用化学和机械合金化两种方法将Ｙ２Ｏ３复合到铁素体不锈钢粉中，经热等静压后制成氧化物弥散增强（ＯＤＳ）铁紊体不锈钢，研究了其中的氧化物相的结构和成分与这两种复合方法的关系。结果表明，采用化学法的钢中复合相主要存在Ｙ２Ｔｉ２Ｏ７相，而机械法钢中复合相主要存在Ｙ２Ｏ３相；两种复合工艺制备的ＯＤＳ钢中氧化物的钛含量有明显差异，而钇含量则与复合工艺关系不大。 Y2O3 was compounded into ferritic stainless steel powder by both chemical and mechanical alloying methods. After hot isostatic pressing, an oxide dispersion enhanced (ODS) ferritic stainless steel was prepared and the structure of the oxide phase and Composition and the relationship between the two composite methods. The results show that there are mainly Y2Ti2O7 phases in the composite phase of the steel by chemical method, and Y2O3 phase mainly in the composite phase of the mechanical method steel. The titanium content in the ODS steel prepared by the two composite processes is obviously different, while the yttrium content Little relationship with the composite process.
