Abstract: In order to investigate the crystallization behavior of the amorphous phase in the Co67Fe4Cr7Si8B14alloy system, the ribbons of this alloy were prepared by planar flow melt spinning (PFMS). Differential scanning calorimetery (DSC) was used to analyze the thermal and crystallization behavior of the samples at different heating rates of 10 and 30 . The crystallization kinetic was done by a direct fitting of the experimental data to Avrami model. The results of this study showed that the crystallization exotherm became wider and shifted toward a higher temperature range when the heating rate increased. The Avrami exponent (n) was independent of the heating rate and implied the same transformation mechanism as well. Also, the activation energy was determined as 367.6 Kj/g by the means of Kissinger analysis.
