摘 要
对真空感应熔炼的Inconel718合金进行了电子束精炼，在900，1 000 ℃空气中对电子束精炼前后的合金进行了恒温氧化试验，对比分析了其高温氧化行为。结果表明：电子束精炼后，合金在900 ℃氧化120 h后的平均氧化速率为0.366 20 g·m-2·h-1，低于精炼前的，氧化激活能为280.90 kJ·mol-1，高于精炼前的；900 ℃和1 000 ℃氧化120 h后，电子束精炼合金氧化膜的外层由Cr2O3和TiO2组成，中间层主要含有Cr2O3以及少量的TiO2和NiCr2O4尖晶石，内层主要含有Al2O3；电子束精炼合金中微量杂质元素的含量较低且均匀分布，晶粒尺寸较大，合金的抗氧化性能较好。

Abstract
Vacuum induction melted Inconel718 alloy was refined by electron beam smelting. The high temperature oxidation behaviour of the alloy before and after electron beam refining was studied and compared by isothermal oxidation tests in the air at 900, 1 000℃. The results show that the average oxidation rate of the electron beam refined alloy oxidized at 900℃ for 120 h was 0.366 20 g·m-2·h-1, smaller than that before refining; the oxidative activation energy was 280.90 kJ·mol-1, higher than that before refining. The outer layer of the oxide film of the electron beam refined alloy oxidized at 900℃ and 1 000℃ for 120 h was composed of Cr2O3 and TiO2, the middle layer consisted of Cr2O3 and a small amount of TiO2 and spinel NiCr2O4, and the inner layer was mainly composed of Al2O3. The content of trace impurity elements distributed evenly in the electron beam refined alloy was relatively small, grain size was larger,and the alloy had a better antioxidant property.
