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 and other objects, features and advantages of the present invention more obvious and understandable, preferred embodiments of the present invention are illustrated below and described in detail with reference to the accompanying drawings; in addition, the same symbols are used in different drawings. are considered to be the same and their description 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 includes 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 shaped into a head body or a hitting panel of the golf club head, 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 contains 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 a metal selected from the group consisting of less than or equal to 2 parts by weight and not 0 of chromium, less than or equal to 0.35 parts by weight of silicon, 0.15 to 1.3 parts by weight of iron, 0.05 to 0.2 parts by weight of boron and 2.5 to 3.5 parts by weight of tin, and a balance of titanium. Among them, chromium, silicon, molybdenum and vanadium can make the head formed of the golf club head alloy have a predetermined strength. Moreover, molybdenum and vanadium can provide the golf club head alloy with better plasticity 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 by weight of molybdenum, 1.7-2.3 parts by weight of vanadium, 1.4-2 parts by weight 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, aluminum metal can stabilize the α phase of titanium alloy and improve the molding rate of golf club head alloy heads. However, too much aluminum can lead to brittleness of the club head, and too little aluminum can lead to poor molding rates. Therefore, in another embodiment, the golf club head alloy may include 7.5 parts by weight of aluminum, so that when the golf club head alloy is made into a club head, it has better molding rate and better strength.
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。Molybdenum metal can stabilize the beta phase of 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, making the club head less likely to dent after hitting the ball. In addition, in another embodiment, the golf club head alloy may include 2 parts by weight of molybdenum, thereby further improving the tensile strength after molding the club head and allowing the club head to have 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 isomorphous element of the β phase stabilizing element, and vanadium has better solid solubility in the β phase. In other words, vanadium can maintain the stability of the crystal lattice after being dissolved into the alloy crystal lattice. Therefore, adding vanadium to the golf club head alloy can improve the strength of the club head. However, too high a vanadium content will lead to a decrease in the club head's molding rate, and too low a vanadium content will result in 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 the golf club head alloy has better molding rate and better strength when made into the head body or the hitting panel. . In addition, the golf club head alloy may include 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 dislocation movement in the crystal lattice arrangement due to local irregular arrangement, which is called dislocation. Dislocation is regarded as a defect in the alloy. It will cause deformation of the metal. If the occurrence of differential slip can be avoided, the metal can be hardened. Iron atoms can hinder the above-mentioned differential slip. Therefore, adding 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 golf club head alloy has better strength when the club head body or hitting panel is made of the golf club head alloy.
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 workers use the aforementioned golf club head alloy to shape a golf club head, the golf club head can have better mechanical strength and is superior to golf club heads made from conventional titanium alloys. . 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 alloy composition of the golf club head of the present invention does have good strength, the conventional titanium alloy (Group 1) and the titanium alloy of one embodiment of the present invention (Group 2) as shown in Table 1 were measured. The mechanical properties of a plate were formed by hot rolling and hot press forging at 830°C for 6 minutes to form a strike panel. The results are shown in Table 2.
第1表、本試驗各組高爾夫球桿頭合金的組成配比（重量份）
第2表、各組所製成打擊面板之機械性質
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 striking panel made of the golf club head alloy of the present invention (Group 2) are higher than those of the striking panel made of the conventional titanium alloy (Group 1) . Furthermore, compared with conventional titanium alloys, 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.
