開示されており、それなりに大きな成果をあげている。(Prior art) In general, alloys mainly composed of iron and nickel include:
Permalloy alloy, which is a soft magnetic material, 42 alloy for IC lead frames, low thermal expansion amber alloy, 42 for glass sealing
-6 alloy etc. are known. A common drawback of these alloys is that they have poor hot workability, resulting in low yields during forging and hot rolling, which is a manufacturing problem. In order to improve this defect seen during manufacturing, a method of improving hot workability by using a material to which B is added has been disclosed in Japanese Patent Application Laid-open No. 159157/1983, etc. has achieved great results.

た。(Problem to be solved by the invention) However, the addition of B to the material alloy has a large effect on the properties of the alloy (for example, it greatly reduces the magnetic properties and adhesion with the coating material (glass), etc.). Therefore, the amount of B added is limited, and as a result, it has not been possible to achieve a sufficient improvement in hot workability.

。An object of the present invention is to improve the problems faced by the above-mentioned conventional techniques and to propose an advantageous method for producing an iron-nickel alloy that has excellent hot workability and quality characteristics.

We propose a method for producing an iron-nickel alloy, which is characterized by performing a B-removal treatment by heat-treating a hot-rolled material or a cold-rolled material containing wt% of B in a non-oxidizing atmosphere. do.

付与するようにした技術である。(Function) The method according to the present invention preferably includes hot working an alloy in which a predetermined amount of B is added to the molten metal at the time of agglomeration, and then heat-treating the alloy. B
This is a technology that reduces the amount of magnetic flux and gives products the necessary qualities such as magnetic properties.
まず、本発明で用いる出発材料は、Ｎｉを３３〜８５ｗ
ｔ％（以下、単に「％」で略記する）の範囲で含み、Ｂ
を０．００１〜０．１％の範囲で含み、残部が実質的に
Ｆｅおよび不可避不純物よりなるものを用いる。First, the starting material used in the present invention contains 33 to 85w of Ni.
t% (hereinafter simply abbreviated as "%"), B
in the range of 0.001 to 0.1%, with the remainder essentially consisting of Fe and unavoidable impurities.
ここで、Ｎｉ含有量の下限を３３％としたのは、マルテ
ンサイトが析出しやすく熱膨張率、磁気特性とも不安定
となるからである。一方、含有量上限の８５％はこの値
を超えるものではもともと熱間加工性が良好でＢ添加が
不必要となるので限定した。Here, the lower limit of the Ni content is set to 33% because martensite tends to precipitate and both the coefficient of thermal expansion and magnetic properties become unstable. On the other hand, the upper limit of the content of 85% was set because if it exceeds this value, hot workability is already good and addition of B is unnecessary.
次に、Ｂの含有量については、下限値の０．００１％以
下では熱間加工性改善に対して効果がなく、一方上限と
した０、１％を超えるようでは却って熱間加工性を低下
させるので、０．００１〜０．１％の範囲とした。Next, regarding the B content, if it is below the lower limit of 0.001%, it will not be effective in improving hot workability, while if it exceeds the upper limit of 0.1%, it will actually reduce hot workability. Therefore, the content was set in the range of 0.001 to 0.1%.
なお、本発明においては、上記成分組成の他、鉄合金と
する場合に不可避に含まれる、Ｃ，Ｓｉ。In addition, in the present invention, in addition to the above-mentioned composition, C and Si are unavoidably included when making an iron alloy.

くなりすぎるので１５％を上限とする。Ｍ。If the content of any of the above C, Si, Mr+, P and S exceeds the specified upper limit, hot workability will decrease, and Cr has a lower thermal expansion coefficient in 42N i -6Cr -Fe alloys etc. It is added for the purpose of control and improving sealing properties, but if it exceeds 15%, the magnetic properties will become unstable because it lowers the magnetic transformation point, and the coefficient of thermal expansion will become too large. Therefore, the upper limit is set at 15%. M.
およびＣｕについては、磁気特性の冷却速度感受性をや
わらげるが、それぞれ６％、１５％を超えると逆に磁気
特性を低下させる。Ａｎは、０．５％より多いと清浄度
を下げ、磁気特性を低下させることが分かっている。Cu and Cu soften the cooling rate sensitivity of the magnetic properties, but if they exceed 6% and 15%, respectively, they deteriorate the magnetic properties. It is known that if the amount of An is more than 0.5%, the cleanliness will be lowered and the magnetic properties will be lowered.
さて、上記成分組成の合金造塊材は、鍛造、熱間圧延を
行った後、ホットコイルのまま或いは焼鈍、酸洗を経た
後、またはさらに冷間圧延を行った後、熱処理を行う。Now, after forging and hot rolling, the alloy ingot having the above-mentioned composition is subjected to heat treatment either as a hot coil or after annealing and pickling, or after further cold rolling.

ができる。This heat treatment is carried out in an inert, reducing so-called non-oxidizing gas atmosphere such as Ar, NZ+ Hz, etc. at a temperature of 900 to 130 Hz.
Heat treatment is performed at 0°C for 30 minutes to 4 hours. By this heat treatment, Bq in the alloy is significantly reduced, and the adverse effect on quality due to the addition of a large amount of B can be reduced to a negligible extent.
この加熱処理によってＢを低減させ得る理由は次のよう

It is about 0.01 to 1 torr and does not oxidize Fe, Ni, etc., but since B has a strong bond with oxygen, it is thought to react with this impure gas and become boron oxide or boron hydroxide. . Therefore, the presence of a trace amount of 0□ and H2O in the atmosphere is necessary for the B removal process. Therefore, if the purity of Ar, H2 gas atmosphere or 10
Heat treatment in a high vacuum exceeding -' Torr is not preferred in the present invention because it is expected that sufficient B removal treatment cannot be performed.

However, it has been found that when the alloy is heat treated in hydrogen, an atmosphere according to the method of the present invention, the amount of B in the alloy is reduced and good magnetic properties are obtained.
