THE CRYSTALLIZATION KINETICS OF AMORPHOUS-ALLOYS

The crystallization kinetics of Fe-based amorphous alloys was investig ated by differential thermal analysis (DTA) and differential scanning calorimetry (DSC). Rather high values of activation energies were expl ained as a result of simultaneously correlated displacements of groups of atoms during the course of crystallization and allowed the correla tion of amorphous alloys regarding their different composition. Connec tions between the temperatures, activation energies and thermodynamic driving forces were considered. Special attention was paid to the form ation of nanocrystalline structures (Finemet).
