AB This work describes properties of newly developed Fe-Al-Si alloy for high-temperature applications. This alloy is a material composed of FeAl, FeSi a Fe3Al2Si3 intermetallic compounds, which was prepared by powder metallurgy using mechanical alloying and spark plasma sintering. The oxidation resistance at the temperatures of 800 and 1000 °C was described, as well as the mechanical properties up to 700 °C. During oxidation, the alloy covers by aluminium oxide layer, which protects it against further oxidation. Concerning the mechanical properties, the yield strength and ultimate compressive strength increase in the temperature interval of 400 - 500 °C.
