利用单铜辊甩带法制备Fe83SixB16-xCu1(x=4、5、7、9、10、11、12、14)合金带材,采用X线衍射仪(XRD)、差示扫描量热仪(DSC)和振动样品磁强计(VSM)对FeSiBCu系列合金的相结构、热稳定性和软磁性能进行表征,探讨了Si、B元素之间的比例对FeSiBCu系列合金带材的非晶形成能力和软磁性能的影响。结果表明,在整个FeSiBCu系列合金带材中,当Si、B元素之间的比例Si/B=2.2时,其X射线衍射图谱中显示的漫头峰最宽,非晶形成能力最好;在DSC测试中该比例的晶化峰温度最低;通过VSM所测出的磁滞回线中得到其饱和磁化强度最大,达168.9emu/g。
The Fe83SixB16-xCu1 (x = 4, 5, 7, 9, 10, 11, 12, 14) alloy strip was prepared by single copper roll rejection method and characterized by X-ray diffractometry (XRD), differential scanning calorimeter DSC) and vibrating sample magnetometer (VSM) were used to characterize the phase structure, thermal stability and soft magnetic properties of the FeSiBCu alloy. The effects of Si and B ratios on the amorphous formation ability of the FeSiBCu alloy strip And soft magnetic properties. The results show that in the whole FeSiBCu alloy strip, when the ratio Si / B between Si and B is 2.2, the XRD patterns show the highest peak width and the best amorphous formation ability. The crystallization peak temperature was the lowest in the DSC test; the saturation magnetization was found to be 168.9 emu / g in the hysteresis loop measured by VSM.
