抄録

The oxidation or nitridation behavior of pure chromium and chromium alloys containing 10 mass%Ni or 10 mass%Fe in atmospheric heating was investigated in the temperature range of 1073 to 1373 K. The formation behavior of the outer oxide phase of Cr₂O₃ and its growth kinetics in both chromium alloys was very similar to that of pure chromium. The nitride layer with the Cr₂N phase was formed beneath the oxide phase at temperatures above 1273 K in pure chromium. Marked internal nitridation with the formation of the Cr₂N phase was observed in the Cr-10 mass%Fe alloy, while the formation of Cr₂N was negligible in the Cr-10 mass%Ni alloy. Neither Ni nor Fe were detected inside the Cr₂O₃ phase, and was enriched in the subsurface layer between the oxide layer and the base alloy in a respective alloy. The Ni-enriched layer in Cr-10 mass%Ni alloy had a relatively narrow width, but a very high concentration of Ni compared with the Fe-enriched layer formed in the Cr-10 mass%Fe alloy.
