【発明の詳細な説明】
（産業上の利用分野）
この発明は、透磁率や保磁力のみならず、飽和磁束密度
および磁歪特性にも優れた軟磁性材料に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a soft magnetic material that is excellent not only in magnetic permeability and coercive force but also in saturation magnetic flux density and magnetostriction properties.
変圧器やチョーク、磁気ヘッドなどの用途に用いられる
磁性材料としては、単に透磁率や保磁力に優れるだけで
なく、飽和磁束密度さらには磁歪特性も良好であること
が必要とされる。というのはけ歪が大きいと透磁率の低
下を招き、加えてとくに電力用変圧器として用いた場合
には騒音発生の原因ともなるからである。また飽和磁束
密度が小さいと小型化を図れないという不利がある。Magnetic materials used in applications such as transformers, chokes, and magnetic heads are required not only to have excellent magnetic permeability and coercive force, but also to have good saturation magnetic flux density and magnetostriction properties. This is because a large brush strain leads to a decrease in magnetic permeability and, in addition, causes noise generation, especially when used as a power transformer. Furthermore, if the saturation magnetic flux density is low, there is a disadvantage that miniaturization cannot be achieved.
しかしながら一般に、飽和磁束密度とけ歪特性とは相反
する性質とされ、上記の如き高透磁率磁性材料において
、従来両特性を満足させることはできなかった。However, in general, the saturation magnetic flux density and the strain characteristics are considered to be contradictory properties, and conventionally it has not been possible to satisfy both characteristics in the above-mentioned high permeability magnetic materials.
（従来の技術）
たとえば変圧器等の鉄心材料として汎用されているけい
素鋼板を例にとると、Ｓｉ含有債が少なければ高い飽和
磁束密度が得られるけれども磁歪は大きく、一方Ｓｉ含
有量を６．５ｗｔ％程度まで高めれば磁歪はほぼ０にす
ることができるけれども、逆に飽和磁束密度はＳｉｌの
増加に伴って低下する。(Prior art) For example, if we take silicon steel sheets that are commonly used as iron core materials for transformers, etc., if the Si content is small, a high saturation magnetic flux density can be obtained, but the magnetostriction is large; Although the magnetostriction can be reduced to almost 0 by increasing it to about .5 wt%, on the contrary, the saturation magnetic flux density decreases as Sil increases.
また磁心材料として用いられるセンダスト合金は、磁歪
はほぼ０ではあるけれども飽和磁束密度は低い。しかも
この合金は、非常に脆いために、塑性加工が極めて困難
という不利もある。Furthermore, although the Sendust alloy used as the magnetic core material has a magnetostriction of almost 0, its saturation magnetic flux density is low. Moreover, this alloy has the disadvantage that it is extremely difficult to plastically work because it is extremely brittle.
（発明が解決しようとする問題点）
このように従来は、高透磁率磁性材料において高い飽和
磁束密度と小さい磁歪を兼ね備えたものは見当たらず、
その開発が望まれていた。(Problems to be Solved by the Invention) As described above, conventionally, there has been no high permeability magnetic material that has both high saturation magnetic flux density and low magnetostriction.
Its development was desired.
この発明は、上記の要請に有利に応じるもので、高透磁
率および低保磁力だけでなく、飽和磁束密度や磁歪特性
にも優れた軟磁性材料を提案することを目的とする。The present invention advantageously meets the above requirements, and aims to propose a soft magnetic material that not only has high magnetic permeability and low coercive force, but also has excellent saturation magnetic flux density and magnetostriction properties.

81 and Si are γ-loop type, and B+ If +
Nb+Ta and Zr have a narrow T and are both equally effective in improving the soft magnetic properties when used in combination with Sn. However, whether the above elements are used alone or in combination, the amount added is 0.
If the amount is less than 0.05%, a sufficient addition effect cannot be expected, while if it exceeds 10.0%, there is a strong possibility that the saturation magnetic flux density will decrease, so the amount added is limited to a range of 0.05 to 10.0%. did.
この発明に従う軟磁性材料は、所定の形状に鋳込んだま
までも勿論使用されるけれども、薄板として使用される
場合が多い。Although the soft magnetic material according to the present invention can of course be used as it is cast into a predetermined shape, it is often used as a thin plate.
ところがこのＦｅ −Ｓｎ系合金は、非常に脆いため従
来のような冷間圧延などによる薄板化は極めて難しい。However, this Fe-Sn alloy is very brittle, and therefore it is extremely difficult to make it into a thin sheet by conventional cold rolling.

単ロール法、双ロール法および回転ドラム法など従来公
知のいずれの方法をも使用できる。However, this point can be solved by employing a rapid thinning method, that is, a method for directly manufacturing thin metal sheets from molten metal. Here, the quenching method is as follows:
Any conventionally known method can be used, such as a single roll method, a twin roll method, and a rotating drum method.
かくして得られた急冷凝固直後の状態でも十分満足のい
く軟磁気特性が得られるけれども、その後に焼鈍処理を
施すことによってより一層の特性向上がもたらされる。Although sufficiently satisfactory soft magnetic properties can be obtained in the state immediately after the rapid solidification obtained in this manner, further improvement in properties is brought about by performing an annealing treatment thereafter.
かかる焼鈍処理において、処理温度が８００℃に満たな

で、８００〜１３００℃の範囲で焼鈍することか好まし
い。In such annealing treatment, if the treatment temperature is less than 800°C, there is a disadvantage that it requires a long time, while if it exceeds 1300°C, the surface of the ribbon may melt depending on the alloy system, so Annealing is preferred.
（作 用）
Ｆｅ −Ｓｎ系合金において、と（に高い飽和磁束密度
と小さい磁歪が併せて得られる理由は、まだ明確に解明
されたわけではないが、次のとおりに考えられる。(Function) The reason why both high saturation magnetic flux density and small magnetostriction are obtained in Fe-Sn alloys has not yet been clearly elucidated, but it is thought to be as follows.
Ｆｅ合金において磁歪を零にする添加元素の中で、Ｓｉ
は１２％であるがＳｎでは３〜４％である。ＳｉもＳｎ
も非磁性元素であるから、添加量の増大とともにＦｅの
強磁性すなわち飽和磁束密度を低下させる。Among the additive elements that make magnetostriction zero in Fe alloys, Si
is 12%, but it is 3 to 4% for Sn. Si and Sn
Since Fe is also a non-magnetic element, the ferromagnetism of Fe, that is, the saturation magnetic flux density, decreases as the amount added increases.
従って、添加量が少ない程、飽和磁束密度の低下を制限
できる。Therefore, the smaller the amount added, the more the reduction in saturation magnetic flux density can be restricted.
