摘　　要：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.Recrystalization of the dispersion strengthened fetrihc steels, which wasmanufacted through chemical socking, was systemahcally studied. It was found that the recrystaization temperatures varied from 750 to 780℃, fine grains could be obtained by annealing after high-level deformation, grain boundaries of the grains with size smaller than limited value could be effectively Pinned by dispersoids, and Y2 Ti2 O7 was stable during deformation and annealing.
