Iron disilicide synthesis by mechanical alloying was performed. -FeSi, α-Fe_1−xSi₂, amorphous FeSi₂ were formed with relative intensities depending on the milling period. β-FeSi₂ phase was formed after annealing the gridded powder at the temperature where this phase is stable. Mössbauer spectroscopy and X-ray diffraction methods were applied to determine the different phases formed. The morphology of the resulting particles was observed by high resolution scanning electron microscopy. The effect of the milling on bulk iron–silicide samples was and studied chemical effects of the ball milling on Fe–Si₂ systems have been studied.
