Nickel based superalloys are used within the industrial gas turbine (IGT) engine manufacturingindustry, specifically to meet the needs of the hot gas path components. These are exposed to themost severe operating conditions where high temperature creep, tensile strength, ductility andoxidation resistance are required to withstand the loadings imposed. A range of nickel basedsuperalloys, from dilute, solid solution strengthened alloys to the highly alloyed precipitation hardenedmaterials, have been developed to meet the needs for high temperature structural performance andenvironmental resistance.
