**4. Conclusions**

In the present work, the oxidation behavior of the Al71Co29 and Al76Co24 alloys (concentration in at.%) was studied at 773–1173 K in air. The alloys were prepared by rapid solidification of Al and Co lumps in argon. The alloys were studied in as-solidified state. The following conclusions can be drawn:
