Method for improving the magnetic properties of Fe-based amorphous-alloy thin strip |
| 摘要 |
The watt-loss of the Fe-based amorphous alloy-thin strip is decreased by locally melting the surface of thin strip and again vitrifying the melting parts. In addition, the magnetic flux density is enhanced by annealing the thin sheet after the local melting.
