Helium embrittlement poses a major challenge for the application of ferritic/martensitic steels in future nuclear devices. The strategy for an effective suppression of helium embrittlement is to reduce the mean free diffusion path of helium by way of introducing nanoparticles into the steel. The study is aimed at clarifying the role of oxide nanoparticles on the formation of helium bubbles and related hardening for the case of He-ion irradiations performed in the He-ion microscope (HIM).
