New description: [New technical field] This creation is about the design of a 'German ball', especially for a golf club made of duplex steel. [Prior Art] Golf has become a sporty style, and it is an advantage for the age-old people. = The result is divided into wooden, does not cause and = material 枓 ' ' and the club has carbon fiber material and gold for example 'Because ~ does not record steel with good golf clubs related to most of the same manufacturer The club is made of SI with the golf club and its ball head due to the type and form: different, two habits: the swing speed, etc., the position of the difference is poor <heavy;; the left skew occurs, that is The ball-weight golf club is not suitable for the user. Therefore, if it is made, if the material f can be the same volume and hardness, the ball and the weight of the ball are increased by the same hardness and weight. By. The size of the Shuo Shuo, used to mention the 'two Erfu clubs stinking strong sounds in the ancient shape in the rod shape and the club's general process magic side curling winding" "峨维, complex tape fixed in 3 M435287, by After warming and pressurizing, 'extracted shaped iron is hardened into a hollow carbon fiber tubular club. Month <=* The use of Γΐ, the entire club is made of carbon fiber, but in reality, the heart is. Although the carbon fiber itself is high in strength and extremely light; the production = the golf club is in the holding position _ the lack of sexuality does not affect the impact, the precision effect. In addition, the knot: the long-term support load of the ball is easy to make the club break. The = set: = carbon fiber, you must worry about adjusting the most curved U 2 = to avoid the concern about the strength of the club. Also = the ball position lacks better strength, so the size of the ball is small, the design is time consuming, and the intubation of the ball head: the strength of the force is considered. Therefore, the design range of the intubation is monotonous and variability due to the trend of the club. low. [Contents of the work] It is to provide a technical method that is made of duplex steel and is not solved. Department A is the technical means used to solve the problems of the prior art, and the golf clubs made of J two (four) dual-phase steel include - the head and the metal material with the double phase steel. The head member, the cast head member has a forged t 铒 2 including a " phase steel _ : to form a shaft body. In one of the practical examples of the palladium, the duplex steel has a stainless steel metal of two metallographic structures of a nose and a ferrite. In one embodiment of the present invention, the double head is identical to the shaft. Duplex steel. In one embodiment of the present invention, the shaft has a shaft body formed by drawing the steel and integrally forming the head. In another embodiment of the present invention, the head has a steel casting and/or forging and the shaft-body forming head is in the embodiment of the present invention. The shaft body 1 grip portion is The double-phase steel metal y in the shaft member is formed to have a gripping surface. In addition, the surface of the surface is ground. In addition, this creation is a skill-solving hand for solving the conventional technology. It is a kind of golf club, including a rod, a forged rod head L. pomelo:: structure, with -m sign in the head The head member and the head of the club head are made of - double metal material (four) into four (4) into a shaft member and one example in the case of 'dual phase steel with austenite. In the case of the technical hand slaves of the high-altitude steel, the material of the 胄 phase steel (4) is compared to the golf club made of the traditional material J carbon material. In the second pole, the process performance, cold forming performance and heat treatment performance are far and wide. Therefore, when heat-treating the head and the shaft of the creation:: In addition, the toughness of the duplex steel is high, so it is cast and The low forging transition temperature 'indirectly makes the clinker structure's intergranular corrosion welding performance significantly improved, while retaining the two advantages of the traditional material', for example, high thermal conductivity, small coefficient of linear expansion, superplasticity of M435287, It has properties such as magnetism. Therefore, the high-strength steel used in this creation, the strength of the double-phase steel used, especially in the manufacture of the Shantou club, the shape of the hammer is improved, and the plasticity of the club is required, so the sphericity is required. Approximately 30-50% less than conventional materials' is beneficial to reduce material costs and club thickness. Furthermore, under the conditions of dynamic load or static load, the duplex steel used in this work has higher energy absorption capacity than conventional materials, and is resistant to intergranular impurities, stress corrosion resistance, and corrosion resistance to traditional materials. The golf clubs have more obvious modifications (4). The details will be further explained by the example and the attached drawings. Λ [Embodiment] ▲ Refer to the 1®**'s side view. This is a three-dimensional schematic diagram of a double-phase steel. The golf club of this creation has just one head i and one shaft 2. The head i includes a prayer, and the head member 11 has a forged head surface (4). The body 1 includes a shaft member 21 which is drawn.

The body 2 includes a grip portion 22 which is ground on the outer surface of the duplex steel of the rod 1 21 to form a weir surface 222. Of course, the grip portion 22 can also be generally disposed. The structure of the package is shown here only in a preferred embodiment. In addition, the double-phase steel of the shaft 2 ^ ^ head 1 is made of pomelo and formed into a solid body with the head '. Similarly, the head 1 has a duplex steel from the shaft 2 and is cast by 6 M435287 and/or A head body that is forged and integrally formed with the shaft 2. In this creation, the duplex steel of the head 1 is substantially the same as the duplex steel of the shaft 2, and the double-phase steel metal material used in the double-phase steel has an austenite and a ferrite. Metallographic structure of stainless steel metal. In this embodiment, the metal material of the dual phase steel has a chromium metal content of about 22% and a nickel metal content of about 5%. Of course, the duplex steel may also be composed of metals including other proportions, and The above is limited. Among them, the dual-phase steel controls the content of alloying elements in the stainless steel by appropriately increasing the chromium equivalent or reducing the nickel equivalent. Therefore, the various characteristics of the dual-phase steel made of the golf club 100 of the present invention can be known from the following figures. : Dual phase steel (SAF2205) Numerical/characteristic thermal expansion coefficient (μπι/m ·°〇13.2 Heat conduction (w/m ·!〇21.0 Magnetic ferromagnetic drop strength (N/mm2) 450 Tensile strength (N/mm2) 680~ 900 Elongation (%) 25 Vickers hardness (HV) 260 The austenitic + ferrite duplex steel of the golf club 100 of the present invention refers to both austenite and ferrite structure in stainless steel. The steel grade, and the two-phase structure is independent, 'the content is large, and is also called α + r duplex stainless steel. Because of the α + r two-phase structure structure', the duplex steel used in this creation has both austenite Characteristics of stainless steel and ferritic stainless steel. Cold-working can be done in the process of golf club 1 (8) made of duplex steel and golf club HH made of golf ball made of general 7 stainless steel (ferritic stainless steel) ^| Type 旎 is far superior to ferrite Stainless steel, and the heat treatment performance is far superior to that of the body, so it can be precisely controlled when heat-treating the head and the shaft of the creation. In addition, the α + τ dual-phase steel has high high-strength, so it is The low brittleness transition temperature during forging' indirectly makes the energy and welding performance of the crest structure of the club structure significantly improved, while retaining the characteristics of ferrite without recording steel, for example, high thermal conductivity, line The expansion coefficient is small, superplastic, magnetic, etc. Compared with austenitic stainless steel, the α 7 duplex steel used in the present invention has high strength, especially in the manufacture of the golf club 1 of the present embodiment. The yield strength of the body-formed club head is significantly improved, the yield strength is more than twice that of ordinary austenitic stainless steel, and the plastic toughness required for club forming is required. Therefore, the thickness of the club wall is higher than that of the commonly used austenite. The reduction of the body stainless steel by 30_50% is beneficial to reduce the material cost and the thickness of the club. In addition, the dual phase steel used in this creation has higher energy absorption capacity than the austenitic stainless steel under dynamic or static load conditions, and Resistance to crystal Corrosion, stress corrosion resistance, corrosion resistance and other performances are more obvious than golf clubs made of traditional stainless steel or metal alloy. As can be seen from the examples, the two-phase steel is provided by this creation. The Nanlf clubs have industrial use value, so the original operation has been in accordance with the requirements of the patent. However, the above description is only for the preferred embodiment of the creation, and those skilled in the art can Other improvements are described, but these changes are still within the creative spirit of this creation and the scope of patents defined below.
