摘要
利用单铜辊甩带法制备(Fe_(1-x)Ni_(x))_(83)Si_(1)B_(16)(x=0,0.1,0.2,0.3,0.4,0.5)非晶合金带材,并进行退火处理。采用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、差示扫描量热仪(DSC)、振动样品磁强计(VSM)、直流/交流磁化特性自动测试分析仪(BH)、维氏硬度计、Instron机械试验机分析研究不同的Fe/Ni比例对于FeNiSiB合金带材的非晶形成能力、软磁性能和力学性能的影响。结果表明随着Ni元素不断替换Fe元素,FeNiSiB合金带材会有晶化的趋势,并且有α-Fe相析出,第一晶化温度T x1不断降低,力学性能有所提升,维氏硬度和抗拉强度分别高达770.0和2452 MPa。适当的Fe/Ni比例会使得材料的软磁性能显著提升,其中(Fe_(0.8)Ni_(0.2))83-Si 1B 16在退火处理后饱和磁感应强度Bs为1.62 T,矫顽力Hc仅为0.5 A/m,初始磁导率μi为33000。
(Fe_(1-x)Ni_(x))_(83)Si_(1)B_(16)(x=0,0.1,0.2,0.3,0.4,0.5)amorphous alloy ribbons were prepared and annealed using single copper roll dump strip method.X-ray diffractometer(XRD),scanning electron microscope(SEM),differential scanning calorimeter(DSC),vibrating sample magnetometer(VSM),DC/AC magnetisation properties automatic test analyser(BH),Vickers hardness tester,and Instron Mechanical Tester were used to analyze and study the effects of different Fe/Ni ratios on the amorphous formation ability,soft magnetic properties and mechanical properties of FeNiSiB alloy ribbons.properties and mechanical properties of FeNiSiB alloy ribbons.The results show that the FeNiSiB alloy ribbons have a tendency to crystallise and precipitateα-Fe phases with the replacement of Fe by Ni.The first crystallisation temperature T x1 decreases,and the mechanical properties are improved,with the Vickers hardness and tensile strength as high as 770.0 and 2452 MPa,respectively.It is found that the soft magnetic properties of the materials are improved by an appropriate Fe/Ni ratio,with samples being annealed at the same time as those with(Fe_(0.8)Ni_(0.2))83 Si 1B 16 sample has a saturated magnetic induction B s of 1.62 T after annealing treatment,a coercivity H c of only 0.5 A/m,and an initial permeabilityμi of 33000.
