[2M10] In-situ WB-STEM study of annealing process of neutron irradiation induced dislocation loops.
キーワード:RPV, Radiation defect, Electron Microscopy
We developed the weak-beam scanning transmission electron microscopy for effective dislocation analysis in neutron irradiated steels. In this study, double-tilt heating stage was combined with the WB-STEM, then number density, size and Burgers vectors of dislocation loops had been successfully evaluated in post-irradiation annealing process, dynamically in nanometer scale.
