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(Y
2O
3) 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 Y
2O
3 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.
