【産業上の利用分野】本発明はゴルフクラブの改良に関

易で飛距離の出るクラブに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved golf club, and more particularly to a club having high durability, easy control of the direction of a hit ball, and long flight distance.

Description of the Related Art The face portion of a golf club that hits the ball must have high strength and wear resistance, and preferably has corrosion resistance so that it can withstand the harsh conditions of hitting and can be used for a long time. In order to make the head swing faster, it is better to be lightweight.

スに使おうとすると、砂などによる摩耗が問題になる。From such a point, it has been attempted to use an Al alloy until now, but it has not been put to practical use because of insufficient strength. From the viewpoint of wear resistance and corrosion resistance, it has been attempted to use ceramics as an insert material for the driver face, but it is not popular because it lacks toughness. What is in practical use is a driver face made by molding carbon fiber with synthetic resin. If you try to use this on the face of an iron, the problem of abrasion due to sand becomes a problem.

ヘッドは、ゴルフクラブのフェースの部分の材料として

使用し、本体の部分を別の材料で構成したものである。The head of the golf club of the present invention uses a Ti-Al alloy containing intermetallic compound TiAl as a main component as the material of the face portion of the golf club, and the main body portion of the head is different. It is composed of materials.

ある。As a specific example, FIG. 1 shows an example in which a head body (2A) made of Persimmon wood is combined with a face (1) made of a Ti--Al alloy. In the figure,
(3) is a sole made of Al alloy, and (4) is a screw for fixing. FIG. 2 shows an example in which a Ti-Al alloy face (1) is attached to a metal wood head body (2B) manufactured by casting a Ti alloy. In this figure,
(5) is a brazing layer for brazing. FIG. 3 shows an example of an iron, in which a face (1) made of a Ti—Al alloy is joined to a head (2C) made of stainless steel by press fitting.

ある。The Ti-Al alloy has an Al content of 30 to 3 by weight.
It accounts for 6% and the balance is selected from the composition range of Ti. In this range, Ti is slightly larger than Al in terms of atomic ratio, and an alloy having a structure in which Ti 3 Al is mixed with Ti 3 Al as a main component is formed. This is preferable because it has high toughness.

Various methods can be employed, such as brazing (FIG. 2), friction welding, resistance welding, press fit (FIG. 3), or gluing.
Among these methods, particularly in the case of brazing, friction welding, and resistance welding, if necessary, an intermediate material such as Ni foil may be placed on the joining surface to perform the joining to ensure the joining.

However, the inventor and his collaborators were suitable for the levitation melting-suction casting method. As a result, the production of the face used in the golf club of the present invention is facilitated.

Table 1 summarizes the results obtained by adding evaluations to the extent to which each material can satisfy the wear resistance and the corrosion resistance required as wood or iron.

The specific gravity is an appropriate value, and the type and thickness of the material forming the head portion can be relatively freely selected.

益が得られる。The golf club head of the present invention has a T material mainly containing an intermetallic compound TiAl as a face material.
By using the hardness of the iAl alloy, the high wear resistance and corrosion resistance that were not found in other metal materials and carbon fiber reinforced synthetic resins that have been used conventionally have been realized by utilizing the hardness of the material. On the other hand, the Ti-Al alloy has toughness that could not be expected in the face made of a ceramic material, can withstand an excessive impact, and can obtain the benefits of stability in the direction of a hit ball and increase in flight distance.
