摘　　要：采用元素替代法对合金进行成分设计,应用单辊快淬法和非晶晶化方法制备了6种成分的纳米晶合金。利用X射线衍射(XRD)并结合差示扫描量热法(DSC)表征了非晶态软磁合金的非晶形成能力、热稳定性、晶化过程。先后对淬态磁芯分别进行普通热处理和横磁场热处理,对热处理后的磁芯使用型号为MATS-2010SD的软磁直流测试仪和MATS-2010SA软磁交流测试仪检测。试验结果表明,横磁场热处理后Fe_(64)Ni_(12)Si_(13)B_(8)Nb_(2)Cu_(1)合金的初始磁导率为3.247 k,矫顽力为4.217 A/m,0.2 T/100 kHz下的损耗为27.14 W/kg,获得了具有低磁导率、低矫顽力和低损耗的软磁合金。The alloy composition design was performed by element substitution method.Six kinds of nanocrystalline alloys were prepared by single roll rapid quenching and amorphous crystallization methods.The glass forming ability,thermal stability and crystallization process of amorphous soft magnetic alloys were characterized by X-ray diffraction(XRD)and differential scanning calorimetry(DSC).The quenched magnetic cores were treated by ordinary heat treatment and transverse magnetic field heat treatment.The soft magnetic DC tester(MATS-2010SD)and soft magnetic AC tester(MATS-2010SA)were used to test the core after heat treatment.The experimental results show that the initial permeability of Fe_(64)Ni_(12)Si_(13)B_(8)Nb_(2)Cu_(1)alloy is 3.247 k,the coercivity is 4.217 A/m,and the loss is 27.14 W/kg at 0.2 T/100 kHz.The soft magnetic alloy with low permeability,low coercivity and low loss is obtained.
