Continuous exploration of high-temperature structural materials is being driven by the needs of gas-turbine engines capable of withstanding the high-temperature environment. Relatively low melting points of currently applied superalloys restrain the further improvement of service temperatures. With higher melting temperatures above 2000 °C, Mo-Si-B alloys are regarded as a new generation of ultrahigh-temperature structural materials. However, oxidation is a concern for the industrial application of Mo-Si-B alloys. Therefore, an in-depth understanding of the oxidation mechanisms may contribute to solving this issue, whereas relevant reviews about their recent advances are lacking. In the current work, a comprehensively systematic review about the oxidation behaviors of Mo-Si-B alloys is described for this purpose.

能够承受高温环境的燃气涡轮发动机的需求正在推动对高温结构材料的不断探索。当前使用的高温合金的相对较低的熔点限制了使用温度的进一步提高。Mo-Si-B合金具有高于2000°C的较高熔化温度，被视为新一代超高温结构材料。然而，氧化是Mo-Si-B合金的工业应用中的关注点。因此，对氧化机理的深入理解可能有助于解决这个问题，而对它们的最新进展缺乏相关的评论。在当前的工作中，为此目的对Mo-Si-B合金的氧化行为进行了全面的系统综述。
