Abstract:

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.
