Abstract
INCONEL® alloy 617 is a solid solution, nickel-chromium-cobalt-molybdenum alloy with an exceptional combination of high-temperature strength, oxidation and carburization resistance and thermal stability. In this paper, the performance of alloy 617 in actual and simulated gas turbine environments will be presented. In addition some mechanical property data will be included to show the stability of the alloy after exposure to high temperatures for an extended period of time. For comparison the data obtained on such alloys as INCO® alloy HX, Haynes alloys HS188®, 214® and 230® are also reported. (INCONEL and INCO are trademarks of the Inco family of companies.
