EFFECT OF HIGH CURRENT DENSITY LECTROPULSING ON THE CRYSTALLIZATION PROCESS OF AMORPHOUS Fe-Si-B ALLOY
高密度脉冲电流对Fe—Si—B非晶合金晶化过程的影响

The continual high current density electropulsing and comparable isothermal annealing of Fe78Si9B13 amorphous alloy have been carried out. The microstructual change and crystallization behavior of amorphous specimens after treatment were investigated by Mossbauer spectroscopy. The results show that the electropulse treating promotes obviously the crystallization of amopohous alloy. The effect of electropulsing on crystallization is dependent upon the stimulation of pulse current to the diffusion of atoms in amorphous alloy.
