SUPERALLOYS APPLICATIONS IN AEROSPACE • The range of applications for which superalloys are used has expanded to many other areas and now includes aircraft and land-based gas turbines, rocket engines, chemical, and petroleum plants. • They are particularly well suited for these demanding applications because of their ability to retain most of their strength even after long exposure times above 650°C (1,200°F). Their versatility stems from the fact that they combine this high strength with good low-temperature ductility and excellent surface stability.
