摘要：
A study was conducted to observe the oxidation of NiAl+3.5at.%Fe alloy in beta-NiAl phase field at air temperatures of 1000, 1200 and 1400 degrees C, and these results were compared with those of pure NiAl alloys. The primary effects of the Fe-addition in NiAl were found to be: 1) decrease in oxidation resistance and adherence of scales during both isothermal and cyclic oxidation tests, 2) enhancement of phase transformation rate from theta- to alpha-Al2O3, 3) more rapid formation of characteristically ridged alpha-Al2O3 scales during initial oxidation stages, and 4) partial sealing of voids formed at the scale-substrate interface and dissolution of Fe inside the alumina scale by the outward diffusion of Fe from the substrate alloy.
