い憾みがあつた。 Constant magnetic permeability is a property in which the magnetic permeability does not strongly depend on the magnitude of the magnetic field H and is almost constant. Taking advantage of this characteristic, it is used as the magnetic core of wave circuits of communication equipment, thyristor protection circuits, pulse transformers, etc. has been done. A Fe-60Ni alloy called isoparm is well known as a material having such characteristics. However, this material has a narrow constant magnetic permeability range of 10 Oe at most, making it difficult to use in a wide range of applications.

A thin strip is produced by melting an alloy containing 13 to 25% of a metalloid such as and quenching it in an oxidizing atmosphere (for example, in the air), or after producing a thin strip as described above, the thin strip is produced. The present invention relates to a method for producing an amorphous alloy with excellent constant magnetic permeability, which is characterized by annealing the strip at 250° C. to a crystallization temperature for 1 to 120 minutes.

鈍することによつて製造する。 In order to produce the constant permeability amorphous amorphous alloy of the present invention, first, 0.3 to 5 atomic percent of Al and P are used as raw materials.
A total of 13 to 25 atomic % of one or more metalloids, such as C, B, and Si, with the balance being Fe, is prepared and melted, and then melted using a known liquid quenching method (centrifugal quenching method, twin roll method, single roll method, etc.). ) in an oxidizing atmosphere using
An amorphous ribbon is produced by casting at a cooling rate of °C/sec. Alternatively, after producing an amorphous ribbon as described above, the ribbon is further heated to 250°C.

に、焼鈍すると角形性を示すようになる。 Generally, the magnetic properties of an amorphous alloy ribbon after casting or annealing exhibit a rectangular shape. That is, it is characterized by a large Br/Bs (Br: residual magnetic flux density, Bs: saturation magnetic flux density). Therefore, even if the properties after casting may appear to exhibit constant magnetic permeability due to the influence of residual stress, etc., when annealed to homogenize the properties, they will show squareness.

In the alloy of the present invention, annealing in an oxidizing atmosphere has the effect of expanding the magnetic field range in which constant magnetic permeability is exhibited.

うからである。また半金属の成分範囲はFeを主
成分とする半金属との合金が容易にアモルフアス
化するために13〜25原子％とした。 In the present invention, it is particularly essential to contain 0.3 to 5 atomic % of Al in order to produce constant magnetic permeability. That is, when Al is added to the Fe-metalloid alloy described above and an amorphous alloy ribbon is produced in an oxidizing atmosphere using the liquid quenching method described above, the ribbon exhibits constant magnetic permeability. The reason for this is not clear, but it is presumed that Al is extremely easy to combine with O 2 and therefore an oxide film is formed on the surface of the ribbon even during high-speed quench casting as described above. In addition
The reason why the Al content is set to 0.3 to 5 atomic % is that if it is less than 0.3%, there is no effect, and if it exceeds 5%, the saturation magnetic flux density will be drastically reduced and the range of applications will be limited. The range of the semimetal content was set at 13 to 25 atomic % so that an alloy with a semimetal containing Fe as a main component could easily become amorphous.
なお、前記のように本発明において恒透磁性を
さらに高い磁界まで拡大するためには薄帯を酸化
性雰囲気中で250℃〜結晶化温度の範囲で１〜120
分間焼鈍することが有効である。 As mentioned above, in order to expand the constant magnetic permeability to a higher magnetic field in the present invention, the ribbon is heated at 1 to 120°C in an oxidizing atmosphere at a temperature of 250°C to crystallization temperature.
It is effective to anneal for 1 minute.

トロイダル状に巻き、350℃×30分間真空中で
30Oeの磁界をかけて焼鈍した。この薄帯の直流
磁化特性は焼鈍後においても第１図ａのように優
れた恒透磁性を示した。Example 1 A molten alloy having a composition of Fe 81.3 Si 4 B 14 Al 0.7 (atomic %) was cast at high speed in the atmosphere using a known single roll to produce an amorphous amorphous alloy ribbon with a width of 20 mm and a thickness of approximately 30 μm. did. Wrap approximately 3 m of this thin ribbon into a toroidal shape with an inner diameter of 50 mm, and place it in a vacuum at 350°C for 30 minutes.
It was annealed by applying a magnetic field of 30 Oe. The DC magnetization characteristics of this ribbon showed excellent constant magnetic permeability even after annealing, as shown in Figure 1a.

It can be seen that even after annealing, this shows even better constant magnetic permeability than that of Example 1.
以上説明したように本発明によれば従来のよう
