利用氢离子和电子双束(H~+/e~-)对用化学浸润法制备的新型12cr-ODS铁素体钢进行辐照,研究了辐照对12Cr-ODS钢氧化物稳定性的影响.对不同辐照剂量下原位观察辐照区内氧化物形貌的变化过程发现:辐照前和15 dpa辐照后,约10～20nm氧化物的尺寸并没有明显变化,而氧化物周围出现微小高密度空洞并没有影响氧化物的稳定性;当辐照温度升高至823 K时,大尺寸的氧化物Y_2O_3与基体的相界面变得不规则,但氧化物颗粒尺寸并不发生明显变化.实验结果表明:弥散强化相Y_2O_3尺寸稳定,无明显溶解现象.

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 823K, the phase interface 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.
