に汎用されるにつれて、上記外観がブームになった。BACKGROUND OF THE INVENTION Among the common materials (eg gold or steel), titanium has always been a very important position for the manufacture of watch cases (body) for several years. Titanium has the advantage that it is significantly less expensive than gold, adapts very well to the skin and does not cause nickel allergy. In addition, its frosted appearance, which is readily perceived, has facilitated its commercial success, and has become a boom as the material has become widely used in watches or other mass-produced items.

いう危険性を生ずる。DISCLOSURE OF THE INVENTION The present invention first confirms that this very particular surface appearance of titanium commonly used in watches and clocks probably does not necessarily promote this boom. Thus, there is the danger that the beauty of this material will not always be accepted by the majority of customers.
【０００４】 先行技術において、既に、例えば、着色によってまたは他の材料に特殊なチタ

されている。しかしながら、張付け工程により部材のコストが増し、更に、衝撃
および深いスリ傷に対する部材の脆さが増す。In the prior art, attempts have already been made to improve the appearance of titanium watches, for example by coloring or by applying special titanium alloys to other materials. However, the sticking process increases the cost of the component and further increases the brittleness of the component against impact and deep scratches.
【０００５】 従って、本発明の課題は、先行技術のチタン製部材とは異なる外観を有し、他
の商業的新分野を占める可能性のあるチタン製時計部材を提案することにある。[0005] Accordingly, it is an object of the present invention to propose a titanium timepiece which has a different appearance than prior art titanium parts and may occupy other new commercial fields.
【０００６】 この課題は、本発明にもとづき、時計製造業において未知のチタン合金から作
製した時計類部材によって解決される。This problem is solved by a timepiece member made from a titanium alloy unknown in the timepiece manufacturing industry according to the present invention.

These special alloys have the advantage that they can be polished over large surfaces.

のが困難である。[0008] In the prior art, studies on the polishing of a titanium timepiece have already been conducted. However, in the case of the conventionally used titanium alloy, it is impossible to completely polish a large member (for example, a case body or a band). The resulting surface condition resembles orange skin and is therefore smaller (eg, bezel).
nette) or only a small part of the large part) is made of polished titanium. The appearance of orange skin is especially due to the presence of multiple alloys in the structure of two phases (eg, α and β phases) that vary in hardness and are therefore difficult to provide the same polished appearance. I do. European Patent Publication EP 416929 discloses a titanium alloy timepiece in which a worked member is heated to a temperature higher than the β transition temperature, that is, higher than about 780 ° C., and then rapidly cooled to shift to a martensitic phase. A method of manufacturing the case is described. Then, an age hardening operation is required before the watch case is polished. Therefore, this method, involving multiple operations, is difficult to perform on an industrial scale.

Of particles. Therefore, differences in polishing between adjacent particles are clearly seen. Therefore, an optimum polishing quality can be achieved by refining the microstructure of the alloy, that is, by reducing the particle size of the particles constituting the alloy of the timepiece. According to the invention, this refinement is achieved by subjecting the timepiece to thermomechanical treatment.

に加工し難い合金を使用するという動機をもたらさない。However, watchmakers are strongly biased by the inability to properly process and press the above materials, and the use of the above alloys in watchmaking is not considered in the prior art at all. For this reason, watchmaking always uses titanium alloys with low mechanical strength. The mechanical properties of this alloy are sufficient for watchmaking applications and do not provide the incentive to use alloys that are much more difficult to process.

Surprising results have been obtained, indicating that watch parts can be produced from the alloys, for example, using cutting tools such as those used for the processing of stainless steel and modern press tools.
Furthermore, acid etching is also possible. Thus, the above experiments show that a person skilled in the field of processing watch components can work on the new alloy with conventional tools, based on certain operations, without any prejudice. The new alloys described above can be processed, for example, by carefully selecting a processing tool from existing tools and reducing the processing speed.

Such polishing is not commonly used on titanium parts in watchmaking. Thus, the advantageous properties of the above materials (especially antiallergic properties) can also be used for watches of the type for which it is preferable to use other metals for aesthetic reasons.

(° C.). The thermomechanical treatment preferably comprises pressing of the member heated to a temperature in the range of 600 to 750C, more preferably to a temperature of 600 to 700C. Experiments have shown that heating at a temperature slightly below the β-transition temperature while applying a large pressure or deformation can achieve an effective refinement of the alloy microstructure. For refining the microstructure, various mechanisms (eg, dynamic recrystallization) can be used. By properly selecting the heating temperature and the applied deformation pressure, a particle size on the order of 1 μm smaller than 5 μm can be obtained.
