Crystallization kinetics of melt-spun Fe83B17 metallic glass

The Fe83B17 metallic glass ribbons were prepared by a single roller melt-spinning technique in an atmosphere of helium. X-ray diffraction (XRD), scanning electron microscopy (SEM), and Differential scanning calorimetry (DSC), were used to investigate the structural and thermal transformations of the...

More Information
Summary:The Fe83B17 metallic glass ribbons were prepared by a single roller melt-spinning technique in an atmosphere of helium. X-ray diffraction (XRD), scanning electron microscopy (SEM), and Differential scanning calorimetry (DSC), were used to investigate the structural and thermal transformations of the Fe83B17 metallic glass. The activation energy of crystallization Ec was evaluated using different theoretical models. Applying the modified Johnson-Mehl-Avrami (JMA) equation reasonably suggests that the Fe83B17 crystallization process is carried out by a bulk growth in two dimensions.
