The Effects of Small Deformation on Creep and Stress Rupture Behavior of ODS Superalloys.

Abstract

This Air Force sponsored research program studied the effects of predeformation including periodic load cycling on the creep and stress rupture of oxide dispersion strengthened (ODS) high temperature alloys. The alloys most studied in this program are Inconel MA 754, a Ni-Cr alloy strengthened by oxide dispersoids, and MA 6000, strengthened by both the oxide dispersoids and gamma prime precipitates. At temperatures above 1093 degrees C, these alloys have better creep resistance than any current high temperature alloy. The MA 754 alloy is now used as stator components in the hot sections of jet engines and MA 6000 is the only candidates turbine blade ODS alloy. (Author)
