Description

この発明は、ゴルフクラブヘッド用合金に関し、特に、軽量の上、成形が容易で、且つ耐磨耗性も制振能も高いゴルフクラブヘッド用合金に関する。   The present invention relates to a golf club head alloy, and more particularly to a golf club head alloy that is lightweight, easy to mold, and has high wear resistance and vibration damping capability.

従来のゴルフクラブヘッド用合金は、様様あるが、チタンのマトリックスで、アルミニウム、モリブデン、バナジウムなどを含んだもの、例えば(6Al-4V Ti)合金及び(6Al-1Mo-1V-2Zr Ti)合金などが、軽量の上、耐磨耗性も制振能も高いので、よく使われている。   There are various conventional golf club head alloys, but a titanium matrix containing aluminum, molybdenum, vanadium, etc., such as (6Al-4V Ti) alloy and (6Al-1Mo-1V-2Zr Ti) alloy. However, it is often used because of its light weight, high wear resistance, and high damping performance.

しかし、このようなチタンマトリックス合金は、ゴルフクラブヘッド用のものとして、まだまだ理想だとは言えない。例えば、軽量の点ついて、一般のゴルファーは、100gくらい下げられればいいなぁーと手にあるゴルフクラブを撫でながらアンケートに回答し、手に答える振動について、もっと小さければと、そして、クラブヘッド先の摩耗された傷を見ながら、耐磨耗性がもっと高ければと惜しんで言うことも普段見られる。なお、使用者ばかりでなく、生産者の方からも、時々、もっと成形しやすければと聞いたことがある。   However, such a titanium matrix alloy is still not ideal as a golf club head. For example, about a lightweight point, a general golfer should be able to lower it by about 100g, answer a questionnaire while stroking a golf club in his hand, if the vibration to answer the hand is smaller, and the club head ahead It's common to see the worn-out scratches as if they are more wear-resistant. I have heard from producers as well as users that it is sometimes easier to mold.

前記に鑑みて、本発明は、もっと軽量の上、成形がより容易で、且つ耐磨耗性も制振能も従来より高いゴルフクラブヘッド用合金を提供しようとすることをその目的とする。   In view of the foregoing, it is an object of the present invention to provide an alloy for a golf club head that is lighter, easier to mold, and has higher wear resistance and vibration damping capability than before.

前記目的を達成するために、本発明は、アルミニウム7.8〜10.0重量%、モリブデン2.0重量%未満、バナジウム2.0重量%未満、珪素2.0重量%未満、及び残部としてのチタンを含んだゴルフクラブヘッド用合金を提供する。   In order to achieve the above object, the present invention provides 7.8-10.0% by weight of aluminum, less than 2.0% by weight of molybdenum, less than 2.0% by weight of vanadium, less than 2.0% by weight of silicon, and the balance. An alloy for a golf club head containing titanium is provided.

前記組成による合金は、発明者の試験製作によると、比重が0.25位下がるので、従来より100g下がるゴルフクラブヘッドを製造することができる。これは、組成におけるアルミニウムの増加によるのだと思われる。   According to the inventor's test production, the alloy having the above composition has a specific gravity lowered by about 0.25, so that it is possible to manufacture a golf club head that is reduced by 100 g from the conventional one. This is likely due to the increase in aluminum in the composition.

前記組成による合金は、発明者の試験製作によると、伸び率が0.5〜2%上がるので、従来より制振能の良い、即ち安定性が高いゴルフクラブヘッドを製造することができる。これは組成の比例によるのだと思われる。例えばアルミニウムの増加は、合金結晶をもっと細かくさせる効果があり、特にモリブデン及びバナジウムをそれぞれ従来の1.0重量%((6Al-1Mo-1V-2Zr Ti)合金の場合、アルミニウム6.0重量%、モリブデン1.0重量%、バナジウム1.0重量% 、ジルコニウム2.0重量%)から1.8重量%か2.0重量%未満に上げた場合、その効果がもっと良い。   According to the inventor's test production, the alloy having the above composition increases in elongation by 0.5 to 2%, so that it is possible to manufacture a golf club head having better vibration damping capability, that is, higher stability than the conventional one. This seems to be due to the proportion of the composition. For example, an increase in aluminum has an effect of making the alloy crystal finer, and in particular, molybdenum and vanadium are each 6.0% by weight of aluminum in the case of a conventional 1.0% by weight ((6Al-1Mo-1V-2Zr Ti) alloy). , Molybdenum 1.0 wt%, vanadium 1.0 wt%, zirconium 2.0 wt%) to 1.8 wt% or less than 2.0 wt%, the effect is better.

前記組成による合金は、発明者の試験製作によると、降伏強さが2〜10%上がるので、従来より耐摩耗性の良いゴルフクラブヘッドを製造することができる。これも組成の比例によるのだと思われる。これも、アルミニウムやモリブデン、バナジウムの増加による合金結晶の微細化が原因であろう。   According to the inventor's test production, the alloy having the above composition has a yield strength that is increased by 2 to 10%. Therefore, a golf club head with better wear resistance than before can be manufactured. This is also due to the proportion of the composition. This is also due to the refinement of alloy crystals due to the increase in aluminum, molybdenum and vanadium.

また、前記組成による合金は、珪素を含んでいるので、溶融状態での流動性が良く、ゴルフクラブヘッドへの鋳造成形性が従来より遥かに良い。前記組成による合金は、結晶が従来より細かいので、それを用いて鋳造成形したゴルフクラブヘッドの表面が緻密で、打球時の施力が打球面の微細なでこぼこによって分散されることなく、ボールを従来より方向正しく飛ばすことができる。   Further, since the alloy having the above composition contains silicon, the fluidity in the molten state is good, and the castability to the golf club head is much better than before. The alloy having the above composition is finer than the conventional crystal, so that the surface of the golf club head cast and molded using it is dense, and the applied force at the time of hitting the ball is not dispersed by the fine irregularities of the hitting surface. It can fly in the correct direction than before.

以下、実施例により、従来例と対比しながらこの発明を更に説明する。
この実施例における本発明のゴルフクラブヘッド用合金は、アルミニウム8.0重量%、モリブデン1.0重量%、バナジウム1.0重量%、珪素1.0重量%を含んだチタンマトリックス合金である。
この合金の製造方法は、従来の方法と同様であるので、ここでそれらを省く。
Hereinafter, the present invention will be further described by way of examples in comparison with conventional examples.
The golf club head alloy of the present invention in this example is a titanium matrix alloy containing 8.0 wt% aluminum, 1.0 wt% molybdenum, 1.0 wt% vanadium, and 1.0 wt% silicon.
Since the manufacturing method of this alloy is the same as the conventional method, they are omitted here.

表1は、この合金から試料を取って測定した機械性質を(6Al-4V Ti)合金及び(6Al-1Mo-1V-2Zr Ti)の機械性質と羅列してなるものである。   Table 1 shows the mechanical properties measured by taking a sample from this alloy and the mechanical properties of (6Al-4V Ti) alloy and (6Al-1Mo-1V-2Zr Ti).

この表1から分かるように、本発明の合金は、伸び率が(6Al-1Mo-1V-2Zr Ti)合金に対し0.5%、(6Al-4V Ti)合金に対し2%上がるので、従来より制振能の良い、即ち安定性が高いゴルフクラブヘッドが作れる。   As can be seen from Table 1, the elongation of the alloy of the present invention is 0.5% higher than that of the (6Al-1Mo-1V-2Zr Ti) alloy and 2% higher than that of the (6Al-4V Ti) alloy. A golf club head having better vibration damping capability, that is, higher stability can be produced.

本発明の合金は、降伏強さが(6Al-1Mo-1V-2Zr Ti)合金に対し2%、(6Al-4V Ti)合金に対し10%上がるので、従来より耐摩耗性の良いゴルフクラブヘッドが作れる。   The alloy of the present invention has a yield strength that is 2% higher than that of the (6Al-1Mo-1V-2Zr Ti) alloy and 10% higher than that of the (6Al-4V Ti) alloy. Can be made.

本発明の合金は、抗張強度が(6Al-1Mo-1V-2Zr Ti)合金に対しても、(6Al-4V Ti)合金に対しても7.5%位上がるので、従来より強度の良いゴルフクラブヘッドが作れる。   The tensile strength of the alloy of the present invention is about 7.5% higher than that of the (6Al-1Mo-1V-2Zr Ti) alloy and the (6Al-4V Ti) alloy. Golf club head can be made.

本発明の合金は、密度が(6Al-1Mo-1V-2Zr Ti)合金に対し0.25g/cm、(6Al-4V Ti)合金に対し0.31g/cm下がるので、従来より重量の80g〜120g位下がり、且つ結晶が従来より細かくて表面が緻密であるゴルフクラブヘッドが作れる。こういうゴルフクラブヘッドを使用すると、打球時の施力が打球面の微細なでこぼこによって分散されることなく、ボールを従来より方向正しく飛ばすことができる。 The alloys of the present invention has a density (6Al-1Mo-1V-2Zr Ti) alloy to 0.25 g / cm 3, since the relative (6Al-4V Ti) alloy 0.31 g / cm 3 down, than the weight of conventional A golf club head that is lowered by about 80 to 120 g, has a finer crystal than the conventional one, and has a fine surface can be produced. When such a golf club head is used, the ball can be blown in the correct direction as compared with the conventional one without the applied force at the time of hitting being dispersed by the fine bumps of the hitting surface.

また、本発明の合金は、珪素を含んでいるので、溶融状態での流動性が良く、ゴルフクラブヘッドへの鋳造成形性が従来より遥かに良い。   In addition, since the alloy of the present invention contains silicon, the fluidity in the molten state is good, and the castability to the golf club head is much better than before.

なお、本発明のゴルフクラブヘッド用合金は、種々のゴルフクラブヘッド及びヘッド本体における各部分、例えばウッドやアイアンにおけるクラウン部、ソール部、フェース部、及びサイド部等にも利用される。   The alloy for golf club heads of the present invention is also used for various parts in various golf club heads and head bodies, such as crown parts, sole parts, face parts, side parts, etc. in woods and irons.

以上説明した実施形態は、あくまでも本発明の技術的内容を明らかにする意図のものにおいてなされたものであり、本発明はそうした具体例に限定して狭義に解釈されるものではなく、本発明の精神とクレームに述べられた範囲でいろいろと変更して実施できるものである。   The embodiments described above are merely intended to clarify the technical contents of the present invention, and the present invention is not limited to such specific examples and is not interpreted in a narrow sense. Various modifications can be made within the scope described in the spirit and claims.

叙上のように、本発明によるゴルフクラブヘッド用合金は、比重が下がり、機械強さが上がる上、成形加工性も良いので、従来より軽量の上、耐磨耗性も制振能ももっと高い上、製造コストを大いに下げることができる。使用者も、生産者の方も、満足することができる。   As mentioned above, the golf club head alloy according to the present invention has a lower specific gravity, higher mechanical strength, and better moldability, so it is lighter than conventional and has more wear resistance and damping performance. In addition, the manufacturing cost can be greatly reduced. Both users and producers can be satisfied.
