研究了纯Ｃｅ和含１５％Ｃｅ（质量分数，下同）的Ｆｅ－Ｃｅ合金在６００￣８００℃低氧分压下的氧化。纯Ｃｅ氧化后形成ＣｅＯ２的外氧化。而Ｆｅ－１５Ｃｅ则产生快速Ｃｅ的内氧化，且内氧化区的显微组织保持了原始合金的显微组织，在内氧化区的前沿没有观察到Ｃｅ的贫化。
the oxidation of pure Ce and Fe-Ce alloy containing 15% Ce (mass fraction) at low oxygen pressures was studied at 600 -800C . After oxidation pure Ce produced outer Ceq scale, but Fe-15Ce alloy produced rapidly internal oxidation of Ce .?he micmtmctures of the regions of internal oxidation follmd closely the of the original alloys, while no cerium depletion was observed around the internal oxidation front.
