［発明の技術分野］
本発明は、眼鏡フレーム材料等に好適する軽量
でかつ強度の大きい装飾性に優れた複合材料に関
する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a lightweight, strong, and highly decorative composite material suitable for eyeglass frame materials and the like.
［発明の技術的背景とその問題点］
従来より、金属性眼鏡フレーム等の装飾材料と
して、NiにAg、Crを添加した耐食性と装飾性の
良好なNi基合金等が使用されている。[Technical background of the invention and its problems] Ni-based alloys, which are made by adding Ag and Cr to Ni and have good corrosion resistance and decorative properties, have been used as decorative materials for metal eyeglass frames and the like.
しかしながら、この材料は比重が割合大きいと
いう難点があり、昨今の眼鏡フレームの軽量化と
いう要求に応えることができなかつた。このため
軽いTi基金属を使用し、これにNi基金属を圧着
してクラツドさせたり、あるいはNi基合金をTi
基金属にめつきしたりして軽量化を図ることが行
われている。 However, this material has the disadvantage of relatively high specific gravity, and has not been able to meet the recent demand for lighter eyeglass frames. For this reason, a light Ti-based metal is used and a Ni-based metal is crimped onto it to form a cladding, or a Ni-based alloy is clad with a Ti-based metal.
Attempts are being made to reduce weight by plating the base metal.
しかしながら、クラツドによる方法はTi基金
属が脆い金属間化合物を形成するため、両者を圧
着させても両者間の密着性が悪くなり機械的強度
が劣るという欠点があり、まためつきによる方法
はTi基金属へのめつき性が悪く、さらにめつき
層は一般にポーラスであるため、耐食性に劣り、
しかもはがれやすいという欠点があつた。 However, the method using cladding has the drawback that the Ti-based metal forms a brittle intermetallic compound, so even if the two are crimped, the adhesion between them is poor and the mechanical strength is poor. It has poor plating properties to base metals, and since the plating layer is generally porous, it has poor corrosion resistance.
Moreover, it had the disadvantage of being easy to peel off.
本発明者らは、このような従来の欠点を解消す
るため鋭意研究を進めた結果、Ti基金属芯材の
上にAg等からなる中間層を介してNi基金属層を
被覆した積層材を使用した場合にTi基金属とNi
基金属との密着性に優れたクラツド材料が得られ
ることを見出した。 As a result of intensive research in order to eliminate these conventional drawbacks, the present inventors have developed a laminated material in which a Ni-based metal layer is coated on a Ti-based metal core material with an intermediate layer made of Ag etc. When used with Ti-based metals and Ni
It has been found that a clad material with excellent adhesion to the base metal can be obtained.
［発明の目的］
本発明は、このような知見に基づいてなされた
ものであり、軽量で強度の向上したTi基金属に
Ni基金属にクラツドさせた密着性に優れた複合
材料を提供しようとするものである。[Object of the invention] The present invention was made based on the above findings, and is an attempt to create a Ti-based metal that is lightweight and has improved strength.
The aim is to provide a composite material clad with Ni-based metal that has excellent adhesion.
［発明の概要］
すなわち本発明の複合材料はTi基金属芯材の
上に10μｍ以上100μｍ以下のAgおよび／または

It is characterized by being formed by cold working or warm working a laminated material formed by overlapping and covering Ni-based metal with an intermediate layer made of Cr interposed therebetween.

In addition to Ti, Al, V, Mn, Fe, Cu, Mo, Cr,
An alloy containing one or more elements such as W can be used. Note that when an alloy is used for the Ti-based metal core material, the Ti content in the alloy is preferably 90% or more. If it is less than 99%, plastic workability decreases, and the specific gravity due to added elements increases, reducing the weight reduction effect.
またNi基金属としては、純NiのほかにNiに

An alloy containing one or more elements such as Al, Mo, Sn, and Co can be used. Among them, it contains 13-15% Cr and 0.7-1.5% Ag.
Ni-based metals are preferable because they have excellent corrosion resistance and decorative properties. When using a Ni-based alloy as the Ni-based metal, the Ni content in the alloy should be 80
% or more.
本発明における中間層はAg、Crまたはこれら
の複合層で形成することにより、Ti基金属芯材
とNi基金属との密着性が良好となる。 By forming the intermediate layer in the present invention from Ag, Cr, or a composite layer thereof, the adhesion between the Ti-based metal core material and the Ni-based metal can be improved.
この中間層の被覆厚は10μｍ以上100μｍ以下が
好ましい。この中間層の厚さがあまり薄いに接合
強度の改善効果が少なく、逆にあまり厚いと接合
強度の改善効果は良好であるもの、コストが高く
なり工業上不利となるため、上記範囲とした。 The coating thickness of this intermediate layer is preferably 10 μm or more and 100 μm or less. If the thickness of this intermediate layer is too thin, the effect of improving the bonding strength will be small.On the other hand, if the thickness of the intermediate layer is too thin, the effect of improving the bonding strength will be good, but the cost will increase and this will be industrially disadvantageous, so the thickness is set in the above range.
また本発明において、熱間加工を採用せず冷間
加工あるいは温間加工を採用した理由は、熱間加
工を採用すると、脆い金属間化合物を形成しその
金属間化合物の発達が活発となり接合強度が小さ
くなるためである。 In addition, in the present invention, the reason why cold working or warm working is adopted instead of hot working is that when hot working is adopted, brittle intermetallic compounds are formed, and the development of the intermetallic compounds becomes active, which strengthens the bond. This is because it becomes smaller.
本発明における複合材料は、例えば下記の製造
方法により得ることが可能となる。 The composite material in the present invention can be obtained, for example, by the following manufacturing method.
例えば棒（線）状の複合材料を得る場合は、ま

上記パイプの内径にほぼ等しい径を持つTi基金
属棒を挿入することにより積層材を得る。ここで
Ni基金属パイプの太さおよび肉厚は軽量化のた
めにはTi基金属の比率を多くしたほうが好まし
いことを考慮して定める。 For example, when obtaining a rod (wire)-shaped composite material, first insert an ERW tube or a seamless pipe made of Ni-based metal into a material that has a diameter approximately equal to the inner diameter of the pipe covered with the material forming the intermediate layer. A laminate is obtained by inserting a Ti-based metal rod. here
The thickness and wall thickness of the Ni-based metal pipe are determined taking into account that it is preferable to increase the proportion of Ti-based metal in order to reduce weight.
次に得られた積層材を、冷間加工あるいは温間
加工を施して本発明の複合材料を得ることが可能
となる。 Next, the composite material of the present invention can be obtained by subjecting the obtained laminate to cold working or warm working.

Ti基金属の酸化あるいは窒化を防止することが
可能となる。ここで減面率を35％以上に限定した
のは、Ni基金属とTi基金属との密着性を向上さ
せるためである。この値未満では密着性が不十分
となる。 As for cold working, the laminated material is first drawn through a wire drawing die so that the area reduction rate in the first working is 35% or more. Here, the area reduction rate represents the reduction rate of the cross-sectional area of the workpiece before and after processing. Before this wire drawing process, the edges of the composite material are swaged, that is, rolled by rotating a die around the axis of the workpiece and rolling while forging. It is preferable to keep them in close contact with each other.
In addition, in this case, by providing a plug made of Ni-based metal at the end of the Ni-based metal pipe, the core material can be heated when air or nitrogen atmosphere is used as the heating atmosphere during annealing in post-processing. is
It becomes possible to prevent oxidation or nitridation of Ti-based metals. The reason why the area reduction rate is limited to 35% or more is to improve the adhesion between the Ni-based metal and the Ti-based metal. Below this value, adhesion will be insufficient.
続いて、必要であれば減面率が45〜60％となる
ように再度線引き加工を行う。すなわち、パイプ
がシームレスパイプであれば一度の加工で減面率
50〜60％のものを得ることが可能であるが、電継
管は複数回の加工で減面率60％まで加工すること
が必要である。なお減面率が60％を越えると加工
が困難となる。 Then, if necessary, wire drawing is performed again so that the area reduction rate is 45 to 60%. In other words, if the pipe is a seamless pipe, the area reduction can be achieved with one processing.
Although it is possible to obtain an area reduction of 50 to 60%, it is necessary to process the electrical connecting pipe multiple times to reach an area reduction of 60%. Note that if the area reduction rate exceeds 60%, processing becomes difficult.
次いで熱処理して焼鈍を施す。熱処理温度は
550〜750℃が適しており、この温度より低いと

熱処理温度により適宜設定する。 Then, it is heat treated and annealed. The heat treatment temperature is
550~750℃ is suitable, lower than this temperature
If the Ni-based metal is not annealed and above this temperature, the Ni
Intermetallic compounds between Ti-based metals and Ti-based metals are formed significantly, resulting in brittleness. Further, the heat treatment time is appropriately set depending on the size of the material and the heat treatment temperature.
次に、必要に応じて250〜450℃、好ましくは
300〜400℃の温間加工を施して所定の形状に成形

向上、強加工の容易さという利点がある。250℃

It is warm-processed at 300-400°C and molded into a predetermined shape. Warm processing has the advantage of improved adhesion and ease of strong processing. 250℃
If it is less than that, cracks may occur when subjected to heavy processing. Also, cracks may occur even if processed at temperatures exceeding 450℃.
以上の冷間加工によれば、次に述べる温間加工
によるよりも長尺の複合材料が得られる。 According to the above cold working, a longer composite material can be obtained than by the warm working described below.
また温間加工としては、積層材を200〜500℃で
温間押出しする。押出し圧力は500〜13000Kg／cm2
程度であり静水圧押出機を用いて行うのが好まし
い。押出し温度が200℃未満ではNi−Ti間の金属
拡散接合が不十分となり、500℃を越えると脆く
なる。次いで550〜750℃の温度で熱処理して軟化
焼鈍する。 As for warm processing, the laminated material is warm extruded at 200 to 500°C. Extrusion pressure is 500~13000Kg/ cm2
It is preferable to use a hydrostatic extruder. If the extrusion temperature is less than 200°C, the metal diffusion bonding between Ni and Ti will be insufficient, and if it exceeds 500°C, it will become brittle. Then, it is heat treated at a temperature of 550 to 750°C to soften and anneal.
上記製造方法においては棒（線）状の複合材料
を得る場合について説明したが、本発明において
は棒（線）状に限らず板状の複合材料などに対し

In the case of partial processing, it is possible to obtain a composite material by performing rolling processing. Then, the desired composite material is obtained by annealing and molding. In addition, in order to prevent oxidation or nitridation of the Ti-based metal core material, the heating atmosphere during annealing to obtain this plate-shaped composite material is
A vacuum or argon (Ar) gas atmosphere is preferred.
