| Abstract Scope |
The demand for metal alloys that can perform at extreme temperatures above 1100°C while remaining manufacturable has sparked renewed interest in printable oxide dispersion strengthened (ODS) alloys. Recently, NASA developed an ODS alloy designed for additive manufacturing, known as GRX-810, which has demonstrated exceptional tensile and creep performance at temperatures of 1093°C and higher. In the present study, tensile tests of GRX-810 were conducted up to 1316°C and creep tests were performed in both the horizontal and vertical orientations, relative to the build direction. Thermal cycling was executed at 1100°C, 1200°C, and 1300°C in air. The oxidation behavior of GRX-810 is compared to that of alumina forming single crystal Ni-base superalloys and chromia-forming wrought alloys such as superalloys 718 and 625. High resolution atomic-scale characterization and atomistic modeling are employed to explain the exceptional high temperature properties observed in GRX-810, particularly in relation to the oxides produced during the additive manufacturing process. |
