【摘要】 研究了普通退火对非晶Fe78Si9B13合金铁芯电感的影响。实验发现:在不同退火温度(450~490℃)非晶合金铁芯的电感均随退火时间的延长单调下降;退火温度越低,电感下降的速率越小。合金经480℃×60min退火,有适当数量的-αFe(Si)晶体相析出后,可呈现良好的恒导磁特性,形成横向感生磁各向异性;非晶合金铁芯具有较低的电感,很强的抗直流偏磁场能力和良好的恒电感特性。更多还原

【Abstract】 The effects of normal annealing on the inductance for amorphous Fe₇₈Si₉B₁₃ alloy cores have been investigated.It was found that the inductance of amorphous alloy cores decreases all monotonously with increasing annealing time at different temperatures（450～490℃） and the lower annealing temperature,the smaller decreasing rate of inductance.When a moderate amount of crystallineα-Fe（Si） phase are precipitated for the alloy annealed at 480℃,60min,the good constant permeability property appears and transversal induced magnetic anisotropy could develop.The amorphous alloy cores having lower inductance exhibit a large ability against direct bias magnetic field and the good constant inductance property.更多还原
