介绍了基于近自由电子模型的高Fe含量铁基非晶合金的成分设计，指出存在有利于非晶形成的电子浓度（e/a）值。根据良好的e/a值，制备了Fe含量大于83%的Fesingle键B单键P单键Sn非晶合金。采用X射线衍射（XRD）、差示扫描量热仪（DSC）和振动样品磁强计（VSM）研究了Sn对非晶形成能力（AFA）和磁性能的影响。结果表明，矫顽力Hc ~（e/a）关系式与AFA ~（e/a）关系式正好相反。本工作为利用类金属混合物设计具有良好磁性能的铁基非晶合金提供了一种方便的方法。
The composition design for the Fe-based amorphous alloys with high Fe contents is introduced based on the Nearly-Free-Electron model, which indicates that there is a favorable electron concentration (e/a) value for amorphous formation. The Fesingle bondBsingle bondPsingle bondSn amorphous alloys with Fe contents higher than 83% have been prepared based on the favorable (e/a) value. The influences of Sn on the amorphous forming ability (AFA) and magnetic properties are investigated using X-ray diffraction (XRD), differential scanning calorimetry (DSC), and vibrating sample magnetometer (VSM), respectively. The results show that the inflexion of the coercive forceHc~ (e/a) relationship is just contrary to that of the AFA ~ (e/a) relationship. The present work provides a convenient way to design Fe-based amorphous alloys with good magnetic performances by the metalloid admixture according to the favorable (e/a) value.
