為讓本發明之上述及其他目的、特徵及優點能更明顯易懂，下文特舉本發明之較佳實施例，並配合所附圖式作詳細說明；此外，在不同圖式中標示相同符號者視為相同，會省略其說明。 In order to make the above-mentioned and other objects, features and advantages of the present invention more obvious and understandable, the preferred embodiments of the present invention are specifically cited below, and are described in detail in conjunction with the accompanying drawings; in addition, the same symbols are marked in different drawings are considered the same, and their descriptions will be omitted.
本發明高爾夫球桿頭合金的一較佳實施例，係包含鋁(Al)、鉬(Mo)、釩(V)、及選自包含鉻(Cr)、矽(Si)、鐵(Fe)、硼(B)及錫(Si)中的至少一個、以及平衡量的鈦(Ti)。如此，該高爾夫球桿頭合金可以形成一鈦合金，該高爾夫球桿頭合金可成型為高爾夫球桿頭之一桿頭本體或一打擊面板，本發明不予限制。 A preferred embodiment of the golf club head alloy of the present invention comprises aluminum (Al), molybdenum (Mo), vanadium (V), and is selected from the group consisting of chromium (Cr), silicon (Si), iron (Fe), At least one of boron (B) and tin (Si), and a balance of titanium (Ti). In this way, the golf club head alloy can be formed into a titanium alloy, and the golf club head alloy can be formed into a head body of a golf club head or a striking faceplate, which is not limited by the present invention.
具體而言，該高爾夫球桿頭合金係包含5.5~8重量份之鋁、1.7~3.3重量份之鉬、1.7~2.3重量份之釩、及選自包含小於或等於2重量份且不為0之鉻、小於或等於0.35重量份且不為0之矽、0.15~1.3重量份之鐵、0.05~0.2重量份之硼及2.5~3.5重量份之錫中的至少一個，以及平衡量的鈦。其中，鉻、矽、鉬及釩可以使該高爾夫球桿頭合金所形成之桿頭具有預定的強度。且鉬及釩可以提供該高爾夫球桿頭合金較佳的塑變性，以利進行加工作業。此外，在另一實施例中，該高爾夫球桿頭合金係可以包含7~8重量份之鋁、1.7~2.3重量份之鉬、1.7~2.3重量份之釩、1.4~2重量份之鉻、0.25~0.35重量份之矽、0.7~1.3重量份之鐵以及平衡量的鈦。 Specifically, the golf club head alloy system includes 5.5-8 parts by weight of aluminum, 1.7-3.3 parts by weight of molybdenum, 1.7-2.3 parts by weight of vanadium, and is selected from the group consisting of less than or equal to 2 parts by weight and not 0. At least one of chromium, less than or equal to 0.35 parts by weight and not 0 of silicon, 0.15-1.3 parts by weight of iron, 0.05-0.2 parts by weight of boron and 2.5-3.5 parts by weight of tin, and a balance of titanium. Among them, chromium, silicon, molybdenum and vanadium can make the club head formed by the golf club head alloy have predetermined strength. Moreover, molybdenum and vanadium can provide better plasticity of the golf club head alloy to facilitate processing operations. In addition, in another embodiment, the golf club head alloy system may include 7-8 parts by weight of aluminum, 1.7-2.3 parts of molybdenum, 1.7-2.3 parts of vanadium, 1.4-2 parts of chromium, 0.25-0.35 parts by weight of silicon, 0.7-1.3 parts by weight of iron and a balance of titanium.
進一步來說，鋁金屬可以穩定鈦合金的α相，可以提升高爾夫球桿頭合金製成桿頭的成型率。然而，過高的鋁會導致桿頭的脆化，過低的鋁又會使得成型率不佳。因此，在另一實施例中，高爾夫球桿頭合金可以包 含7.5重量份之鋁，使得高爾夫球桿頭合金製成桿頭時，具有較佳的成型率以及較佳的強度。 Furthermore, the aluminum metal can stabilize the α-phase of the titanium alloy, which can improve the forming rate of the club head made of the golf club head alloy. However, too high aluminum will lead to embrittlement of the club head, and too low aluminum will make the molding rate poor. Thus, in another example, the golf club head alloy may include Containing 7.5 parts by weight of aluminum, the golf club head alloy has better molding rate and better strength when the club head is made of it.
鉬金屬可穩定鈦合金的β相，該高爾夫球桿頭合金中添加鉬可提升該高爾夫球桿頭合金所製成之桿頭的抗拉強度，使該桿頭不易在擊球後發生凹陷。此外，在另一實施例中，高爾夫球桿頭合金可以包含2重量份之鉬，藉此可以進一步提升成型該桿頭後的抗拉強度，以及使該桿頭具有較佳的伸長率。 The molybdenum metal can stabilize the β phase of the titanium alloy, adding molybdenum to the golf club head alloy can increase the tensile strength of the club head made of the golf club head alloy, so that the club head is not easy to sink after hitting the ball. In addition, in another embodiment, the golf club head alloy may contain 2 parts by weight of molybdenum, so that the tensile strength of the club head after molding can be further improved, and the club head has better elongation.
釩金屬為β相穩定元素的同晶元素，釩在β相中具有較佳的固溶度。也就是說，釩溶入合金晶格後可維持晶格的穩定，故於高爾夫球桿頭合金中添加釩，可提升該桿頭的強度。然而，過高的釩會導致桿頭的成型率下降，過低又會使得桿頭的機械強度不佳。因此，在另一實施例中，該高爾夫球桿頭合金可以包含2重量份之釩，使得高爾夫球桿頭合金製成桿頭本體或打擊面板時，具有較佳的成型率以及較佳的強度。此外，該高爾夫球桿頭合金可以包含1.7重量份的鉻以及0.3重量份的矽，使得該高爾夫球桿頭較佳的強度。 Vanadium metal is an isomorphic element of β-phase stable elements, and vanadium has better solid solubility in β-phase. That is to say, after vanadium dissolves into the alloy lattice, it can maintain the stability of the lattice, so adding vanadium to the golf club head alloy can increase the strength of the golf club head. However, too high vanadium will lead to lower molding rate of the club head, and too low vanadium will lead to poor mechanical strength of the club head. Therefore, in another embodiment, the golf club head alloy may contain 2 parts by weight of vanadium, so that when the golf club head alloy is made into a club head body or a face plate, it has better molding rate and better strength . In addition, the golf club head alloy may contain 1.7 parts by weight of chromium and 0.3 parts by weight of silicon, so that the golf club head has better strength.
值得注意的是，合金晶體中的原子會因為局部不規則的排列，而造成晶體晶格排列的錯位移動稱為差排滑移(Dislocation)，差排滑移被視為合金中的缺陷，係會造成金屬的變形，如果可以避免差排滑移的發生就可以使金屬硬化。而鐵原子可對上述差排滑移形成阻礙，因此，添加鐵可以提升合金的抗拉強度。在另一實施例中，該高爾夫球桿頭合金可以包含1重量份之鐵，以使該高爾夫球桿頭合金製成的桿頭本體或打擊面板時，具有較佳的強度。 It is worth noting that the atoms in the alloy crystal will cause the dislocation movement of the crystal lattice arrangement due to the local irregular arrangement, which is called dislocation slip (Dislocation). Dislocation slip is regarded as a defect in the alloy. It will cause deformation of the metal and harden the metal if misalignment slip can be avoided. Iron atoms can hinder the dislocation slip mentioned above, therefore, the addition of iron can improve the tensile strength of the alloy. In another embodiment, the golf club head alloy may contain 1 part by weight of iron, so that the club head body or face plate made of the golf club head alloy has better strength.
據此，工者在利用前述之該高爾夫球桿頭合金成型一高爾夫球桿頭後，該高爾夫球桿頭可以具有較佳的機械強度，且優於以習知鈦合金所 得的高爾夫球桿頭。此外，該高爾夫球桿頭合金具有佳的伸長率而容易成型，因此可以具有較佳的成型率。 Accordingly, after the workers use the aforementioned golf club head alloy to form a golf club head, the golf club head can have better mechanical strength, which is better than those made of conventional titanium alloys. Got golf club head. In addition, the golf club head alloy has good elongation and is easy to form, so it can have a good forming rate.
為了證實以本發明高爾夫球桿頭合金組成確實具有良好的強度，遂測量如第1表所示的習知鈦合金(第1組)以及本發明之一實施例的鈦合金(第2組)分別經熱軋成型一板材，並經830℃、6分鐘的熱壓鍛造成型為打擊面板後的機械性質，其結果如第2表所示。 In order to confirm that the composition of the golf club head alloy of the present invention does have good strength, the conventional titanium alloy (group 1) as shown in Table 1 and the titanium alloy of an embodiment of the present invention (group 2) were measured The mechanical properties of a panel were formed by hot rolling and hot press forging at 830°C for 6 minutes. The results are shown in Table 2.
依據上述試驗結果可知，以本發明高爾夫球桿頭合金製成的打擊面板(第2組)之抗拉強度及降伏強度，皆高於習知鈦合金(第1組)所製成之打擊面板。再者，相較於習知鈦合金，本發明高爾夫球桿頭合金藉由較高的釩含量，進而可以提升了本發明高爾夫球桿頭合金製成的高爾夫球桿頭的強度。 According to the above test results, it can be seen that the tensile strength and yield strength of the hitting faceplate (group 2) made of the golf club head alloy of the present invention are higher than those of the hitting faceplate made of the conventional titanium alloy (group 1) . Furthermore, compared with the conventional titanium alloy, the golf club head alloy of the present invention has a higher vanadium content, thereby improving the strength of the golf club head made of the golf club head alloy of the present invention.
此外，硼(B)添加於鈦合金中可以有效地細化鈦合金的晶粒，可以避免例如成型製成高爾夫球桿頭本體或打擊面板時，所造成的桿頭本體或打擊面板的晶粒粗大，進而可以避免機械性質的降低。因此，本發明高爾夫球桿頭合金的第二實施例，係可以包含5.5~8重量份之鋁、1.7~3.3重量 份之鉬、1.7~2.3重量份之釩、小於或等於2重量份且不為0之鉻、小於或等於0.35重量份且不為0之矽、0.25~1.3重量份之鐵、0.05~0.2重量份的硼以及平衡量的鈦。具體而言，該高爾夫球桿頭合金可以包含7.5重量份之鋁、3重量份之鉬、2重量份之釩、1.5重量份之鉻、0.25重量份之鐵、0.1重量份的硼以及平衡量的鈦。 In addition, the addition of boron (B) to the titanium alloy can effectively refine the grains of the titanium alloy, and can avoid, for example, the grains of the club head body or the impact panel caused by molding the golf club head body or the impact panel. Coarse, thereby avoiding the reduction of mechanical properties.
