- 論文の詳細を見る
Amorphous alloys of Fe-Co-Ni-Si-B system with a wide composition have been produced by a conventional rapid quenching method, and their soft magnetic properties have been examined. The Fe-rich alloys having a high saturation magnetization (〜1.6×10^4 G) exhibit a rectangular-type B-H hysteresis loop with low coercive force of about 0.01 Oe when the alloys are subjected by a magnetic field cooling. On the other hand, the Co-rich non-magnetostrictive alloys exhibit a high effective permeability ( 50 - 100×10^3 ) at the initial magnetization and audio frequency range. The detailed compositions and heattreatments in obtaining the best soft magnetic properties, and the characteristics which may be interest in engineering applications will be reviewed.
