（産業上の利用分野）
本発明は、装飾用複合素材の改良に係り、特に
眼鏡フレーム、ネクタイピン、時計バンド等の装
飾品の素材として好適な装飾用Ti基複合素材に
関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to the improvement of decorative composite materials, and in particular to the improvement of decorative Ti-based composite materials suitable as materials for decorative items such as eyeglass frames, tie pins, and watch bands. It's about the material.
（従来技術とその問題点）
近時、各種装飾品に於いて、活動性を高める意
味や装着感を高める意味から、軽量且つばね特性
に優れた装飾用素材が要望されている。(Prior Art and its Problems) Recently, there has been a demand for decorative materials that are lightweight and have excellent spring characteristics for various decorative items in order to increase activity and comfort when worn.
このようなことから比重4.5のTi或いはTi基合
金の装飾品への応用が種々試みられている。 For this reason, various attempts have been made to apply Ti or Ti-based alloys with a specific gravity of 4.5 to decorative items.
然るに、Ti或いはTi基合金は非常に酸化し易
く、ろう付が困難であり、しかも非常に活性であ
る為ダイスなどと反応し、焼付が起り易く、塑性
加工の難しい材料である。また、Tiの表面は強
固な酸化膜で覆われているため、装飾用素材に不
可欠な表面処理、特にめつき処理が難しいという
欠点がある。この為、Ti或いはTi基合金単独で
の装飾用素材への適用は、特殊な分野に限られて
いる。 However, Ti or Ti-based alloys are very easily oxidized, difficult to braze, and are also very active, so they react with dies and are susceptible to seizure, making them difficult to plastically work. Additionally, since the surface of Ti is covered with a strong oxide film, it is difficult to perform surface treatments, especially plating treatments, which are essential for decorative materials. For this reason, the application of Ti or Ti-based alloys alone to decorative materials is limited to special fields.
Ti或いはTi基合金を一般的な装飾品に適用さ
せる為に、第３図に示す如くTi或いはTi基合金

採られているが、Ti或いはTi基合金の芯材１は、
上記外被金属２と脆弱な金属間化合物の層４を作
り易く、この層４から外被金属２と芯材１とが剥
離するという欠点があつた。 In order to apply Ti or Ti-based alloys to general decorative items, as shown in Figure 3, Ti or Ti-based alloys are used as the core material 1, and the outer surface is coated with conventionally used Karat gold, Pt alloys, Ag. A method has been adopted in which a Ti-based composite material 3 is formed by coating the outer sheath metal 2 of noble metal such as alloy, Ni-Cr alloy, Cu-Ni alloy, etc. However, the core material of Ti or Ti-based alloy 1 is
There was a drawback that a layer 4 of a brittle intermetallic compound was easily formed with the outer sheath metal 2, and the outer sheath metal 2 and the core material 1 were separated from this layer 4.
特に装飾用素材には、ろう付けによる接合が不
可欠であるが、例えば前記Ti基複合素材３を第
４図に示す如くプレス成形した板材５同志をろう
材６にてろう付すると、加熱によりさらに金属間
化合物層４が成長し、且つ連続する為に、一層剥
離し易くなるという欠点があつた。 Particularly for decorative materials, joining by brazing is indispensable. For example, when plate materials 5 made by press-forming the Ti-based composite material 3 as shown in FIG. Since the intermetallic compound layer 4 grows and is continuous, it has the disadvantage that it is more likely to peel off.
（発明の目的）
本発明は、斯かる欠点を解消すべくなされたも
のであり、軽量且つばね特性に優れ、外観が高級
装飾用素材の様相を呈し、さらに焼鈍、ろう付等

にくい装飾用Ti基複合素材を提供することを目
的とするものである。(Purpose of the Invention) The present invention has been made in order to eliminate such drawbacks, and is lightweight and has excellent spring characteristics, has an appearance similar to that of a high-grade decorative material, and has a structure that is easy to use during processing such as annealing and brazing. The object of the present invention is to provide a decorative Ti-based composite material that is difficult to peel off even when intermetallic compounds are formed.
（発明の構成）
本発明の装飾用Ti基複合素材は、Ti又はTi基
合金が体積比で50〜90％をなすTi基複合素材で
あつて、外表面が貴金属合金、Ni−Cr合金、Cu

合金が繊維状に分散されていることを特徴とする
ものである。(Structure of the Invention) The decorative Ti-based composite material of the present invention is a Ti-based composite material in which Ti or Ti-based alloy accounts for 50 to 90% by volume, and the outer surface is made of a noble metal alloy, a Ni-Cr alloy, Cu
- It is characterized by being covered with either a Ni alloy and having a core of Ti or a Ti-based alloy dispersed in the form of fibers.
このように本発明の装飾用Ti基複合素材は、
芯材であるTi又はTi基合金が繊維状に分散され
ているので、例えろう付の際に外被金属との間に
金属間化合物の層が生成されても不連続である
為、芯材と外被金属は剥離することが無い。 In this way, the decorative Ti-based composite material of the present invention
Since the core material Ti or Ti-based alloy is dispersed in the form of fibers, even if a layer of intermetallic compound is formed between the core material and the outer metal during brazing, it will be discontinuous. And the outer sheath metal will not peel off.
本発明の装飾用Ti基複合素材に於いて、Ti又
はTi基合金の体積比を50〜90％と限定した理由
は、50％未満では軽量、高ばね性化に十分ではな
く、90％を超えるとTi又はTi基合金が確実に繊
維状に分散せず、結果として金属間化合物の層の
連続する部分ができて、芯材と外被金属が剥離し
易くなるからである。 The reason for limiting the volume ratio of Ti or Ti-based alloy to 50 to 90% in the decorative Ti-based composite material of the present invention is that less than 50% is not sufficient to achieve lightweight and high spring properties; This is because if it exceeds the range, the Ti or Ti-based alloy will not be reliably dispersed in the form of fibers, and as a result, a continuous portion of the intermetallic compound layer will be formed, making it easy for the core material and the sheath metal to separate.

る。 The method for manufacturing the decorative Ti-based composite material of the present invention includes, for example, mixing a predetermined amount of fine grains of Ti or Ti-based alloy and powder of noble metal alloy, filling a capsule of noble metal alloy, etc., and then compressing the powder. There are methods of forming by sintering, extrusion, drawing, etc.

た。(Example) An example of the decorative Ti-based composite material of the present invention will be described by comparing it with a conventional example. First of all, conventional decoration
To explain the Ti-based composite material, as shown in FIG. 3, a Ti-based composite material 3 with a wire diameter of 3 mm, in which the core material 1 is pure Ti and the outer sheath metal 2 is Ni-Cr 10 wt%, was formed by extrusion and drawing. At this time, the volume ratio of Ti and Ni-Cr10wt% was set to 4:1. This wire was press-formed into a plate material with a thickness of 1.5 mm, and after brazing the plate materials 5 together with a brazing material 6 as shown in Fig. 4, a peel test of the plate material 5 was performed, and the average weight was 8 kg/ Peeling occurred from the joint surface between the core material 1 and the outer sheath metal 2 at a strength of mm 2 .

い。 Next, to explain the decorative Ti-based composite material of the example, Ti fine particles with a diameter of 2 mm and a length of 2 mm are mixed with Ni-Cr 10 wt% alloy powder with an average particle size of 10 μ, and this is made into Ni-Cr 10 wt% capsules. Filled, then compressed, sintered, extruded, and drawn to create a wire with a diameter of 3 mm.
Made of Ti-based composite material. At this time, Ti and Ni−Cr10wt
% by volume was 4:1. The cross section of this line is as shown in Figure 1a and b, where the Ti core material 1' is Ni-
It was dispersed in the form of fibers in the outer sheath metal 2' containing 10 wt% Cr. This wire 3' was press-formed to form a plate with a thickness of 1.5 mm, and after brazing the plates 5' together with a brazing filler metal 6 as shown in Fig. 2, a peel test of the plate 5' was performed. , peeling occurred from the brazing filler metal 6 at an average strength of 25 kg/mm 2 , but did not peel from the joint surface between the core material 1' and the outer sheath metal 2'. This is simply because the intermetallic compound layer 4' formed between the core material 1' and the outer sheath metal 2' is discontinuous.

優れた効果がある。(Effect of the invention) As can be seen from the above explanation, the decorative Ti-based composite material of the present invention has a volume ratio of 50 to 90% of Ti or Ti-based alloy.
%, it is lightweight and has high spring properties, and the core material, Ti or Ti-based alloy, is dispersed in the form of fibers and covered with an outer covering metal such as a precious metal alloy, so the appearance is similar to that of a high-grade decorative material. Moreover, even if an intermetallic compound is generated between the core material and the outer sheath metal during heat treatment such as annealing or brazing, it becomes discontinuous, so the core material and the outer sheath metal become discontinuous. It does not peel off and has excellent effects such as making it possible to create ornaments with complex shapes.
