摘要：

The crystallization kinetics of the amorphous alloy Fe67Co18B14Si1 (Metglas 2605CO) has been studied using the FMR technique. The Avrami exponent, n, and the effective activation energy, E-c, were determined for the primary and polymorphic crystallization stages. The results for the primary stage (n=1.00, E-c=230 kJ mol(-1)) are consistent with diffusion-controlled growth with a nucleation rate close to zero; for the polymorph stage, the results (n=1.55, E-c=365 kJ mol(-1)) are consistent with diffusion-controlled growth with a constant nucleation rate.
