Description

Irradiation damage behavior was investigated by hydrogen ion-electron ion (H+ + e-) dual-beam irradiation. The morphology change was observed in-site, and the effect of (H+ + e-) dual-beam irradiation on the stability of oxide particle (Y2O3) in a new 12Cr-ODS ferrite steel, which was produced by using ethylene diamine tetraacetic acid (EDTA) complex method, was studied in this work. The results show that after electron ion irradiation with a dose of 15 dpa followed by an (H+ + e-) dual-beam irradiation dose of 15 dpa, the size of Y2O3 particles decreased or dissolved in this particular condition, and the radiation-induced point defects and the chemical reaction around the interface are the main reasons for the instability of the oxides.
