摘要：
In this study, the temperature-heating rate diagram of the main crystallization process of two metallic glasses, Fe(74)Ni(3.5)Mo(3)B(16)Si(3.5) and Fe(41)Ni(38)Mo(3)B(18,) was obtained from one experimental differential scanning calorimetry (DSC) scan and the knowledge of their activation energy as determined by an isoconversional method. A good concordance was observed between the diagram curves obtained by calculation (isoconversional approach) and the experimental data, which verifies the reliability of the method and the validity of the kinetic approach in these alloys.
