Fe-based nanocrystalline alloys were prepared by the melt-spinning technique and characterized by X-ray diffraction, magnetostatic and Mössbauer effect methods. The Mössbauer spectroscopy allows to study the local environment of the Fe atoms in the investigated Fe80-xNixB20 (x=8, 16, 24, 28) compounds and showing the changes in the structure due to the changing of Ni addition. Combination of X-ray diffraction and Mössbauer spectroscopy results confirm formation of different number of phase complex, including the α-FeNi, γ-FeNi, FeB, Fe2B, Fe3B in the investigated materials together with increase of Ni content.
