| 摘 要： | 对非晶Ｆｅ（７８）Ｓｉ９Ｂ（１３）合金进行了连续高密度超短脉冲电流处理和对应的等温退火处理，用Ｍｏｓｓｂａｕｅｒ谱学技术研究处理后非晶试样的微观结构变化与晶化行为．实验结果表明，脉冲电流处理明显促进非晶合金的晶化，电脉冲对晶化的影响取决于脉冲电流对非晶中原子扩散的激励作用．

| Abstract: | 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. |
