摘　　要：非晶态合金Fe78Si9B1 3样品经短时超短脉冲电流处理 ,发生了结构弛豫 ,用DTA方法及Kissinger方程计算非晶样品的晶化激活能 ,用穆斯堡尔谱学方法研究了试样在电脉冲处理后的无反冲分数的变化 .结果表明 ,随脉冲电流密度和脉冲频率的增加 ,样品的晶化激活能降低 ,穆斯堡尔无反冲分数下降 。Structure relaxation occurred in Fe 78 Si 9B 13 amorphous treated by ultrashort electropulsing. The crystallization activation energy has been calculated by DTA and Kissinger equation.The variety of the zero recoil fraction has been investigated by Mssbauer spectroscopy. The result shows that the crystallization activation energy and the zero recoil fraction decreased when the electropulsing density and frequency increased. It indicated that the atom binding force of Fe 78 Si 9B 13 amorphous decreased accordingly.
