Nickel and cobalt-base superalloys are widely used in many military and commercial aircraft turbine engines for vanes and other high temperature structural components, owing to their good mechanical properties stress and excellent hot corrosion resistance after prolonged exposure. Cobalt-base alloys, unlike nickel base superalloys, are not strengthened by a coherant, ordered precipitate. The presence of carbide phase has long been recognized as an important strengthening mechanism in cobalt-base superalloys. In this paper, the microstructural changes in nickel base and cobal base superalloys arrisen after thermomechanical treatments are observed by light and scanning electron microscope and analysed by energo-dispersive sprectrometry
