折像を検出することはなかった。An internal water-cooled Cu-Be alloy in which nitrogen is added to the alloy by blending iron nitride in a nitrogen gas stream, and molten alloys having the above-mentioned compositions with different nitrogen contents are rotated at a circumferential speed of 30 m/sec. It is injected from the slit of a quartz nozzle onto the roll surface, solidified by ultra-rapid cooling, and has a thickness of 25 μm to 30 μm.
An amorphous alloy ribbon with a width of 10 μm and a plate width of 10 μm was produced. Alloy ribbons with a maximum nitrogen content of 0.15 atomic % were prepared and examined by X-ray diffraction, but no diffraction images showing a crystalline structure were detected in any of them.

（作 用）
本発明非晶質合金における合金組成の限定理由を以下に
説明する。(Function) The reason for limiting the alloy composition in the amorphous alloy of the present invention will be explained below.
Ｎ量の含有量をＲｅ、 Ｃｏ、 Ｎｉの合計量に対して
、０．５％ないし４０％としたのは、０．５％未満では
透磁率の向上に効果がなく、また４０％を超えると透磁
率および飽和磁束密度がともに低下するからである。The reason why the N content is set to 0.5% to 40% with respect to the total amount of Re, Co, and Ni is that if it is less than 0.5%, it is not effective in improving magnetic permeability, and if it exceeds 40%. This is because both magnetic permeability and saturation magnetic flux density decrease.
Ｓｉ量は１％未満では耐熱性の向上に顕著な効果がなく
、また２０％以上になると、非晶質合金の形成が困難に
なるので１％ないし２０％とした。If the amount of Si is less than 1%, there will be no significant effect on improving heat resistance, and if it exceeds 20%, it will be difficult to form an amorphous alloy, so it is set to 1% to 20%.
Ｂ量が６％未満および２５％以上では非晶質合金の形成
が困難になるばかりでなく、高透磁率を得ることができ
ないので、６％ないし２５％とした。If the amount of B is less than 6% or more than 25%, not only will it be difficult to form an amorphous alloy, but also high magnetic permeability cannot be obtained, so it is set to 6% to 25%.
Ｎ量が０．００８ ％未満では不可避不純物としてのＮ

０８ ％ないし０．１ ％とした。If the amount of N is less than 0.008%, N will become an unavoidable impurity.
The effect of N addition was not recognized. Moreover, if it exceeds 0.1%, not only will the coercive force increase, but the surface quality of the manufactured ribbon will be poor.

When N and Cr were added, improvements in tensile strength, Vickers hardness, and corrosion resistance were observed, especially in the coexistence with N.
It has been found that deterioration in magnetic properties such as magnetic permeability can be suppressed.
