【摘要】 氧化物弥散强化（ＯＤＳ）铁素体合金具有强度高肿胀低等优点，是核反应堆中包壳及其它结构的极有竞争力的候选材料。本文介绍了在研究化学浸润法（ＣＳ）生产的Ｆｅ１２５Ｃｒ２５Ｗ０１Ｔｉ０４Ｙ２Ｏ３新型ＯＤＳ铁素体合金方面所进行的工作及取得的进展。化学浸润法可以实现氧化物弥散强化，获得优良的力学及抗肿胀性能，形变后再结晶退火能够得到晶粒尺寸适中的组织，有利于材料穿管及冷拔等后续加工。更多还原

【Abstract】 Because of their high strengthes and low swelling properties,oxide dispersion strengthened (ODS) ferritic steels are competitive structural materials in reactors. This paper introduced our studies of a new type of ODS ferritic steel .The alloy with a composition of Fe12 5Cr2 5W0 1Ti0 4Y 2O 3 was manufactured through Chemical Socking (CS),which can also disperse oxides.The alloy has good mechanical and swelling resistance properties.Medium grain size can be obtained through recrystallization,which was thought to be benificial to the piercing and cold drawing of tubes.更多还原
