金の改良に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to rings, necklaces, brooches, tie pins,
This invention relates to the improvement of platinum alloys used as materials for cufflinks, watch frames, watch bands, lighters, writing utensils, eyeglasses, earrings, etc.
（従来技術とその問題点）
従来、上述の如き装飾品材料としては白金−パラジウム
（５〜１５重量％）系合金が多用されている。この合金
は、加工性、鋳造性に優れているが、機械的強さ特に硬
さが低い為、研摩中にすり傷、押傷が付き易く且つ光沢
が出にくくまた完成品として使用している場合も傷が付
き易くまた宝石付指輪の場合、宝石を止めている部分が
ゆるんで宝石が脱落すると言う欠点があった。(Prior art and its problems) Conventionally, platinum-palladium (5 to 15% by weight) alloys have been widely used as ornamental materials as described above. This alloy has excellent workability and castability, but because of its low mechanical strength and particularly low hardness, it is easily scratched and stamped during polishing, and is difficult to produce gloss, and is used as a finished product. Rings with jewels also have the disadvantage that the part that holds the jewel in place loosens and the jewel can fall off.
（発明の目的）
本発明は上記の欠点を解消せんが為になされたものであ
り、機械的強さ、加工性に優れた装飾用白金合金を堤供
せんとするもである。(Objective of the Invention) The present invention has been made in order to eliminate the above-mentioned drawbacks, and aims to provide a platinum alloy for decoration that has excellent mechanical strength and workability.
（発明の構成）
本発明による装飾用白金合金は、白金８４〜９６重量％
、ガリウム２〜１０ｆｆｉ量％、鉄０．５〜ｌＯ重■％
よりなる時効硬化特性を具備したものである。(Structure of the Invention) The decorative platinum alloy according to the present invention has a platinum content of 84 to 96% by weight.
, gallium 2-10ffi%, iron 0.5-10w%
This material has age hardening properties.
本発明による装飾用白金合金に於いて、ガリウムを添加
した理由は、Ｐｔ−Ｇａの２元状態図からも明らかなよ
うにＱａはｐｔに対して１３６１℃で最大固溶量６ｆｆ
Ｉｆｆｉ％を示し、その固溶限は温度下降と共に漸次減
少し、固溶体領域まで加熱し急冷する溶体化処理を行っ
た後、適当な温度で時効させると著しい時効硬化性を現
わす為である。その添加量が２重量％未満では、硬さの
改善が殆んどな（１０重量％を超えるとｐｔとＱａが金
属間化合物を作り、加工性が恋くなるからである。In the decorative platinum alloy according to the present invention, the reason for adding gallium is that, as is clear from the Pt-Ga binary phase diagram, Qa has a maximum solid solution amount of 6ff at 1361°C with respect to pt.
This is because the solid solubility limit gradually decreases as the temperature decreases, and if it is aged at an appropriate temperature after being subjected to solution treatment in which it is heated to a solid solution region and rapidly cooled, it exhibits remarkable age hardenability. If the amount added is less than 2% by weight, there will be little improvement in hardness (if it exceeds 10% by weight, pt and Qa will form an intermetallic compound, resulting in poor workability.
また鉄を添加した理由は、鉄は脱酸効果があり、ｖｆ造
時に酸素７；度を抑制でき、鋳造性を向上させ、また高
温（例えばろう行中）での結晶粒の粗大化を防止して機
械的強さの低下を防止する為であり、その添加量が０．
５重量％未満では硬さの改善が殆んどなく１０重量％を
超えると合金が硬くなりすぎ、加工性が悪くなるからで
ある。The reason for adding iron is that iron has a deoxidizing effect and can suppress oxygen levels during VF forming, improving castability and preventing coarsening of crystal grains at high temperatures (for example, during brazing). This is to prevent a decrease in mechanical strength, and the amount added is 0.
This is because if it is less than 5% by weight, there is almost no improvement in hardness, and if it exceeds 10% by weight, the alloy becomes too hard and the workability deteriorates.
