があった。It is made of a metal-non-metal alloy based on the non-metallic 9m of the 41 iron core, and it was considered that a metal-non-metal alloy could also be used for the 41 iron core. However, amorphous alloys made by ultra-quenching are thermally unstable because they are in a quasi-equilibrium state, and at relatively low temperatures of 100 to 150°C, they may not move, diffusion of nonmetallic elements, segregation, or structural relaxation. There are drawbacks such as deterioration of magnetic properties and deterioration of mechanical properties such as embrittlement due to the influence of heat.
There were problems such as difficulty in handling due to beta-ization and brittleness.

を小さくできない等の欠点がある。On the other hand, the wound core using the conventionally used I'#-Iv4 alloy has a drawback that the core shape cannot be made small because the loss is large and the calorific value is large.

KHz (1) Shows the change in power supply efficiency over time when using Kame IIK. The wound core 9 made of a metal-metal amorphous alloy shows almost no deterioration in power supply efficiency even after 2000 hours have passed. On the other hand, the efficiency of the metal-nonmetallic amorphous alloy used was reduced by about 2 points after 2000 hours. It can thus be seen that the wound core made of a metal-metal amorphous alloy is thermally stable and is excellent as a wound core.

巻鉄心の安定性と脆化による扱いにくさを改善した。On the other hand, wound cores made of metal-nonmetallic amorphous alloys are thermally unstable and difficult to handle due to K, such as embrittlement. Therefore, we used a non-embrittling metal-metallic amorphous alloy as the core material for its thermal stability, which improved the stability of the core and the difficulty in handling due to embrittlement. .
