利用透射穆斯堡尔谱 (TMS)对原始态和晶化后非晶软磁合金Fe73.5Cu1 Nb3Si1 3.5B9进行了结构分析。实验结果表明 ,利用连续CO2 激光处理 ,可使样品的非晶带表面产生少量晶化 ,晶化析出相为Fe Si;在样品的非晶相中发生了磁矩重排 ,原子磁矩在面内取向占优。在一定激光辐照工艺条件下 ,可以控制样品的磁矩变化并实现微量晶化 The structure of Fe73.5Cu1Nb3Si1 3.5B9, an amorphous and soft magnetic alloy, was analyzed by transmission Mossbauer spectroscopy (TMS). The experimental results show that continuous CO2 laser treatment can produce a small amount of crystallization on the surface of the amorphous zone of the sample and the precipitated phase is FeSi. The magnetic moment rearrangement occurs in the amorphous phase of the sample, Internal orientation dominant. In a certain laser irradiation process conditions, the sample can control the magnetic moment change and achieve micro-crystallization
