研究了用化学浸润法（CS）进行氧化物弥散强化（ODS）的铁素体合金形变后在退火过程中的组织变化．结果表明：合金的再结晶温度在750～780℃之间；形变量高的合金退火后能获得细小均匀的晶粒；弥散相能有效钉扎初次再结晶完成后晶粒尺寸在临界尺寸Dlim以下的晶界；弥散强化相Y2Ti2O3在形变和退火过程中是稳定的.
The microstructures of the ferritic alloys after chemical vapor deposition (CS) deformation during the annealing process were studied. The results show that the recrystallization temperature of the alloy is between 750 and 780 ℃. The alloy with high deformation can obtain fine and uniform grains after annealing. The effective size of the pinning after dispersion is effective. The grain size after the primary recrystallization is below the critical dimension Dlim The grain boundary phase of Y2Ti2O3 is stable during deformation and annealing.
