Therefore, the composition alloy of the present invention limits the carbon element to the sub-peritectic region and is strictly set to between 0.08-0.12wt% (for example, based on the total weight of the composition alloy of a golf iron head being 100wt%).
錳(Mn)與矽(Si)：在本發明的組成合金內添加矽時，有利於防止氣孔形成、增進收縮作用，及增加鋼液流動性，而能增加合金鑄件的鑄造性；錳容易與鐵共存，且易與硫結合，可作為脫硫劑，改善合金熱脆性，再者錳亦能去除合金中的氧化物；因此，本發明的組成合金錳與矽含量控制於0.8~1.5wt%(例如以高爾夫鐵桿頭的組成合金的總重為100wt%計)，將有助於改善合金鑄件的鑄造性。Manganese (Mn) and silicon (Si): When silicon is added to the composition alloy of the present invention, it is beneficial to prevent the formation of pores, promote shrinkage, and increase the fluidity of molten steel, thereby increasing the castability of alloy castings; manganese is easily combined with Iron coexists and easily combines with sulfur, which can be used as a desulfurizer to improve the thermal brittleness of the alloy. Furthermore, manganese can also remove oxides in the alloy; therefore, the manganese and silicon content of the composition alloy of the present invention is controlled at 0.8~1.5wt% (For example, based on the total weight of the alloy forming the golf iron head being 100wt%), it will help to improve the castability of alloy castings.
鉻(Cr)：本發明考量不生銹特徵與麻田散鐵結構基地，於合金中添加鉻元素，且為控制少量(3~10%)沃斯田鐵(γ)的存在。因此，本發明合金鉻含量控制在13.0~15.0wt%之間(例如以高爾夫鐵桿頭的組成合金的總重為100wt%計)。因鉻含量低於13.0wt%不利於抗蝕性的特徵，而鉻含量高於15wt%，則會存在部分肥粒鐵，不利於機械性質的特徵。Chromium (Cr): This invention takes into consideration the rust-free characteristics and the structural base of the loose iron, adding chromium element to the alloy, and controlling the presence of a small amount (3~10%) of the loose iron (γ). Therefore, the chromium content of the alloy of the present invention is controlled between 13.0 and 15.0wt% (for example, based on the total weight of the alloy constituting the golf iron head being 100wt%). Because the chromium content is less than 13.0wt%, it is not conducive to the corrosion resistance characteristics, and the chromium content is higher than 15wt%, there will be some fat particles, which is not conducive to the mechanical properties.
鎳(Ni)：本發明的合金添加鎳，主要為控制鎳元素使其結構具備3~10%沃斯田鐵比例，而使其延伸率不因強度提升而下降。因此，本發明的組成合金的鎳含量，為達少量沃斯田鐵的存在，嚴格控制在3.7~5.1wt%之間(例如以高爾夫鐵桿頭的組成合金的總重為100wt%計)。Nickel (Ni): Nickel is added to the alloy of the present invention, mainly to control the nickel element so that the structure has a proportion of 3 to 10% of Worthfield iron, so that the elongation does not decrease due to the increase in strength. Therefore, the nickel content of the composition alloy of the present invention, due to the presence of a small amount of Worthfield iron, is strictly controlled between 3.7 and 5.1 wt% (for example, based on the total weight of the composition alloy of a golf iron head being 100 wt%).
銅(Cu)：為增加強度，考量富銅相(Fe,Cu)析出，且避免形成完全的麻田散鐵組織結構形成。因此，本發明的組成合金限定銅元素，嚴格設定為0.5-1.2wt%之間(例如以高爾夫鐵桿頭的組成合金的總重為100wt%計)。Copper (Cu): In order to increase strength, consider the precipitation of copper-rich phases (Fe, Cu) and avoid the formation of a complete Asada loose iron structure. Therefore, the copper element in the composition alloy of the present invention is strictly set to be between 0.5-1.2wt% (for example, based on the total weight of the composition alloy of a golf iron head being 100wt%).
鉬(Cu)：鉬元素的設計，為考量(Mo,Cr) 23C 6或Mo 6C析出，以增加強度。因此，鉬元素設定為2.0-3.4wt%之間(例如以高爾夫鐵桿頭的組成合金的總重為100wt%計)。 Molybdenum (Cu): The molybdenum element is designed to consider the precipitation of (Mo,Cr) 23 C 6 or Mo 6 C to increase strength. Therefore, the molybdenum element is set to be between 2.0-3.4wt% (for example, based on the total weight of the alloy constituting the golf iron head being 100wt%).
鈮(Nb)：鈮元素的設計，為考量NbC析出，以增加強度。因此，鈮元素設定為0.25-0.4wt%之間(例如以高爾夫鐵桿頭的組成合金的總重為100wt%計)。Niobium (Nb): The design of niobium element takes into account the precipitation of NbC to increase strength. Therefore, the niobium element is set to be between 0.25-0.4wt% (for example, based on the total weight of the alloy constituting the golf iron head being 100wt%).
鈦(Ti)：鈦元素的設計，為考量TiC、TiNi、TiN的析出，以增加強度；且避免延伸率下降。鈦元素設定為0.1-0.3wt%之間(例如以高爾夫鐵桿頭的組成合金的總重為100wt%計)。Titanium (Ti): The design of titanium element takes into account the precipitation of TiC, TiNi, and TiN to increase strength and avoid a decrease in elongation. The titanium element is set to be between 0.1-0.3wt% (for example, based on the total weight of the alloy forming the golf iron head being 100wt%).
氮(N)：為考量TiN的析出或氮元素的固溶強化，以增加強度；且避免氣孔形成。氮元素設定為0.08-0.18wt%之間(例如以高爾夫鐵桿頭的組成合金的總重為100wt%計)。Nitrogen (N): To consider the precipitation of TiN or solid solution strengthening of nitrogen element to increase strength and avoid the formation of pores. The nitrogen element is set to be between 0.08-0.18wt% (for example, based on the total weight of the alloy forming the golf iron head being 100wt%).

It can be seen from this that the composition alloy of the golf iron head produced by the manufacturing method of the composition alloy of the golf iron head according to the embodiment of the present invention is indeed better than the traditional golf head.
接著，對實施例5進行進一步分析。首先，進行掃描式電子顯微鏡(SEM)觀察，顯示：可獲致(例如約96.0%)麻田散鐵組織，以及約4.0%沃斯田鐵組織，如圖2(低倍率)與圖3(高倍率)所示，其中麻田散鐵組織與沃斯田鐵組織例如是通過軟體(例如ImageJ與JAVA軟體(ImageJ bundled with 64-bit Java 1.8.0_172))分析SEM照片中來取得。從圖3顯示：麻田散鐵組織M、沃斯田鐵組織A、顆粒析出物P1以及微量氣孔H的存在。Next, Example 5 was further analyzed. First, scanning electron microscopy (SEM) observation is performed, which shows that (for example, about 96.0%) Hemp field iron structure and about 4.0% Worth field iron structure can be obtained, as shown in Figure 2 (low magnification) and Figure 3 (high magnification). ), where the Asada loose iron structure and the Worth field iron structure are obtained by analyzing SEM photos using software (such as ImageJ and JAVA software (ImageJ bundled with 64-bit Java 1.8.0_172)). Figure 3 shows: the existence of Asada loose iron structure M, Wasfield iron structure A, particle precipitates P1 and trace pores H.
之後，以穿透式電子顯微鏡(TEM)觀察一區域，如圖4所示：麻田散鐵組織主要為高密度錯位(dislocation)結構D。另外，同樣以穿透式電子顯微鏡(TEM)觀察另一區域，如圖5所示，於麻田散鐵組織的基地內，可觀察到顆粒狀析出物，並且圖5亦顯示：此顆粒析出物(即對應圖3的顆粒析出物P1)，具高鈦元素含量，為典型的TiC碳化物。要提到的是，這有別於目前商用不生銹之鑄造型高爾夫鐵桿頭，即目前商用不生銹之鑄造型高爾夫鐵桿頭不具有此種TiC碳化物。換言之，本發明的至少一特徵在於，具有TiC碳化物的顆粒狀析出物，可達到析出強化效果，增加高爾夫鐵桿頭的強度。Afterwards, a transmission electron microscope (TEM) was used to observe an area, as shown in Figure 4: the Asada bulk iron structure is mainly a high-density dislocation structure D. In addition, another area was also observed with a transmission electron microscope (TEM). As shown in Figure 5, granular precipitates can be observed in the base of the Asada loose iron structure, and Figure 5 also shows: This granular precipitate (Corresponding to the particle precipitate P1 in Figure 3), it has a high titanium content and is a typical TiC carbide. It should be mentioned that this is different from the current commercial rust-free cast golf iron heads, that is, the current commercial rust-free cast golf iron heads do not have such TiC carbide. In other words, at least one feature of the present invention is that having granular precipitates of TiC carbide can achieve a precipitation strengthening effect and increase the strength of the golf iron head.
此外，同樣以穿透式電子顯微鏡(TEM)觀察又一區域，如圖6所示，於沃斯田鐵組織A的基地內，可觀察到奈米級析出物，此將增加合金材料之強度，亦可避免因沃斯田鐵組織A形成，而降低合金材料之整體強度。在圖6的左上角的小圖是針對於析出物區域的繞射圖，其顯示：面心立方(FCC)結構的(111)軸之繞射點圖形(位於六角型頂點的位置B)，顯示此區域確實為沃斯田鐵組織A；另外，圖中亦存在M 23C 6的(100)軸之繞射點圖形(位於非六角型頂點的位置C)，顯示奈米級顆粒P2屬於M 23C 6析出物。此外，根據TEM-RDS成分分析，如圖7所示，顯示奈米級M 23C 6析出物具有高鉻與高鉬元素含量，為典型的(Cr,Mo) 23C 6碳化物。換言之，本發明的至少一特徵在於，合金材質具有少量沃斯田鐵存在，且於沃斯田鐵組織A的基地內，可觀察到奈米級(Cr,Mo) 23C 6碳化物析出，可達到析出強化效果，增加鐵桿頭之強度。 In addition, a transmission electron microscope (TEM) was also used to observe another area. As shown in Figure 6, nanoscale precipitates can be observed in the base of the Worthfield iron structure A, which will increase the strength of the alloy material. , it can also avoid the formation of Worthfield iron structure A, which will reduce the overall strength of the alloy material. The small picture in the upper left corner of Figure 6 is a diffraction pattern for the precipitate region, which shows: the diffraction point pattern of the (111) axis of the face-centered cubic (FCC) structure (located at the position B of the hexagonal vertex), It shows that this area is indeed Worthfield ferrostructure A; in addition, there is also a diffraction point pattern of the (100) axis of M 23 C 6 in the figure (located at the non-hexagonal vertex position C), showing that the nanoscale particle P2 belongs to M 23 C 6 precipitate. In addition, according to TEM-RDS composition analysis, as shown in Figure 7, it is shown that the nanoscale M 23 C 6 precipitate has high chromium and high molybdenum content and is a typical (Cr,Mo) 23 C 6 carbide. In other words, at least one feature of the present invention is that the alloy material has a small amount of Vostian iron, and in the base of the Vostian iron structure A, nanoscale (Cr,Mo) 23 C 6 carbide precipitation can be observed, It can achieve precipitation strengthening effect and increase the strength of iron head.
