摘要: 对非晶Ｆｅ７３Ｎｉ５Ｓｉ８Ｂ１４合金分别进行了高密度脉冲电流及真空退火处理．用穆斯堡尔谱学与透射电子显微镜技术研究了处理后非晶的微观结构与晶化行为．实验结果表明，与退火处理相比，高密度脉冲电流产生的“电子风”促进了非晶合金的结构弛豫与晶化．随电流密度显著增加，这一促进效应进一步增强

Abstract: High density electropulsing and vacuum annealing treatments of amorphous alloy Ｆｅ７３Ｎｉ５Ｓｉ８Ｂ１４ have been carried out. The microstructural change and crystallization behavior after treating were investigated by M?ssbauer spectroscopy and TEM techniques. The experimental results show that the "electron wind " induced by high density current promotes the structure of amorphous alloy to be more relaxed and crystallized as compared with annealing treatment. And, The accelerating effect is further enhanced with an increase of current density.
