The crystallization kinetics of the amorphous alloy Fe77Gd3B20 were examined under isothermal flash annealing conditions both in air and in a vacuum. Magnetic measurements were used to determine the reaction order (n) and activation energy (Ea), and Mössbauer spectroscopy (MS) was used to identify some resulting crystalline phases.
