The microstructural and high-temperature mechanical properties of Fe-26Al-xNb (x = 3 and 5 at. pct) are compared. The alloys were investigated as cast and after hot rolling at 1473 K (1200 A degrees C). Scanning electron microscopes equipped with EDS and EBSD were used for the microstructure and phase identification. The addition of 3 at. pct of Nb into the Fe3Al matrix leads to the formation of C14 lambda-Laves phase (Fe,Al)(2)Nb (LP) particles spread in the Fe3Al matrix, while an eutectic with thin lamellae of LP C14 lambda-Laves phase (Fe,Al)(2)Nb and matrix is also formed in the iron aluminide with 5 at. pct of Nb. The presence of incoherent precipitates is connected with the enhancement of the high-temperature strength and creep resistance.
