Abstract	Aluminium based rapidly quenched alloys of nominal composition Al90Fe7Nb3 and Al94Fe2V4 were studied by Mössbauer spectroscopy. Samples annealed up to 573 K showed amorphous structure represented by quadrupole doublet. From corrected spectra areas the values of f-factor were calculated. In the case of AlFeNb samples f-factor was estimated as f = 0.26 and for AlFeV f = 0.31. The corresponding Debye temperatures were also calculated. Higher temperature annealing at 773 and 873 K induced deformation of nano- and microcrystalline state. Mössbauer spectra of samples of both compositions (with vanadium as well as with niobium) annealed at 773 K showed superposition of crystalline phases with dominant role of Al3Fe alloy. During annealing at 873 K, phases with large grains and small amount of FeAl metastable phase were developed (Das et al. Mat. Sci. Eng., A304–A306, 159, 2001; Illeková et al. Mat. Sci. Eng., A375–A377, 946, 2004).
