The kinetic study of the crystallization process of the α-Fe phase from the amorphous Fe 81 B 13 Si 4 C 2 alloy was investigated by DSC and XRD techniques. The kinetic parameters (lnA, E a ) of the investigated process were determined using the Kissinger and isoconversional (model-free) methods. It was established that the α-Fe crystallization process can be described by the JMA (Johnson-Mehl-Avrami) kinetic equation. In accordance with the XRD analysis and the calculated crystallization
