Applicability of Kissinger's relation in the determination of activation energy of amorphous Fe 76 Dy 4 B 20 alloy was studied by Differential Scanning Calorimetry (DSC). The activation energy (E a) of crystallization, and Frequency factor (k o)were calculated using three models namely Kissinger, Augis-Bennet and Matusita-Sakka. The average activation energy for primary crystallization of amorphous Fe 76 Dy 4 B 20 alloy using the above three methods is found to be 578.59 kJouls/mole. The
