چکیده: In order to investigate the crystallization behavior of the Co67Fe4Cr7Si8B14 amorphous
metallic alloy, ribbons of this alloy were prepared by planar flow melt spinning process (PFMS).
Differential scanning calorimetery (DSC) and differential thermal analyzer (DTA) were used to
analyze the thermal properties and crystallization behavior of the samples at three heating rates of
10, 20 and 30 º C/min. The experimental data were fitted to the Avrami model to determine the
crystallization behavior. The results showed that the crystallization exotherm became wider and
shifted toward a higher temperature range as the heating rate increased. The Avrami analysis also
showed that n is about 1, which is related to the same transformation mechanism at different heating
rates. The Kissinger method was used to determine the activation energy for the first crystallization
peaks. The measured value is approximately 332.67 kJ/g.
