摘要	An ultrafine-grained (UFG) Ni(3)Al was fabricated by annealing an electrodeposited Ni-Al composite in vacuum at 600 degrees C for 2 h. The UFG Ni(3)Al, compared to a compositional-similar but coarse-grained (CG) alloy prepared by arc-melting, exhibited a greatly increased cyclic oxidation resistance at 900 degrees C. Microstructural investigation showed that the CG alloy grew a scale with a high susceptibility to buckling and cracking because of the formation of large voids at the scale/metal interface, but that the UFG alloy grew an adherent scale, because its typical structure prevented the formation of the interface void during oxidation.
