Data for: Helium-ion microscopy, helium-ion irradiation and nanoindentation of Eurofer 97 and ODS Eurofer

A set of He-ion irradiations was aimed at visualizing irradiation-induced changes directly in the HIM using the video mode. Video files for Eurofer 97 and ODS Eurofer of the in-situ irradiation experiments in the HIM (Ion energy 30 keV, maximum fluence 2E18 He ions/cm2, linear time scale) are provided. We have observed that the onset of blistering takes place slightly above a fluence of 5E17 He ions/cm2 for Eurofer 97 and slightly below this value for ODS Eurofer.

本数据集通过一系列氦离子辐照实验，旨在借助视频模式直接观测氦离子显微镜（Helium Ion Microscope，HIM）内由辐照诱导的微观结构变化。本数据集提供了Eurofer 97与氧化物弥散强化（Oxide Dispersion Strengthened，ODS）Eurofer在氦离子显微镜内开展的原位辐照实验的视频文件，实验参数如下：离子能量30 keV，最大注量2×10^18 氦离子/平方厘米，采用线性时间尺度。经观测发现，Eurofer 97的起泡现象起始注量略高于5×10^17 氦离子/平方厘米，而ODS Eurofer的起泡起始注量略低于该数值。更多实验细节请参阅正文。
