Abstract

Abstract

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.
