Nanostructured disordered iron-aluminium-copper alloy of Fe-30% Al-10% Cu composition was prepared by Self-propagating high-temperature synthesis (SHS) and thermel explosin (TE) techniques of mechanically activated mixture of Fe, Al, Cu powders. The transformations occurring in the material during combustion were studied with the use of X-ray diffraction. Auger spectroscopy and atomic emission spectroscopy (AES) was used to determine the phase composition of the phase formation. Finally, the Magnetic properties were also investigated, for combution processers the magnetic behavior slightly softened becoming a semi hard ferromagnetic.
