We have used Mössbauer spectroscopy and X-ray diffraction to study the influence of different Al/Si ratios on the structural and magnetic properties of the mechanically deformed Fe60Al40−xSix alloys. The results indicate that ternary alloys also present the magnetic transition with disordering observed in binary Fe60Al40 alloys. Besides, Si introduction has two opposite contributions. From a structural point of view, hinders the disordering process, but, from a magnetic point of view promotes the magnetic transition.
• Fe60Al40−xSix alloys were disordered by means of planetary ball milling technique.
• Paramagnetic to ferromagnetic transition is observed with disordering.
• Si addition hinders the disordering process and the increase of the lattice parameter.
• Si addition promotes the paramagnetic to ferromagnetic transition.
