Crystallization of α-Fe phase in amorphous Fe81B13Si4C2 alloy

The crystallization kinetics of α-Fe from the amorphous Fe81B13Si4C2 alloy was investigated by DSC and XRD methods. The kinetic parameters (ln A, Ea) of the investigated process were determined using Kissinger's as well as isoconversional (model-free) method. Based on the results of DSC and XRD analysis and calculated crystallization parameters (n = 4; m = 3) it was concluded that primary crystallization of α-Fe phase in amorphous matrix occurs through the bulk nucleation and three-dimensional growth of nuclei growing with constant rate.
