Practical Guide to High-Temperature Alloys (10056)
By Peter Elliott, reprinted from Materials Performance, Aug 1990. High-temperature materials are used for many critical components in a number of industries including power generation, chemical processing, and gas turbine. With ever-continuing demands for increased throughput and efficiency, there has been a trend towards higher service temperatures and pressures. This has resulted in continued corrosion problems, countered by continued improvements in material compositions, coating procedures and improved fabrication, notably casting, forging and welding. All these aspects are discussed.
