Development of heat-treatment process for a P/M superalloy for turbine blades
AbstractPowder metallurgy (P/M) superalloy turbine blades are increasingly being used in jet-aircraft engines. A notable advancement in the manufacture of P/M turbine blades is the development of a powder forge IN-792 nickel-based superalloy: APK-6. Although fatigue strength of the P/M material is times superior as compared to cast blades, its creep strength is poor. The improvement in creep strength is ensured though microstructural control achieved by developing a suitable heat-treatment process.Heat-treatment experiments in the temperature range of 117–1270°C for duration of 20min–22h are conducted. The microstructural characterization involved use of both optical as well as electron microscopes (SEM). Appropriate microstructural features (grain size and γ′ particles size) in the P/M material were achieved through the grain-growth heat-treatment experiments so as to render the material suitable for application in turbine blades of aircraft engines.
