Abstract

The effect of reactive elements on the segregation behavior of alumina-nitride alloy grain boundaries was investigated. β-NiAl doped with 0.23 wt % Zr was oxidized in 1 atm O₂ at 1500 °C for 50 h. The α-Al₂O₃ scales formed by the oxidation process were subsequently annealed without any oxygen potential gradient. Scanning transmission electron microscopy was then used to analyze the microstructure and grain boundary segregation levels between the alumina-alloy interface. The results are presented in this paper.
