- the present invention is used in the medical field and glasses frames, etc., where high strength and low rigidity are required, and is a titanium alloy presumed to be manufactured by a melting method which is a low-cost manufacturing method, and glasses formed from the alloy It relates to a frame and a golf club head. Background art
- Titanium alloy which is lighter and stronger than iron and has excellent corrosion resistance and biocompatibility, is widely used in medical fields such as artificial bones and artificial joints, and in accessories such as eyeglass frames and watches. Have been. In such applications, compatibility with the human body is the most important requirement, but since the problem of nickel allergy to the human body became apparent, when applying titanium alloys to these fields, More stringent evaluations are being made, and the required level of each characteristic is increasing. In particular, when used in such medical fields and applications such as jewelry, the issue of not only suitability for human tissue but also wearability is a major consideration, so it is easy to deform by applying external force. However, there is a strong demand for the development of materials that return to their original shape upon unloading, are less likely to be permanently deformed, and can be reduced in weight, that is, alloys with low rigidity and high strength. I got it.
- Patent Document 1 discloses a titanium containing 10 to 20% or 35 to 50% by weight of niobium and 20% or less of zirconium by weight. An alloy is disclosed (see Patent Document 1).
- Patent Document 2 discloses that a titanium alloy containing 30 to 60% by mass of a vanadium group element and one or more of the metal elements consisting of zirconium, hafnium and scandium are added to the alloy. 20 mass. An alloy containing less than / 0 or an alloy containing 0.08 to 0.6% by mass of oxygen in these titanium alloys is disclosed (see Patent Document 2).
- Titanium alloys are widely used in golf club heads because they have a lower specific gravity than iron, have excellent corrosion resistance, and have high specific strength. 15-3-3-3 alloy (15% V-3% A 1-3% Cr-3% Sn-76% Ti) 15-5-3 alloy (15% Mo-5% Zr-3% A1-77% Ti). Further, the invention disclosed that the alloy described in Patent Document 2 is applicable not only to decorative articles but also to golf clubs because the alloy has an excellent specific Young's modulus and is suitable for golf clubs (face portion and shaft). (See Patent Document 3).
- Patent Document 2 Japanese Patent Application Laid-Open No. 2001-247924
- Patent Document 3 Japanese Patent Application Laid-Open No. 2001-246029
- Patent Document 1 describes a low-rigidity titanium alloy that can be strengthened by aging treatment.
- the obtained tensile strength is 100% even after aging treatment. It is less than OMPa.
- high strength exceeding 100 OMPa can be secured by performing cold working.However, even when performing cold working, the strength is possible when aging treatment is performed. No strength exceeding 100 OMPa could be achieved without it.
- the aging treatment improves the strength, but also increases the Young's modulus. At the same time, there is a problem that the characteristic of low rigidity, which has been obtained, is lost. Further, the necessity of the aging treatment means that the number of steps increases, and there is a problem that the steps become complicated.
- Patent Literature 2 and Patent Literature 3 which describe Ti alloys for golf clubs show that some of the alloys of the invention have an alloy having a bow I tension elastic limit of 100 OMPa or more.
- the invention is described in this document, although it is not clearly stated in the claims, as is clear from the description of the examples, the invention is substantially based on the premise of manufacturing by sintering. Has become. Although many examples of alloys containing 30% or more of Nb are described in Examples of this document, the inventors and others have confirmed by experiments that such a large amount of Nb-containing alloys can be produced by the melting method. When manufactured, it was found that it was difficult to manufacture an ingot having uniform components, and it was difficult to manufacture a material having uniform properties such as strength by a melting method. When the method is limited to the sintering method, there is a problem that the cost is significantly higher than that of the production by the melting method, and it is difficult to reduce the cost.
- the present invention has a low Young's modulus, good cold workability, can easily achieve a high strength of 100 OMPa or more without relying on aging treatment, and has a high mounting when applied to accessories.
- One object is to make it possible to manufacture a spectacle frame that is lightweight and has improved wearability using the alloy.
- Another object is to provide a new titanium alloy that can obtain a large flight distance when applied to the face portion of a golf club head.
- the present inventors have conducted intensive research to find out a range of components that can obtain excellent characteristics in all of high strength, low rigidity, and cold workability, and that can be manufactured by a melting method. As a result, the following findings were obtained, and the present invention was completed.
- Titanium alloys generally have a Young's modulus of about 80 to 11 OGPa, but when Nb and V are added in appropriate amounts, stress-induced transformation occurs at low stress below the yield stress. As a result, a thermoelastic martensite is generated and an apparent strain is generated, and when stress is removed, the matrix returns to the original parent phase by reverse transformation, so that the Young's modulus can be reduced.
- Patent Document 2 the same applies to the invention of Patent Document 2 described above.
- a large amount of Nb can be added. By limiting the upper limit to 25%, it has been found that it is possible to produce by melting rather than sintering.
- thermoelastic martensite due to the effects of the addition of Mo and Zr described below, a high strength of at least 100 OMPa can be achieved by cold working alone without relying on aging treatment, and the formation of thermoelastic martensite can be achieved. It can be compatible with the obtained low rigidity.
- Non-Patent Document 1 Titanium Vol.50, No.3, P185 ⁇ : L92
- the alloys developed based on the concepts (1) and (2) above are extremely suitable for the characteristics required of this golf club, and have a limit to return to their original shape when unloaded even when deformed. It was found that the strain value was extremely high and high elastic energy could be stored.
- the present invention has been achieved by obtaining the findings of (1) to (3) above.
- the first invention completed based on the findings described above is one or two of mass%, Nb: 25% or less, V: 15% or less (however, Nb + V 0.5%, V when combined with Nb and V is less than 10%), Mo: 3 to 20%, Zr: 7.1 to 30 ° /. , O: 0.30% or less, the balance being Ti and unavoidable impurity elements, characterized in that it is a low-rigidity / high-strength titanium alloy excellent in cold workability.
- Nb 25% or less
- V 15% or less
- Nb and V are the most important elements for the present invention, and by adding one or two of Nb and V, as described above, a thermoelastic martensite is generated at the time of stress loading, and the original at the time of stress removal. By returning to the parent phase, a low Young's modulus can be achieved. To achieve this effect, at least the sum of Nb and V The prevalence must be at least 0.5%. In particular, since Nb has a large Young's modulus reduction effect, it is more preferable to add Nb alone if either one is selected. However, if it is added in a large amount, it is sufficient to manufacture by sintering.However, it is difficult to manufacture an ingot with uniform performance by the ingot manufacturing method, and stable performance cannot be obtained. 25% and V are 15%. When Nb and V are combined, the upper limit of V needs to be less than 10% for the same reason.
- Nb and V tends to increase as the amount of addition increases, and the weight reduction effect may be reduced. Therefore, when importance is placed on the specific gravity, it is desirable that the total content of Nb and V is less than 30%.
- Nb be in the range of 1 to 18% and V be limited to 5% or less. In this case, if Nb is less than 1% or more than 18%, or if V is more than 5%, it may be difficult to improve both solubility and cold workability. .

- Nb is set to the range of 2 to 6% when Mo is 8% or more, it is possible to further improve the solubility and the cold workability, in particular, the solubility.
- the Nb content is in the range of 12 to 16%, the cold workability among the solubility and the cold workability can be further improved.

Less than 10%), Mo: 3 to 20%, Zr: 7.1 to 30%, O: 0.30% or less, with the balance being Ti and unavoidable impurity elements In the glasses frame.
- the titanium alloy in the second invention corresponds to the titanium alloy in the first invention, and can achieve low rigidity and high strength only by cold working without relying on aging treatment, and It is a titanium alloy that can be manufactured at low cost because it can be manufactured by the melting method instead of the bonding method.
- the eyeglass frame is always worn by the person on the face and active, there is a strong demand for weight reduction, and since it is required to be fit with the face, it can be easily deformed by external force and immediately after the external force is removed. This is because it is necessary to return to the original shape, and it is the product that requires the highest rigidity and low rigidity.
