Rezumat:

The non‐isothermal crystallization kinetics of Fe60Gd5Cr15B20 amorphous alloys is investigated by differential thermal analysis (DTA). The analysis suggests that the crystallization of Fe60Gd5Cr15B20 amorphous alloys is based on two processes characterized by the activation energies εkl  =  3.17±0.57 [eV] and εkl  =  2.55 [eV], respectively. By X‐ray diffraction (XRD) and Mossbauer Spectroscopy (MS) we identified the crystalline phases which appeared during the non‐isothermal crystallization.
