Description
【発明の詳細な説明】 本発明はチタン−銅系の高力合金の改良に関する。[Detailed description of the invention] The present invention relates to improvements in titanium-copper based high strength alloys.
チタン−銅合金は高力銅合金として知られている。Titanium-copper alloys are known as high strength copper alloys.
しかし、このチタン−銅合金はＴｉを多量に含有するた
め熱間加工性が悪く、また冷間加工による硬化が大きい
ため中間焼鈍を多く必要とした。However, this titanium-copper alloy has poor hot workability because it contains a large amount of Ti, and also requires a lot of intermediate annealing because it is hardened by cold working.
本発明はこのチタン−銅合金の欠点を改良するため、硬
度、強度、バネ性など低下させずに製造の容易な合金を
得ようとするものである。In order to improve the drawbacks of this titanium-copper alloy, the present invention attempts to obtain an alloy that is easy to manufacture without reducing hardness, strength, springiness, etc.
本発明合金はチタン１〜５重量％と、クロム２重量％以
下ジルコニウム１重量係以下の範囲内でクロムとジルコ
ニウムとを０．１重量係以上と、残部銅からなることを
特徴とする。The alloy of the present invention is characterized by comprising 1 to 5% by weight of titanium, chromium and zirconium in a range of 2% by weight or less and 1% by weight of zirconium, and 0.1% by weight or more of chromium and zirconium, and the balance being copper.
すなわち、クロムとジルコニウムを複合で添加すること
によりチタンの含有量を相対的に低下させ、強度、バネ
性などの特性低下をさせずに加工性を改善することがで
きたのである。In other words, by adding chromium and zirconium in combination, it was possible to relatively reduce the titanium content and improve workability without deteriorating properties such as strength and springiness.
クロムとジルコニウムはあまり多く添加してもその割に
強度の向上がないので、加工性改善効果との兼ね合いか
ら上記値とする。Even if too much chromium and zirconium are added, the strength will not be improved accordingly, so the above values are set in consideration of the effect of improving workability.
強度、硬度、バネ性のバランスから好ましくは０．５〜
２％、最も好ましくは０．８〜１．５％である。Preferably from 0.5 to the balance of strength, hardness, and springiness.
2%, most preferably 0.8-1.5%.
導電性を考慮する場合はクロムとジルコニウムの比を２
／１〜３／１程度にするとよい。When considering conductivity, the ratio of chromium and zirconium is set to 2.
It is best to set it to about /1 to 3/1.
チタンはなるべく減少させる方がよいが、あまり少なく
すると、硬度、強度、バネ性等に悪影響を及ぼすので、
これらの兼ね合いから上記の値とする。It is better to reduce titanium as much as possible, but if it is reduced too much, it will have a negative effect on hardness, strength, springiness, etc.
Based on these considerations, the above values are set.
本発明合金は析出硬化型合金であるので溶体化処理−→
冷間加工→時効処理が施される。Since the alloy of the present invention is a precipitation hardening alloy, it is subjected to solution treatment -→
Cold working → aging treatment is applied.
溶体化処理は８５０〜９２０℃で行うことが好ましく、
冷間加工は８０％以下の加工率の範囲で行なうことが好
ましく、時効処理は３５０〜５００℃で１〜３時間時間
性なうことが好ましい。The solution treatment is preferably carried out at 850 to 920°C,
The cold working is preferably carried out at a working rate of 80% or less, and the aging treatment is preferably carried out at 350 to 500°C for 1 to 3 hours.
実験例
第１表に示す成分組成の合金を９００℃で溶体化処理し
たのち急冷して６０係の冷間加工を施し、これを４２５
℃にて２時間時効処理した。Experimental Example An alloy having the composition shown in Table 1 was solution-treated at 900°C, then rapidly cooled and cold-worked at 60°C.
Aging treatment was performed at ℃ for 2 hours.
得られた合金の硬さ引張強さ、伸び、バネ限界値及び加
工性を第２表に示す。Table 2 shows the hardness, tensile strength, elongation, spring limit value, and workability of the obtained alloy.
第１表及び第２表から、本発明合金の加工性がすぐれ、
かつ特性もすぐれていることが分る。From Tables 1 and 2, it is clear that the alloy of the present invention has excellent workability;
It can also be seen that the properties are excellent.
