Abstract


Several experimental superalloy compositions based on the alloy IN792 were investigated. Creep rupture properties were measured and microstructures in the as-heat-treated condition and after creep rupture testing were evaluated. Two types of topologically closed packed (TCP) phases have been observed. Type 1 occurs in alloys with increased additions of the γ′-formers Al and Ta and shows detrimental effects on creep rupture life. Type 2 precipitates in Re-containing alloys are much smaller in size and volume fraction than type 1 and are found not to influence the creep rupture properties. The different effect of type 1 and 2 TCP phases can be rationalized in terms of the amount of precipitate and the resulting matrix depletion of solid solution strengtheners.
