Study on Preparation of FeSiBPCu Amorphous Nanocrystals and Soft Magnetic Properties

主要采用元素替代的方法对合金进行成分设计,应用单辊旋淬法和非晶晶化法制备了六种Fe_(83)Si_4B_(12-x)P_xCu_1(x=0,2,4,6,8,10)非晶纳米晶合金。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。采用振动样品磁强计(VSM)测量非晶合金和纳米晶合金的磁性能,系统研究了合金元素和退火工艺对非晶纳米晶软磁合金结构和性能的影响,获得了具有高饱和磁化强度和低矫顽力的软磁合金材料。

The element substitution method was adopted to make composition design of the alloy,as well as melt-spin method and amorphous crystallization method were adopted for preparation of six Fe83SiB12-xPxCu1（x = 0,2,4,6,8,10） amorphous nanocrystalline alloy. In addition,X-ray diffraction（XRD） and differential scanning calorimetry（DSC） were used to characterize the amorphous forming capacity,thermal stability and crystallization process of amorphous soft magnetic alloys. Moreover,vibrating sample magnetometer（VSM） was applied to measure the magnetic property of amorphous alloys and nanocrystalline alloy,which systemically studied the impact of alloy elements and annealing process on the properties and performance of amorphous ananocrystalline soft magnetic alloy structure.The soft magnetic alloy material of high saturation magnetization and low coercive force was obtained.
