Abstract High-temperature oxidation of E110 (Zr-1%Nb) zirconium alloy in steam at Т = 1100°C to various degrees has been carried out. Based on the studies of morphology and microstructure of the oxide film and metal, as well as on review of previously published results, the mechanism of alloy oxidation has been proposed, which includes oxide thickening close to the oxide/metal interface, growth of the thickened areas and their conversion into nodules, growth of the nodules and crowning of the metal surface (white spots), clustering of nodules under the formed oxide, formation of a double (white on the surface) oxide film and delamination of the oxide upper layer.

更好地理解蒸汽高温氧化下E110锆合金的氧化膜生长机制

摘要 E110（Zr-1%Nb）锆合金在Т=1100℃蒸汽中进行了不同程度的高温氧化。基于对氧化膜和金属的形貌和微观结构的研究，并在回顾之前发表的结果的基础上，提出了合金氧化的机制，包括靠近氧化物/金属界面的氧化物增厚、增厚层的生长。区域及其转化为结节，结节的生长和金属表面的隆起（白点），形成的氧化物下结节的聚集，形成双重（表面白色）氧化膜和氧化物上层的分层。
