Abstract


Ni-base superalloy C263 has been oxidized from 700 °C to 1100 °C in artificial dry air. A continuous Cr rich (Cr, Ti)2O3 layer is formed during oxidation, while the oxidation kinetics deviated from the parabolic kinetics. The oxidation microstructures were different in as-machined and polished samples. Recrystallization below the oxide layer occurred in as-machined samples together with severe internal degradation (internal oxidation and  nitridation). Grain boundaries provide paths for fast diffusion of O and N into the substrate and outward diffusion of Ti and Cr. Surface deformation and recrystallization exhibit detrimental effects on the oxidation behavior of C263.
