用されている。Conventionally known alloys with high saturation magnetic flux density include Fe containing approximately 35 to 50% Co by weight.
-Co alloys, especially Fe-35%Co
The alloy Fe-50%Co alloy is well known. These alloys have a high saturation magnetic flux density of 24000G or more and have excellent coercive force, but 50% Co
Because it forms a regular lattice with a composition centered on Subsequently, research was carried out to improve the cold workability of the Fe-Co alloy mentioned above, and it was found that V could suppress the formation of an ordered lattice in the Fe-Co alloy and improve the cold workability. Then,
A Fe-49%C0-2%V alloy was developed and is still in use today.

となり問題となっていた。However, the addition of ■ increases the ductility of this alloy,
Although cracks were less likely to occur during cold working, the deformation resistance was high, and the amount of processing per cold working such as cold rolling had to be reduced, resulting in poor productivity. Furthermore, due to the high Co content and poor immersion in hot water during solidification after melting, the surface of the steel ingot becomes uneven, resulting in a large amount of skin scraping on the surface of the steel ingot, resulting in higher prices and impeding the expansion of applications. It was a problem.

きたので、大幅なコストダウンを実現したものである。The content is 51.35χ (by weight ratio, which is the composition of the regular lattice)
It was considered that it was necessary to lower the degree of regularity by lowering the atomic number ratio from 50χ). In addition, in order to minimize the decline in magnetic properties and improve cold workability, it is necessary to add another component that can reduce regularity and improve cold workability with a smaller amount than ■. I thought it was necessary to find an element. Therefore, the saturation magnetic flux density of Co content is
By reducing the amount to a level comparable to that of 49%Co-2%■ alloy, the degree of order is lowered, and by adding various alloying elements, the degree of order decreases per unit addition and the cold workability improves. The degree of improvement was investigated. As a result, Zr5Ti,
The five elements Nb, Ta, and B have a much greater effect than ■, and a small addition amount of 0.30 to 0.40% from 0°005 results in a greater reduction in regularity than when adding 2% ■. It has been found that a large effect of improving cold workability can be obtained accordingly. In particular, since Zr has a great effect of improving cold workability, it is added to Fe-Co alloys by 0.005 to 0.3.
Add 0% Zr, add Ti, Nb, TaX as necessary
By adding B, we succeeded in improving cold workability without lowering the saturation magnetic flux density compared to the Fe-49%Co-2%V alloy. In addition, by discovering an element that can improve cold workability with a smaller addition amount than in (2), it is possible to minimize the decrease in saturation magnetic flux density, and moreover, compared to conventional Fe-49%Co
Compared to the -2% ■ alloy, the amount of Co could be significantly reduced, resulting in a significant cost reduction.

This has been confirmed.

次に、本発明である冷間加工性に優れたＦｅ−Ｃｏ系合
金の成分組成の限定理由について説明する。Next, the reasons for limiting the composition of the Fe--Co alloy having excellent cold workability according to the present invention will be explained.
Ｃｏ；１５〜３３％未満

ともにコストも高くなる。Co: Less than 15% to 33% Co is an essential basic element for the present invention to ensure excellent saturation magnetic flux density, and Fe-49%Co
-2% ■ In order to obtain a saturation magnetic flux density equal to or higher than that of the alloy, it is necessary to contain 15% or more. but,
When the content is 33% or more, the cold deformation resistance increases and the cost also increases.
Ｚｒ；０．００５％〜０．３０％
Ｚｒは本発明において最も重要な元素であり、冷間加工
性を大幅に改善する効果を有し、その効果を得るために
は０．００５％以上の含有が必要である。しかし、過剰
に含有させると飽和磁束密度が低下するのでその上限を
０．３０％とした。Zr; 0.005% to 0.30% Zr is the most important element in the present invention, and has the effect of greatly improving cold workability. Containment is necessary. However, if it is contained in excess, the saturation magnetic flux density decreases, so the upper limit was set at 0.30%.
Ｃ＋Ｎ；０．０２％以下
Ｃ，Ｎは熔解、製鋼時に不純物として混入するが、飽和
磁束密度を低下させるのでできるだけ低減することが望
ましく、その上限を０．０２％とした。C+N: 0.02% or less C and N are mixed as impurities during melting and steel manufacturing, but since they lower the saturation magnetic flux density, it is desirable to reduce them as much as possible, and the upper limit is set at 0.02%.
５ｉｌｏ、０３〜０．３０％
Ｓｉは鋼塊の表面肌を改善し、歩留向上に効果のある元
素であり、その効果を得るためには０゜０３％以上含有
させる必要がある。しかし、多量の含有は飽和磁束密度
を低下させるため、その上限を０．３０％とした。5ilo, 03 to 0.30% Si is an element that is effective in improving the surface texture of steel ingots and increasing yield, and in order to obtain this effect, it must be contained in an amount of 0.03% or more. However, since a large amount of content lowers the saturation magnetic flux density, the upper limit was set at 0.30%.

b. Like Zr, Ta is an element that improves cold workability, and in order to obtain this effect, 0.005% of all three elements is required.
It is necessary to contain the above amount. However, when the content exceeds 0.30%, the saturation magnetic flux density decreases, the transformation temperature decreases, and the coercive force also deteriorates.
Ｂ；０．０１〜０．４０％
Ｂは結晶粒界に集まり、粒界の結合力を増すことにより
冷間加工性を改善する元素である。前記効果を得るため
には０．０１％以上含有させることが必要である。しか
し、０．４０％を越えて含有させるとＴｉ、Ｎｂ、Ｔａ
と同様に飽和磁束密度と保磁力が悪化する。B; 0.01 to 0.40% B is an element that gathers at grain boundaries and improves cold workability by increasing the bonding strength of the grain boundaries. In order to obtain the above effect, it is necessary to contain 0.01% or more. However, if the content exceeds 0.40%, Ti, Nb, Ta
Similarly, the saturation magnetic flux density and coercive force deteriorate.
