Abstract:
The effects of hydrogen/electron dual-beam irradiation on the stability of oxide particles of a new 12Cr-ODS ferrite steel made by chemical socking method was studied in this paper.The observation of the microstructure of oxide particles under different irradiation doses show that,before irradiation and after an irradiation dose to 15dpa,the size of 10-20nm oxide particles have little change,the small number density voids have no effect on the stability of the oxide particles;as temperatures increased to 823 K,the phase inter-face of the bigger size dispersed oxide become irregular,while the size of the oxide particles remain stable.The results show that,the size of the dispersed oxide is stable,no solubility process was observed.
