摘要/Abstract

摘要： 研究了新型Fe_80.5Si_7.2B_12.3非晶合金带材在不同退火工艺下的磁性能及磁损耗特性,并与传统的铁基非晶合金Fe₈₀Si₉B₁₁进行了对比。结果表明:新型Fe_80.5Si_7.2B_12.3非晶合金带材比Fe₈₀Si₉B₁₁具有更高的饱和磁感应强度,在励磁磁场强度为3500 A/m下其磁通密度值为1.607 T;在f=50 Hz、B_m=1.4 T下,经无磁场退火处理后其磁损耗高于Fe₈₀Si₉B₁₁,达到0.411 W/kg;经纵磁退火后磁损耗与Fe₈₀Si₉B₁₁基本相当,其值为0.197 W/kg;经横磁退火后损耗仅为0.175 W/kg低于Fe₈₀Si₉B₁₁,而且初始磁导率和恒磁导率均优于Fe₈₀Si₉B₁₁;新型Fe_80.5Si_7.2B_12.3非晶合金带材的最佳退火温度区间(360~400 ℃)与Fe₈₀Si₉B₁₁相当。

Abstract: Magnetic properties and loss characteristics of a new type Fe_80.5Si_7.2B_12.3 amorphous alloy strip under different annealing processes were studied and compared with the traditional iron-based amorphous alloy Fe₈₀Si₉B₁₁.The results indicate that the new type Fe_80.5Si_7.2B_12.3 amorphous alloy strip has a higher saturation magnetic induction intensity than that of Fe₈₀Si₉B₁₁,its magnetic flux density value is 1.607 T under the excitation magnetic field intensity of 3500 A/m.After annealing without magnetic field,its magnetic loss value is higher than that of Fe₈₀Si₉B₁₁,reaching 0.411 W/kg at f=50 Hz and B_m =1.4 T.After longitudinal magnetic annealing,its magnetic loss is 0.197 W/kg and basically equivalent to that of Fe₈₀Si₉B₁₁.After transverse magnetic annealing,its magnetic loss is only 0.175 W/kg,lower than that of Fe₈₀Si₉B₁₁,while the initial permeability and constant permeability are better than that of Fe₈₀Si₉B₁₁.The optimal annealing temperature range (360-400 ℃) of the new type Fe_80.5Si_7.2B_12.3 amorphous alloy strip is equivalent to that of Fe₈₀Si₉B₁₁.
