The nature of the scales formed on Cr-Cr2Nb alloys was studied for exposures to air at 900 and 950 °C. The kinetics, scale composition, and spallation tendencies of Cr -6 and -12 at. % Nb alloys were characterized. Multilayer scales with a pure chromia outer layer were formed, and the alloy with the higher niobium content performed significantly better in terms of overall weight gain and resistance to spallation. This behavior was ascribed to an increased volume fraction of the Cr2Nb-Cr eutectic mixture at the expense of the Cr-rich phase.
