| 摘 要： | 一类以在材料表面形成Al2O3膜的奥氏体不锈钢（AFA）的开发正如火如荼地在全球展开。这类合金与传统的、在其表面形成Cr2O3膜的不锈钢相比，在不牺牲其成本、蠕变抗力和可焊性等其它性能的同时具有更高的使用温度和更好的耐环境侵蚀能力。作者简要介绍了该合金的开发方法和其抗氧化和蠕变抗力方面的数据。

| Abstract: | A family of alumina (Al2O3)-forming austenitic (AFA) stainless steels is under development. These alloys offer the potential for significantly higher operating temperature and environmental durability than conventional chromia (Cr2O3)-forming stainless steels, without sacrificing other critical characteristics such as cost, creep resistance, and weldability. An overview of the alloy development approach and details of the oxidation and creep resistance properties achieved to date are presented. |
