利用单铜辊甩带法制备 Fe(86-x) Zr2 Nb2 B10 Nix (x=0、1、3和5)非晶合金带材。采用 X射线衍射仪、差示扫描量热仪、振动样品磁强计以及精密磁性器件分析仪研究Ni元素对FeZrNbB合金带材的非晶形成能力和软磁性能影响。结果表明Ni元素能明显提高该体系合金的非晶形成能力,并使淬火态非晶合金带材的一级起始晶化温度提高；通过合金的退火处理,在Fe(86-x)Zr2 Nb2 B10 Nix 合金体系中含Ni元素的合金带材可以析出最小粒径为12(12.15)nm的α-Fe(a)纳米晶,获得较低的矫顽力为8.1 A/m；其中 Fe85 Zr2 Nb2 B10 Ni1非晶合金带材经过510℃保温20min热处理后可以获得较高的饱和磁感应强度为1.61T,有效磁导率提升到48.4k,矫顽力下降到8.3A/m。
Amorphous Fe(86-x)Zr2Nb2B10Nix(x=0,1,3,5)alloy ribbons were prepared by the single roller melt-spinning method.The effect of Ni addition on glass forming ability and magnetic properties of FeZrNbB alloy ribbons was investigated by X-ray diffraction (XRD),differential scanning calorimeter (DSC),vibrating sample magnetometer (VSM)and precision magnetics analyzer.It was found that the glass foming ability was im-proved and the first crystallization onset temperature (Tx1 )increase with increasing Ni addition.Theα-Fe pha-ses with grain size (D)of 12nm precipitated from alloy ribbons doped Ni,which had a lower Hc of 8.1A/m. The results of Fe85Zr2Nb2B10Ni1 ribbons annealed at 510℃ for 20min showes a higher Bs of 1.61T,effective permeability (μe)of 48.4k,and coercivity (Hc)of 8.3A/m.
