合金的高温抗氧化性是各种工业应用中部件的关键设计标准，例如先进的燃气轮机、工业加热、汽车、垃圾焚烧、发电和能量转换、化学和石化加工以及金属和矿物加工。说明了正确评估高温合金长期氧化行为的重要性。随着应用转向更高的温度，需要新的合金。本文介绍了三种新开发的合金，即形成氧化铝的Ni-Fe-Cr-Al合金、γ′强化的Ni-Cr-Co-Mo-（Al+Ti）合金和氮化物强化的Co-Cr-Fe-Ni-（Ti+Nb）合金的氧化性能。
The high-temperature oxidation resistance of an alloy is a key design criterion for components in a variety of industrial applications, such as advanced gas turbines, industrial heating, automotive, waste incineration, power generation and energy conversion, chemical and petrochemical processing, and metals and minerals processing. The importance of correctly assessing the long-term oxidation behavior of high-temperature alloys is illustrated. As applications move to higher temperatures, new alloys are needed. In this paper, the oxidation performance of three newly developed alloys, an alumina-forming Ni-Fe-Cr-Al alloy, a γ′-strengthened Ni-Cr-Co-Mo-(Al+Ti) alloy, and a nitride-strengthened Co-Cr-Fe-Ni-(Ti+Nb) alloy is presented.
