Description
本發明係關於一種合金，尤其是一種高爾夫球桿頭合金。The present invention relates to an alloy, and more particularly to a golf club head alloy.
鈦合金（例如，Ti-811）因兼具良好的強度及韌性，所以被廣泛的用以作為高爾夫球桿頭合金，習知的Ti-811合金所製成之高爾夫球桿頭，雖然具有良好的機械性質，然而仍具有較高的比重，而在高爾夫球桿頭的設計上有所限制。有鑑於此，習知的Ti-811高爾夫球桿頭確實仍有加以改善之必要。Titanium alloys (e.g., Ti-811) are widely used as golf club head alloys because of their good strength and toughness. Although the golf club heads made of the conventional Ti-811 alloy have good mechanical properties, they still have a high specific gravity, which limits the design of the golf club heads. In view of this, the conventional Ti-811 golf club heads still need to be improved.
為解決上述問題，本發明的目的是提供一種高爾夫球桿頭合金，係可以用以製造低密度之高爾夫球桿頭者。To solve the above problems, the object of the present invention is to provide a golf club head alloy that can be used to manufacture a low-density golf club head.
本發明以下所述方向性或其近似用語，例如「前」、「後」、「左」、「右」、「上（頂）」、「下（底）」、「內」、「外」、「側面」等，主要係參考附加圖式的方向，各方向性或其近似用語僅用以輔助說明及理解本發明的各實施例，非用以限制本發明。The directions or similar terms used in the present invention, such as "front", "rear", "left", "right", "upper (top)", "lower (bottom)", "inside", "outside", "side", etc., are mainly used with reference to the directions of the attached drawings. Each direction or its similar terms are only used to assist in the description and understanding of the various embodiments of the present invention, and are not used to limit the present invention.
本發明的高爾夫球桿頭合金，包含：以重量百分比計為8～9%之鋁、1.5～2.5%之釩、0.1～0.4%的鐵及0.05～0.15%的氧，其餘比例為平衡量的鈦及不可避免之雜質；且該高爾夫球桿頭合金的密度為4.325～4.335 g/cm3。The golf club head alloy of the present invention comprises: by weight percentage, 8-9% aluminum, 1.5-2.5% vanadium, 0.1-0.4% iron and 0.05-0.15% oxygen, and the remaining proportion is a balanced amount of titanium and inevitable impurities; and the density of the golf club head alloy is 4.325-4.335 g/cm3.
據此，藉由本發明之高爾夫球桿頭合金的組成配比，使該高爾夫球桿頭合金的密度約為4.325～4.335 g/cm 3，因而可以應用於製造獲得輕量之高爾夫球桿頭，可以達到同時維持高爾夫球桿頭高強度及輕量化的功效。 Therefore, the golf club head alloy of the present invention has a density of about 4.325-4.335 g/cm 3 , and can be used to manufacture a lightweight golf club head, thereby achieving the effect of maintaining high strength and lightweight of the golf club head.
其中，該高爾夫球桿頭合金的鉬當量符合下列公式：[Mo] eq=0.67[V]+2.9[Fe]-1.0[Al]。如此，可以進一步調整該高爾夫球桿頭合金之組成、及含有之微量元素比例，除了可以使該高爾夫球桿頭合金具有較低的密度之外，並可以提升該高爾夫球桿頭合金的軋延率以及增加後續製程的成形率的效果。 The molybdenum equivalent of the golf club head alloy complies with the following formula: [Mo] eq = 0.67[V] + 2.9[Fe] - 1.0[Al]. In this way, the composition of the golf club head alloy and the proportion of trace elements contained therein can be further adjusted. In addition to making the golf club head alloy have a lower density, the rolling rate of the golf club head alloy can be improved and the forming rate of the subsequent process can be increased.
其中，該高爾夫球桿頭合金的鉬當量為-6.325～-7.995。如此，係具有避免該鉬當量過高，造成高爾夫球桿頭成型率的下降的效果。The molybdenum equivalent of the golf club head alloy is -6.325 to -7.995, which can prevent the molybdenum equivalent from being too high, thereby reducing the forming rate of the golf club head.
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，作詳細說明如下：In order to make the above and other purposes, features and advantages of the present invention more clearly understood, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings as follows:
本發明之高爾夫球桿頭合金係可以包含：以重量百分比計為8～9%之鋁（Al）、1.5～2.5%之釩（V），平衡量的鈦（Ti）及不可避免之雜質，較佳可以包含以重量百分比計為：8.25～8.75%之鋁，及1.75～2.25%之釩；該高爾夫球桿頭合金的密度約為4.325～4.335 g/cm 3，藉由調整該高爾夫球桿頭合金的組成配比，可以使該高爾夫球桿頭合金具有較低的密度。另，為了進一步提升該高爾夫球桿頭合金的機械性質，係可以另包含以重量百分比計為0.1～0.4%之鐵（Fe）及0.05～0.15%之氧（O）。 The golf club head alloy of the present invention may include: 8-9% aluminum (Al), 1.5-2.5% vanadium (V), a balance of titanium (Ti) and inevitable impurities by weight percentage, preferably 8.25-8.75% aluminum and 1.75-2.25% vanadium by weight percentage; the density of the golf club head alloy is about 4.325-4.335 g/cm 3 , and the golf club head alloy can have a lower density by adjusting the composition ratio of the golf club head alloy. In addition, in order to further improve the mechanical properties of the golf club head alloy, it may further include 0.1-0.4% iron (Fe) and 0.05-0.15% oxygen (O) by weight percentage.
該高爾夫球桿頭合金之組成較佳具有一鉬當量（[Mo] eq），該鉬當量係影響合金熔融的流動性，而影響高爾夫球桿頭的成型率，本實施例中，該鉬當量可以為-6.325～-7.995，以避免該鉬當量過高，造成高爾夫球桿頭成型率的下降。詳言之，該高爾夫球桿頭合金之鉬當量較佳符合下列公式：[Mo] eq=0.67[V]+2.9[Fe]-1.0[Al]，藉此，可以進一步調整該高爾夫球桿頭合金之組成、及含有之微量元素比例，除了可以使該高爾夫球桿頭合金具有較低的密度之外，並可以提升該高爾夫球桿頭合金的軋延率以及增加後續製程的成形率。 The composition of the golf club head alloy preferably has a molybdenum equivalent ([Mo] eq ), which affects the fluidity of the molten alloy and thus affects the forming rate of the golf club head. In this embodiment, the molybdenum equivalent can be -6.325 to -7.995 to avoid the molybdenum equivalent being too high, which causes a decrease in the forming rate of the golf club head. Specifically, the molybdenum equivalent of the golf club head alloy preferably conforms to the following formula: [Mo] eq = 0.67[V] + 2.9[Fe] - 1.0[Al]. Thus, the composition of the golf club head alloy and the proportion of trace elements contained therein can be further adjusted. In addition to making the golf club head alloy have a lower density, the rolling rate of the golf club head alloy can be improved and the forming rate of subsequent processes can be increased.
為了證實本發明高爾夫球桿頭合金確實可以兼具低密度及高強度，遂測量如第1表所示的本發明之一實施例（第1a組）及習知Ti-811合金（第2a組）之機械性質及密度，其結果如第2表所示。In order to verify that the golf club head alloy of the present invention can indeed have both low density and high strength, the mechanical properties and density of an embodiment of the present invention (Group 1a) and the known Ti-811 alloy (Group 2a) as shown in Table 1 were measured, and 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
第2表、本試驗各組合金之機械性質
依據上述試驗結果可以得知，相較於習知高爾夫球桿頭合金Ti-811（第2a組）的密度，本發明高爾夫球桿頭合金（第1a組）的密度較低，因此可以製作獲得的高爾夫球桿頭的重量較輕；並且，本發明高爾夫球桿頭合金之機械性質亦高於習知高爾夫球桿頭合金Ti-811。證實本發明高爾夫球桿頭合金確實可以在維持高強度的同時，形成較低密度的合金。According to the above test results, the density of the golf club head alloy (Group 1a) of the present invention is lower than that of the conventional golf club head alloy Ti-811 (Group 2a), so the golf club head obtained can be made lighter; and the mechanical properties of the golf club head alloy of the present invention are also higher than those of the conventional golf club head alloy Ti-811. It is confirmed that the golf club head alloy of the present invention can indeed form an alloy with a lower density while maintaining high strength.
另，係比較本發明高爾夫球桿頭合金之不同組成比例對機械性質的影響，遂測量如第3表所示不同釩之比例合金（第1b～5b組）的機械性質及密度，其結果如第4表所示。In addition, the effects of different composition ratios of the golf club head alloy of the present invention on the mechanical properties were compared. The mechanical properties and density of the alloys with different vanadium ratios (groups 1b to 5b) as shown in Table 3 were measured. The results are shown in Table 4.
第3表、本試驗各組高爾夫球桿頭合金的組成配比
第4表、本試驗不同合金組成之機械性質
依據上述試驗結果可以得知，當該高爾夫球桿頭合金的釩比例小於重量百分比計為1.5%時（第1b組），機械性質較差，當該高爾夫球桿頭合金的釩比例為1.5～2.5%時（第2b～3b組），具有較好的機械性質及較低的密度，而，當該高爾夫球桿頭合金的釩比例大於2.5%時（第5b組），雖有較好的機械性質，但密度高成型率也會下降。顯示，本發明高爾夫球頭合金之釩含量為1.5～2.5%時，具有較佳的機械性質，並且兼具低密度及良好的成型率。According to the above test results, when the vanadium content of the golf club head alloy is less than 1.5% by weight (Group 1b), the mechanical properties are poor. When the vanadium content of the golf club head alloy is 1.5-2.5% (Groups 2b-3b), it has better mechanical properties and lower density. When the vanadium content of the golf club head alloy is greater than 2.5% (Group 5b), although it has better mechanical properties, the high density will also reduce the forming rate. It shows that when the vanadium content of the golf club head alloy of the present invention is 1.5-2.5%, it has better mechanical properties, low density and good forming rate.
綜上所述，本發明的高爾夫球桿頭合金，藉由本發明之高爾夫球桿頭合金的組成配比，使該高爾夫球桿頭合金的密度約為4.325～4.335 g/cm 3，因而可以應用於製造獲得輕量之高爾夫球桿頭，可以達到同時維持高爾夫球桿頭高強度及輕量化的功效。 In summary, the golf club head alloy of the present invention has a density of about 4.325-4.335 g/cm 3 due to the composition ratio of the golf club head alloy of the present invention, and can be used to manufacture a lightweight golf club head, thereby achieving the effect of maintaining high strength and lightweight of the golf club head.
雖然本發明已利用上述較佳實施例揭示，然其並非用以限定本發明，任何熟習此技藝者在不脫離本發明之精神和範圍之內，相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been disclosed using the above preferred embodiments, they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the scope of protection of the present invention shall be subject to the scope of the attached patent application.
