Crystallization kinetics of the amorphous Fe78Si9B13 alloy has been investigated by differential scanning calorimetry in both continuous heating and isothermal annealing modes. The morphology and the growth of different phases during the devitrification process have been studied by transmission electron microscopy and X-ray diffraction. The crystallization of this glass proceedes in two separate stages which can be observed during continous heating as well as during isothermal annealing. It is shown that the lack of complete information about the preparation conditions of the amorphous precursor makes impossible to foresee the stability of the amorphous phase, as well as the phase content, the morphology and the dimensions of the grains during the crystallization process and to compare the results obtained in different investigations.

Abstract

Crystallization kinetics of the amorphous Fe78Si9B13 alloy has been investigated by differential scanning calorimetry in both continuous heating and isothermal annealing modes. The morphology and the growth of different phases during the devitrification process have been studied by transmission electron microscopy and X-ray diffraction. The crystallization of this glass proceedes in two separate stages which can be observed during continous heating as well as during isothermal annealing. It is shown that the lack of complete information about the preparation conditions of the amorphous precursor makes impossible to foresee the stability of the amorphous phase, as well as the phase content, the morphology and the dimensions of the grains during the crystallization process and to compare the results obtained in different investigations.
