Scales formed on eleven heat-resisting alloys in common use at temperatures between 850° an 1350°C were investigated by X-ray diffraction method. The following results were obtained. (1) On Fe-base alloys the scales consisted of (Fe, Cr)2O3 and spinel-phase oxide. On Co-base alloy Cr2O3, spinel-phase oxide and other oxides were formed, on Ni-base alloys Cr2O3, spinel phase oxide, NiO (or (Ni,Co)O) and other oxides. (2) On Ni-base, Co-base and Fe-Ni-Co-Cr alloys containing molybdenum, (Ni, Co)OMoO3 was formed and fused at the temperature of oxidation resistance limit of each alloy. (3) On such alloys containing tungsten as S 816 and LCN 155, (Co,Ni)OWO3 was formed. (4) On Ni-base alloys containing titanium, TiO2 and NiOTiO2 (or (Ni,Co)OTiO2) were formed. (5) On such alloys containing niobium as Inconel X and S 816, CrNbO4 was formed.
