The alloy of the present invention may be used alone or as a cladding material with a base material such as stainless steel.
（従来技術とその問題点）
接触電気抵抗は電気接点材やボタン電池陰極材などの電
気、電子部材にとって重要な特性であり、これらの部材

固な酸化皮膜が存在すると接触電気抵抗は大きくなり、
逆に酸化皮膜が弱いかあるいは酸化皮膜が存在しない場

金属としてはＡｕがよく知られており、電子機器部材等
の接点用として利用されているが高価である。(Prior art and its problems) Contact electrical resistance is an important characteristic for electrical and electronic components such as electrical contact materials and button battery cathode materials. The presence of an oxide film increases the contact electrical resistance,
On the other hand, if the oxide film is weak or does not exist, the electrical contact resistance will be small. Generally, Au is well known as a low contact electrical resistance metal, and is used as a contact for electronic equipment members, etc., but it is expensive.
次いで接触電気抵抗はＡｕに劣るが、Ａｕに代わるより

もつ、Ｎｉ合金は既存合金の中には見当たらないのであ
る。As mentioned above, Ni-plated materials and Ni-clad materials are currently used for applications that require low contact electrical resistance, such as electrical contacts.Although Ni-plated materials have the advantage of having a hard plated surface that is difficult to scratch, Considering future demand developments, the situation is not necessarily satisfactory in terms of productivity or manufacturing costs. Furthermore, Ni cladding materials are suitable for mass production, and there is a possibility of a significant reduction in manufacturing costs depending on improvements in manufacturing methods. However, the Ni used for the cladding has conventionally been Ni201 and Ni200, which have low contact electrical resistance but low hardness (Hv: 80 to 90, respectively).
and Hv: 95-105), these cladding materials are Ni
Because the surface is easily scratched, problems remain for applications that require hardness, such as material for button batteries. on the other hand,
Examples of high-hardness Ni alloys include Inconel alloy, Hastelloy alloy, and Permalloy alloy.
Contains a large amount of Fe, etc., and has high contact electrical resistance. Also,
Permanent Ni and Dura Ni are Ni alloys that increase hardness with small amounts of additive elements, but these also contain Ti and AM that form a strong surface film, so they have high contact electrical resistance and are also highly hard. It requires a long aging treatment to obtain the desired properties, resulting in poor productivity. As described above, for the intended use of the present invention, the surface hardness is about SUS304 (Hv≧140), which is difficult to scratch during molding and use, and the contact electrical resistance is close to that of Ni (2 to 5 mΩ). Among the existing alloys, there is no Ni alloy that has a value (≦10 mΩ) that can maintain its performance sufficiently for practical use.
（発明の目的）
本発明は上記問題点を改善するもので、硬度はＨｖｌ４
０以上、接触電気抵抗は１０ｍΩ以下と硬度が高く、接
触電気抵抗が小さく、しかも、原料の入手が容易で安価
なＮｉ合金を提供することを目的とする。(Object of the invention) The present invention is intended to improve the above problems, and has a hardness of Hvl4.
It is an object of the present invention to provide a Ni alloy which has high hardness, has a contact electrical resistance of 0 or more and a contact electrical resistance of 10 mΩ or less, has a small contact electrical resistance, and is inexpensive because its raw materials are easily available.
（発明の構成）
本発明のＮｉ合金は、重量％で、Ｃ：０．０５〜０．３
％、Ｍｏ：８％以下，Ｎｂ：５．５％以下を含有し、か
つＭｏとＮｂの重量％が次式を満足し、
７≦３．ＩＮｂ＋Ｍｏ≦１７
残部がＮｉと不可避的不純物からなることを第１の特徴
とする。(Structure of the Invention) The Ni alloy of the present invention has C: 0.05 to 0.3 in weight%.
%, Mo: 8% or less, Nb: 5.5% or less, and the weight % of Mo and Nb satisfies the following formula, 7≦3. INb+Mo≦17 The first feature is that the remainder consists of Ni and unavoidable impurities.
また、本発明のＮｉ合金は、第１の特徴に加えて、１０
重量％以下のＦｅを含有することを第２の特徴とする。Further, in addition to the first feature, the Ni alloy of the present invention has 10
The second feature is that it contains less than % by weight of Fe.
（作用）
以下、本発明の特徴を図面を参照しながらその作用と共
に具体的に説明する。(Function) Hereinafter, the features of the present invention will be specifically explained along with its function with reference to the drawings.
先づ、本発明合金で、Ｃ，Ｍｏ，Ｎｂ，Ｆｅ等の必須成
分を限定した理由は次のとおりである。First, the reason why essential components such as C, Mo, Nb, and Fe are limited in the alloy of the present invention is as follows.
Ｃ
炭素は侵入型に固溶し硬化に寄与するとともに，Ｎｂと
の複合添加によりＮｂ炭化物を析出しＮｉを硬くする。C Carbon contributes to hardening by entering into a solid solution in an interstitial manner, and also precipitates Nb carbide when added in combination with Nb to harden Ni.
０．０５重量％未満では硬度の上昇が十分でないので下
限を０．０５重量％とした。また多量の添加は製鋼上の
制約があり、また機械的性質の劣化を招くので、その上
限を０．３重量％とじた。If it is less than 0.05% by weight, the increase in hardness is insufficient, so the lower limit is set to 0.05% by weight. Further, since addition of a large amount causes restrictions in steel manufacturing and also causes deterioration of mechanical properties, the upper limit is set at 0.3% by weight.
Ｍｏ，Ｎｂ
ＭＯは置換型に固溶し、Ｎｉの硬化に寄与する。８重景
％を越える添加は熱間加工性を損なうので、上限を８重
量％とした。Ｎｂは置換型に固溶するとともに、Ｎｂ炭
化物を析出しＮｉを硬化する。ＮｂはＭＯに比べ硬化に
対する寄与は大きいが、接触電気抵抗もより大きくし、
Ｎｂの単独添加では５．５重量％を越えると接触電気抵
抗が１０ｍΩを越えるので、その上限を５．５重量％と
した。またＭｏとＮｂを複合添加する場合、重量％で３
．ＩＮｂ＋Ｍｏ＜７では十分な硬度が得られない。一方
、３．ＩＮｂ＋Ｍｏ＞１７では接触電気抵抗が１０ｍΩ
を越える。したがってＭｏとＮｂの重量％が７≦３．１
Ｎｂ＋Ｍｏ≦１７なる関係式を満足する範囲にある必要
がある。Mo, Nb MO forms a solid solution in a substitutional manner and contributes to the hardening of Ni. Addition of more than 8% by weight impairs hot workability, so the upper limit was set at 8% by weight. Nb forms a solid solution in a substitutional manner, and also precipitates Nb carbide to harden Ni. Nb has a larger contribution to hardening than MO, but it also increases the contact electrical resistance,
When Nb is added alone, if it exceeds 5.5% by weight, the contact electrical resistance exceeds 10 mΩ, so the upper limit was set at 5.5% by weight. In addition, when adding Mo and Nb in combination, 3% by weight
．． When INb+Mo<7, sufficient hardness cannot be obtained. On the other hand, 3. When INb+Mo>17, the contact electrical resistance is 10mΩ
exceed. Therefore, the weight percent of Mo and Nb is 7≦3.1
It needs to be in a range that satisfies the relational expression Nb+Mo≦17.
Ｆｅ
Ｆｅは置換型に固溶しＮｉの硬度を高めるが、その寄与
は非常に小さく硬化元素としては期待できない。しかし
Ｆｅを含む原料は含まない原料に比べ価格が格段安いた
め、本発明合金の製造コスト低減の面から、このＦｅ含
有原料の使用は重要である。Ｆｅは接触電気抵抗を高め
る元素であり、その程度はＮｂよりは小さいがＭｏより
は大きく、含有量が１０重量％を越えると接触電気抵抗
が１０ｍΩを越えるのでその許容可能な上限を１０重量
％とした。Fe Although Fe is solid dissolved in a substitutional type and increases the hardness of Ni, its contribution is very small and cannot be expected as a hardening element. However, since raw materials containing Fe are much cheaper than raw materials that do not contain Fe, the use of Fe-containing raw materials is important from the perspective of reducing the manufacturing cost of the alloy of the present invention. Fe is an element that increases contact electrical resistance, and its degree is smaller than Nb but larger than Mo. If the content exceeds 10% by weight, the contact electrical resistance exceeds 10mΩ, so the allowable upper limit is set at 10% by weight. And so.

Furthermore, in order to judge whether the alloy of the present invention could be produced, the quality of hot workability was indicated by the presence or absence of cracks after hot rolling.

This is what was plotted. In this figure, the straight line A-A' indicated by a dashed line is a boundary line with a contact electrical resistance of 10 mΩ, and the component range below this boundary line is a good range of contact electrical resistance. Also, due to hot workability constraints, Mo=8%
The straight line is shown as a broken line, and the area to the left of this line has good hot workability, and the area to the right has poor hot workability. Therefore, the region on the right side was excluded from the composition range of the alloy of the present invention.

This is the boundary line for v=140, and the thin solid line c-c' is the boundary line for Hv=140 when C<0.05%. Among these, the boundary line c-c in the case of Co0.05%
' is very close to the upper limit of the contact electrical resistance, and the range of MO and Nb, which have good hardness and contact electrical resistance, becomes extremely narrow, making it difficult to establish it as a practical alloy. On the other hand, when C≧0.05%, the shaded area shown in the figure is Hv≧140 and contact electrical resistance≦1.
This is a region that satisfies 0 mΩ and has good hot workability, and matches the composition range of the alloy of the present invention.
