The dispersion of CeO2nanoparticles resulted in a decrease of the oxidation rate of an ultrafine-grained Ni2Al3at 1000°C. The reason is explained as follows. During oxidation many Ce ions are released from the CeO2nanoparticles that are enveloped by the inward growing α-Al2O3from the scale/metal interface due to an increased solubility. The Ce ions transport outward along grain boundaries of the scale, retarding the diffusion of Al ions for the thickening of the outer θ-Al2O3. This explanation is consistent with an observation that many CeO2nano-precipitates appeared mainly in the near-surface zone of the formed alumina scale.
