The nanocrystalline state of the formally amorphous alloy Fe_{73.5}Cu_{1}Nb_{3}Si_{15.5}B_{7} is achieved by a heat treatment at temperatures between 500°C and 600°C. The XANES and EXAFS methods were applied for investigation of local structure and chemical bonding around Fe atoms in amorphous and nanocrystalline alloys. The Fe K absorption spectra were measured in the transmission mode at room temperature for Fe_{73.5}Cu_{1}Nb_{3}Si_{15.5}B_{7} amorphous and nanocrystalline alloys and compared with the spectra for Fe metallic foil and Fe_{3}Si polycrystalline samples.
