The local atomic arrangement for Fe-B amorphous alloys in both as-prepared and mechanically deformed states was investigated by a laboratory EXAFS spectrometer. It was found that the nearest neigh-bour distance changed drastically at 16 to 18 at% of B atom concentration and that the mechanical deformation (cold rolling and tension yielded the non-uniform displacement of Fe atoms in Fe-B amorphous alloys, keeping the Fe-B correlation unchanged
