摘要： 用低频脉冲磁场处理非晶合金Co68.15Fe4.35Si12.5B15，用穆斯堡尔谱结合透射电镜对处理前后的试样进行了微结构分析。结果表明，在低频脉冲磁场处理下，非晶合金Co68.15Fe4.35Si12.5B15发生了纳米晶化，晶化析出相为体心立方α-Fe(Si)，析出量为2.743％～23.960％，晶粒尺寸约2～10 nm，且晶化量与磁场强度和脉冲频率均有关系。

Abstract: Amorphous alloys ofCo68.15Fe4.35Si12.5B15  were treated by low frequency pulse magnetic field．The microstructure changes of amorphous specimens before and after treatment were observed by Mssbauer spectra and TEM．The results show that the nanocrystallization of amorphous alloy ofCo68.15Fe4.35Si12.5B15  can occur at low frequency pulse magnetic field．The precipitation content of the nanocrystalline phase α-Fe(Si) with bcc crystal structure is about 2.743％~23.960％，the grain size is 2~10 nm，and the quantity of crystallization have relation with the magnetic field intensity and pulse frequency.

Key words: Low frequency pulse magnetic field, Nanocrystallization, M-ssbauer spectra
