Abstract

H-Series austenitic steels are used extensively in several industries for a range of high-temperature applications. Good creep properties of these steels are vital for many such applications. The microstructure of these alloys consists of an austenitic matrix along with dispersions of carbides. This paper highlights the results of a study on the effect of precipitation of carbides on the creep properties of two HP-type alloys with different Nb-contents. Thermodynamic modeling, microstructural characterization, and mechanical property measurements were used to study the relationship between the precipitation of carbides and the creep properties of these two alloys. It was found that precipitation of M 23C 6 carbides played an important role in determining the creep properties of these alloys.
