对Fe78Si9B13非晶合金进行了连续高电流密度电脉冲和等温退火。采用穆斯堡尔谱研究了处理后非晶态样品的微观结构变化和结晶行为。结果表明，电脉冲处理明显促进了非晶合金的结晶。电脉冲对结晶的影响取决于脉冲电流对非晶合金中原子扩散的刺激。
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.
