary embrittlement at h

Stress-controlled fatigue tests were performed for 5% and 15% cold-worked 304 stainless steels under in-situ irradiation with 17 MeV protons at 300°C. Increase of fatigue life with prolonged crack propagation length under in-situ irradiation was det

Austenitic stainless steels will be used in ITER as a major structural material. Although, initially supplied in annealed condition, cold-working is inevitable during construction or operation. Martensite would be introduced by cold-work in the case
