The amorphous-crystalline transitions in Fe84B16 alloy received by spinning melt and high-energy ball milling have been studied. Using time-resolved X-ray diffraction method, it has been shown that the kinetics of transition in crystalline state depends on the method of metastable alloy production. In amorphous alloy Fe84B16, received by spinning melt, the crystallization process goes on for a short period of time not exceeding 1 s and is accompanied by formation of eutectic α-Fe-Fe3B. At a temperature of more than 600 ℃ metastable phase Fe3B transition into Fe2B and α-Fe. In amorphous alloy Fe84B16, received by high-energy ball milling, structural changes occur within 4-8 s and transition in state with perfect crystalline structure associated with growth of nanoscale crystallites.
