Abstract
Crystallization of amorphous alloy Co68Fe4Cr4Si13B11 was analyzed by X-ray diffraction, transmission electron microscopy and differential scanning calorimetry. The polymorphic crystallization of cobalt and eutectic crystallization of cobalt and Co3B were observed during the crystallization of the alloy. The Avrami constant was found to be 1.65, indicating that crystallization of the glass is dominated by three-dimensional diffusion controlled growth with a near zero nucleation rate. The onset of crystallization of Co68Fe4Cr4Si13B11 alloy was found to be above 773 K which was higher than those of Cr-free Co-rich amorphous alloy. The magnetic property of crystallized samples was also correlated to the microstructure during crystallization.
