摘要：

In this paper, the effect of adding Permalloy (<15 mu m) on Fe83.5Si7.5B5Cr4 amorphous nanocrystalline magnetic powder (<50 mu m) was studied. The best stress relief annealing temperature were revealed at the same time. The results showed that the addition of Permalloy will significantly affect the soft magnetic properties of Fe-based amorphous nanocrystalline powders. Compared to the Fe83.5Si7.5B5Cr4 amorphous nanocrystalline powder, the saturation magnetization of composite powders obviously increased (by 9.8-17.1%). When Permalloy content was 15wt%, the sample had the highest effective permeability, which increased by 21.6% (f=200kHz). At the same time, the core loss was also reduced by 5.3% (Bm=40mT, f=200kHz) when Permalloy content was 10wt.%. In addition, the magnetic powder core had the highest effective permeability and the lowest core loss when the stress relief annealing temperature was set to 773K.
