An ordering process of atom cluster occurs prior to the crystallization. Above experimental sequence of crystallization of (Fe0.99Mo0.01)(78)Si9B13 metallic glass could be understood in terms of the Gaskell model, There is a high strain (0.33%) in the alpha-Fe(Si, Mo) (bcc) grain with 37 nm, and the strain relaxation leads to the distortion in the lattice parameter of nanocrystallite.
