The high-temperature oxidation behaviour of Fe28Al3Cr0.02Ce and Fe30Al4Cr2.7TiB(2) (in at.%) has been investigated at 900 and 1100 degrees C for up to 2000 h. in air. The corrosion resistance was determined by measurement of weight gains.
After oxidation the surface layer and the scales were analysed by light optical microscopy (LOM), electron probe microanalysis (EDX) and X-ray diffraction (XRD). Parabolic rate constants k(p) was compared with other Fe(3)Al alloys.
