| Abstract Scope |
The complex geometries required of high temperature aerospace components can be addressed using metal additive manufacturing (AM). A novel AM CrNiCo-based alloy containing Ti, Al, Nb, W, Re, and Y, known as GRX-810, was determined to have excellent high temperature creep properties at 1093°C. However, its oxidation response hasn't been studied and the synergistic effects of the minor alloying elements on the oxide scale morphology and kinetics of oxide growth are not well understood. Consequently, this study aims to understand the individual role of alloying elements on the oxidation of CrNiCo alloys. Characterization of the oxide morphology and elemental distributions in the oxide scale and underlying alloy provided unique insight into the nanoscale mechanisms behind the alloys' oxidation response. |
