摘要： 　    低频脉冲磁场处理工艺，使非晶薄带Ｆｅ７８Ｓｉ９Ｂ１３产生纳米晶化，析出α－Ｆｅ（Ｓｉ）纳米相，形成α－Ｆｅ（Ｓｉ）纳米晶与剩余非晶的双相纳米合金。穆斯堡尔谱分析，随着脉冲磁场的强度提高，双相纳米晶合金的晶化相体积分数增加。纳米晶化相α－Ｆｅ（Ｓｉ）的磁致伸缩系数λｃｓ为－１．２８７×１０－４～－１．３４５×１０－４。控制晶化相体积分数，可以使双相纳米晶合金的有效磁致伸缩系数λｅｓ最小，有利于提高双相纳米晶合金的软磁性能。

Abstract: The low frequency pulse magnetic field leads the amorphous thin strip Fe78Si9B13 to produce nano crystallization, precipitating α-Fe (Si) nano phase, and then forming α-Fe (Si) nanocrystalline and residual amorphous dual phase nanocrystalline alloy. Mossbauer spectral analysis, with the strength of the pulse magnetic field, crystallization phase volume fraction of dual phrase nano crystalline alloy increases. The magnetostrictive coefficient λcs CS of nano crystalline phase of α-Fe ( Si ) is negative, with range from- 1.287×10-4 to - 1.345×10-4.Controlling crystallization phase volume ratio can minimize the effective magnetostrictive coefficient λes of dual phase nanocrystalline alloy, benefiting the improvement of dual phase nanocrystalline alloy soft magnetic properties.
