| 摘 要： | 采用室温离子注入和低压电镜原位观察的方法,研究了注氢对国产ODS铁素体钢微观结构的影响.结果表明:原始未注氢ODS铁素体钢中存在有一定数量的(Fe,Cr)2O3,室温注氢后,(Fe,Cr)2O3无明显改变;但将其加热至450℃,(Fe,Cr)2O3即开始分解;到550℃时,部分(Fe,Cr)2O3消失,残余(Fe,Cr)2O3的成分也发生了改变.与此相反,原始未注氢ODS铁素体钢的微观结构在加热过程中却没有明显改变,(Fe,Cr)2O3并不分解.

| Abstract: | The effect of hydrogen ion implantation on the microstructure of ODS ferritic steel was studied by means of ion implantation at room temperature and in-situ observations in a low voltage electron microscope. The results indicated that a certain amount of (Fe,Cr)2O3 phases existed in the original ODS alloy. They did not change obviously after hydrogen ion implantation at room temperature. During heating the specimen implanted with hydrogen ions, however, the (Fe,Cr)2O3 phase dissolved gradually and the composition of the residual (Fe,Cr)2O3 phase changed too. On the contrary, the microstructure of the specimen which was not implanted with hydrogen ions did not changed obviously during heating, meanwhile, (Fe,Cr)2O3 phase did not dissolve. |
