Abstract
By means of X-ray diffraction (XRD), transmission electron microscopy (TEM), as well as differential scanning calorimetry (DSC) measurements, the sequence of structural evolution by ball milling of polycrystalline and amorphous Fe80B20 alloys was studied. Ball milling of polycrystalline Fe80B20 alloy results in a continuous refinement of the grain size to about 13 nm and a decrease of axial ratio ca for the Fe2B phase. For the amorphous Fe80B20 alloy, with increasing milling time, the amorphous phase crystallizes into α-Fe and a metastable Fe3B phase, followed by the phase transformation from the resulting metastable Fe3B phase into α-Fe and the stable Fe2B phase, which are also nanocrystalline. The decreased axial ratio ca for Fe2B phase indicates that chemical disordering is introduced during the mechanical deformation.
