高温材料在燃气轮机中的应用和发展

Application and Development of High-temperature Alloys for Gas Turbines

高温合金材料是燃气轮机材料中极其重要的组成部分。在燃气轮机燃烧室、导向叶片、涡轮动叶片以及涡轮盘等部位上都有着极其广泛的应用。本文就当前燃气轮机所采用高温合金的主要特点及新技术的应用情况进行了分析和说明,并对目前世界主要国家的研制水平和发展趋势进行了深入的介绍。

High-temperature alloy materials represent a very important integral part of the gas turbine materials. They are very widely used to make major components and parts of a gas turbine, such as combustors, guide vanes, rotor blades and turbine discs, etc. The authors have analyzed and explained the main features and new technology of the high-temperature alloys currently used in gas turbines. Moreover, an in-depth and detailed account is given of the research and development status and tendency of these alloys in some developed countries worldwide.
