Description
本發明係關於一種合金及其製造方法，特別是一種高爾夫球桿頭合金及其製造方法。The present invention relates to an alloy and a method of manufacturing the same, and more particularly to a golf club head alloy and a method of manufacturing the same.
一般而言，為了符合不同使用者的需求，通常高爾夫球桿頭一體成型之套頸需要具有易於調整傾角之特性，以符合使用者之需求。因此，習用高爾夫球桿頭通常係以低硬度之軟鐵類材質製成，例如以低碳鋼或低合金鋼等材質製成，使得高爾夫球桿頭之套頸具有前述易於調整傾角之特性。然而，該些軟鐵類材質卻具有易於氧化而不耐鏽蝕之缺點。In general, in order to meet the needs of different users, the neck of the golf club head usually needs to have the characteristics of easy to adjust the inclination to meet the needs of the user. Therefore, the conventional golf club head is usually made of a soft iron material of low hardness, for example, made of a material such as low carbon steel or low alloy steel, so that the neck of the golf club head has the aforementioned characteristics of easy adjustment of the inclination angle. However, these soft iron materials have the disadvantage of being easily oxidized and not resistant to rust.
為改良上述缺點，中華民國公告第438610及460306號皆有揭示以以SUS17-4PH規格之不鏽鋼材質製成該高爾夫球桿頭，使得所製成之高爾夫球桿頭可同時具有低硬度及較佳之耐鏽蝕性。In order to improve the above disadvantages, the Republic of China Announcement Nos. 438610 and 460306 disclose that the golf club head is made of stainless steel material of SUS17-4PH size, so that the golf club head can be made with low hardness and better. Corrosion resistance.
該SUS17-4PH之機械性質及熱處理值分別如表一及表二所示。The mechanical properties and heat treatment values of the SUS17-4PH are shown in Tables 1 and 2, respectively.
表一、SUS17-4PH之機械性質(棒材理論值)Table 1. Mechanical properties of SUS17-4PH (the theoretical value of bars)
表二、SUS17-4PH之熱處理值Table 2, heat treatment value of SUS17-4PH
其中，表二中之註A的鑄造熱處理係指：固溶處理1040℃均溫60分鐘氮氣冷卻，時效處理580℃持溫90分鐘；註B的鑄造熱處理係指：固溶處理1040℃均溫60分鐘氮氣冷卻，時效處理538℃持溫240分鐘；註C的鑄造熱處理係指：固溶處理1040℃均溫60分鐘氮氣冷卻，時效處理482℃持溫240分鐘；註D的板材一般熱處理係指：固溶處理1040℃均溫60分鐘氮氣冷卻，時效處理482℃持溫240分鐘。Among them, the casting heat treatment of Note A in Table 2 means: solution treatment at 1040 ° C for 60 minutes, nitrogen cooling, aging treatment at 580 ° C for 90 minutes; injection B for casting heat treatment refers to: solution treatment at 1040 ° C. 60 minutes nitrogen cooling, aging treatment 538 ° C holding temperature 240 minutes; injection C casting heat treatment refers to: solution treatment 1040 ° C average temperature 60 minutes nitrogen cooling, aging treatment 482 ° C holding temperature 240 minutes; Refers to: solution treatment 1040 ° C average temperature 60 minutes nitrogen cooling, aging treatment 482 ° C holding temperature 240 minutes.
由表一及表二可得知，由於該SUS17-4PH不鏽鋼中，鎳成分所佔比例僅約4.0wt%，因此延性較差，且仍然具有較高之降伏強度值。若以該SUS17-4PH不鏽鋼作為高爾夫球桿頭之材質，則該高爾夫球桿頭可能因延性較差或降伏強度較高而造成調角不易之缺點。As can be seen from Tables 1 and 2, since the proportion of the nickel component in the SUS17-4PH stainless steel is only about 4.0% by weight, the ductility is poor and still has a high drop strength value. If the SUS17-4PH stainless steel is used as the material of the golf club head, the golf club head may have a disadvantage that the angle adjustment is not easy due to poor ductility or high lodging strength.
基於上述原因，其有必要進一步改良上述習用高爾夫球桿頭合金及其製作方法。For the above reasons, it is necessary to further improve the above-described conventional golf club head alloy and a method of manufacturing the same.

The method for manufacturing the golf club head alloy of the present invention mainly comprises a melting step S1, a ratio maintaining step S2 and a head casting step S3.
請、參照第1圖所示，本發明之熔融步驟S1係依序將母合金、鉻鐵、銅及鎳等配料加入高溫熔爐中，使該些配料熔融混合。更詳言之，前述該些以銅、鉻、鎳及鐵為主要成分之配料受高溫熔爐[例如高週波爐]熔融後，便混合形成具有特定組成比例及特定組成相之銅、鎳、鉻及鐵等元素之合金材質，以供後續做為高爾夫球桿頭之基材[matrix]。其中，本實施例所使用之母合金除鐵以外係包含以重量百分比計0.04%之碳、0.80%之矽、1.00%之錳、6.38%之鎳、22.9%之鉻、0.90%之鉬、0.03%之磷及0.01%之硫。當然，亦可依據需求變換成不同配料來源，而熔融形成具有相同組成比例之鐵合金材質。Referring to Fig. 1, the melting step S1 of the present invention sequentially adds a master alloy, ferrochrome, copper, and nickel to a high-temperature furnace to melt and mix the ingredients. More specifically, the above-mentioned ingredients mainly composed of copper, chromium, nickel and iron are melted by a high-temperature furnace [for example, a high-frequency furnace], and then mixed to form copper, nickel, and chromium having a specific composition ratio and a specific composition phase. And alloy materials such as iron for subsequent use as a substrate for golf club heads [matrix].

Of course, it can also be converted into different sources of ingredients according to requirements, and melted to form a ferroalloy material having the same composition ratio.
此外，本發明較佳係依特定熔融順序將母合金、矽鐵、錳鐵、鉻鐵、鉬鐵、銅、鎳等配料加入高溫熔爐[例如高週波爐]中進行合金熔煉製程，使得該熔融合金中另包含矽、錳及鉬等其他成分，進而使得熔煉出來之合金可具有適當之特性。再且，依特定熔融順序加入該些配料可以避免在配料熔融時發生沈澱現象及防止後續製成之桿頭成品良率低落之問題。再且，本實施例較佳係使用呈現細粒狀態之前述配料，並盡可能以少量多次之方式緩慢加入該高溫熔爐中，以避免因大量加入該配料，造成該配料無法完全熔融而黏結成團塊狀，進而造成使得高溫熔爐內部產生空穴或氣泡而產生危險性。In addition, the present invention preferably incorporates a master alloy, ferroniobium, ferromanganese, ferrochrome, ferromolybdenum, copper, nickel, and the like into a high-temperature furnace [eg, a high-frequency furnace] in a specific melting sequence to perform an alloy melting process to cause the melting. The alloy further contains other components such as lanthanum, manganese and molybdenum, so that the smelted alloy can have suitable characteristics. Further, the addition of the ingredients in a specific melting sequence avoids the occurrence of precipitation during the melting of the ingredients and prevents the subsequent yield of the finished head product from falling. Furthermore, the present embodiment preferably uses the aforementioned ingredients in a fine-grained state and slowly adds them to the high-temperature furnace as much as possible in a small number of times to avoid the fact that the ingredients are not completely melted and adhered due to the large amount of the ingredients. Forming agglomerates, which in turn causes the generation of voids or bubbles inside the high-temperature furnace, posing a hazard.
請再參照第1圖所示，本發明之比例維持步驟S2係使前述該些配料之重量百分比維持在：2.5~4.0%之銅、5.0~6.0%之鎳、15~18%之鉻，殘餘部分為鐵及不可避免之雜質，且使該銅/鎳比係為0.4~0.8，以使該些配料可共同形成同時兼具有沃斯田鐵相、肥粒鐵相及麻田散鐵相之組織。更詳言之，當前述配料依序加入高溫熔爐以形成熔融合金後，接著則取樣測量熔融合金之重量組成比例，以確保該配料之重量百分比維持在：2.5~4.0%之銅、5.0~6.0%之鎳及15~18%之鉻，殘餘部分為鐵(65~75%)及不可避免之雜質，且使該銅/鎳比為0.4~0.8。該熔融合金中銅的組成比例更佳係為2.8~3.5%(以重量百分比計)，鉻的更佳比例係為15.5~17%(以重量百分比計)。透過使該熔融合金維持於該特定之組成比例及銅/鎳比，使得該熔融合金冷卻固化後能形成兼具沃斯田鐵相[austenite]、肥粒鐵相[ferrite]及麻田散鐵相之合金材質。其中，本案透過提高該鎳之比例，以提升整體合金之延性；再且，若該熔融合金中之銅/鎳比低於0.4，則銅之比例相對較低，鎳之比例相對較高，冷卻固化後所形成之合金的強度可能不足；若該熔融合金中之銅/鎳比高於0.8，則銅之比例相對較高，鎳之比例相對較低，冷卻固化後所形成之合金的硬度可能過高，而不利於作為高爾夫球桿頭後續進行調角之動作。因此，本案另透過使該銅/鎳比介於0.4~0.8，使得該合金可同時具有低硬度及適當之強度。其中，該合金中可另包含其他金屬成分或部分雜質，例如其他金屬成分以重量百分比計為0.65~0.81%之矽、0.66~0.78%之錳或0.002~0.125%之鉬，雜質如碳(C)、硫(S)或者磷(P)等成分，以重量百分比計碳較佳係低於0.06%，硫較佳係低於0.019%，磷較佳係低於0.027%。Referring to FIG. 1 again, the ratio maintaining step S2 of the present invention maintains the weight percentage of the above ingredients in: 2.5 to 4.0% copper, 5.0 to 6.0% nickel, 15 to 18% chromium, and residual. Part of the iron and unavoidable impurities, and the copper / nickel ratio is 0.4 ~ 0.8, so that the ingredients can be formed together with both Worthfield iron phase, fat grain iron phase and Ma Tian iron phase organization. More specifically, when the foregoing ingredients are sequentially added to the high-temperature furnace to form a molten alloy, the weight composition ratio of the molten alloy is then sampled to ensure that the weight percentage of the ingredients is maintained at 2.5 to 4.0% of copper, 5.0 to 6.0. % nickel and 15~18% chromium, the remainder is iron (65~75%) and unavoidable impurities, and the copper/nickel ratio is 0.4~0.8. The composition ratio of copper in the molten alloy is more preferably 2.8 to 3.5% by weight, and a more preferable ratio of chromium is 15.5 to 17% by weight. By maintaining the molten alloy at the specific composition ratio and the copper/nickel ratio, the molten alloy can be cooled and solidified to form both the iron phase [austenite], the ferrite phase [ferrite], and the maitian iron phase. Alloy material. Among them, the case improves the ductility of the overall alloy by increasing the proportion of the nickel; furthermore, if the copper/nickel ratio in the molten alloy is less than 0.4, the proportion of copper is relatively low, and the proportion of nickel is relatively high, cooling The strength of the alloy formed after curing may be insufficient; if the copper/nickel ratio in the molten alloy is higher than 0.8, the proportion of copper is relatively high, the proportion of nickel is relatively low, and the hardness of the alloy formed after cooling and solidification may be Too high, not conducive to the subsequent adjustment of the role as a golf club head. Therefore, in this case, by making the copper/nickel ratio between 0.4 and 0.8, the alloy can have both low hardness and appropriate strength. Wherein, the alloy may further comprise other metal components or partial impurities, for example, other metal components are 0.65-0.81% by weight, 0.66-0.78% manganese or 0.002-0.125% molybdenum, impurities such as carbon (C).
