摘　　要：研究了升温速率及冷却方式对1K107B铁基纳米晶磁芯的电感量和磁导率的影响。结果表明,采取较高的升温速率可以有效提高磁芯高频下的电感量及有效磁导率,在f=100 k Hz时其电感量为0.055 m H,有效磁导率为55720;冷却过程中采取随炉空冷的方式可以大幅度提高磁芯磁性能,在f=1 k Hz时其电感量为0.148 m H,有效磁导率为148950;在f=100 k Hz时其电感量为0.066 m H,有效磁导率为66920。The effects of heating rate and cooling ways on the inductance and permeability of 1 K107 B iron-based nanocrystalline cores were studied. The results show that, the higher heating rate can effectively improve the inductance and the effective permeability of the core under high frequency. The inductance and the effective permeability of the core under the 100 k Hz testing frequency is 0.055 m H and 55720 respectively. The furnace gas cooling can greatly improve the magnetic properties of the magnetic core. The inductance and effective permeability under the 1 k Hz testing frequency are 0.148 m H and 148950 respectively. If test frequency is 100 k Hz, they are 0.066 m H and 66920 respectively.
