Application and Development of High-temperature Alloys for Gas Turbines

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.
