Influence of Annealing Process on the Magnetic Induction Effect of FeSiB Amorphous Alloy Ribbons
The influences of frequency, magnetic field density, importing waveform and annealing process on the rangeability of Fe78Si9B13 amorphous alloy ribbon’s magnetic induction effect were studied. The results showed that the rangeability increased with the magnetic field density increased when frequency below 75 kHz, but decreased with the field density increased when frequency over 75 kHz. Compared with quenched ribbons, the rangeability increase after annealed, and the rangeability reached maximum annealed at 300°C for 1.5 hours. When the input waveform is 75 kHz positive pulse and field intensity is 358A/m, the rangeability the quenched ribbons was 2.27V but it reached to 2.85V after annealed at 300°C for 1.5hours.
