Embodiment 1

[0051] An alloy blank is provided, the alloy blank comprises 86.78 parts by weight of titanium, 2.8 parts by weight of zirconium, 5.1 parts by weight of aluminum, 0.03 parts by weight of carbon, 0.03 parts by weight of nitrogen, 0.06 parts by weight of oxygen, 1.5 parts by weight of chromium, 1.6 parts by weight iron, 1.0 parts by weight vanadium and 1.1 parts by weight molybdenum. Next, a hot rolling process is performed on the alloy blank at 850 to 950° C. to form the golf club head alloy (for example, rolled into a plate), wherein a crystal phase composition of the golf club head alloy is It includes an equiaxed double-phase structure, wherein the equiaxed double-phase structure includes an alpha titanium phase and a beta titanium phase.

Embodiment 2 to 6 and comparative example 1 to 3

[0053] The production methods of Examples 2 to 6 and Comparative Examples 1 to 3 are roughly the same as that of Example 1, but the proportions of ingredients used are different, as shown in Table 1 below (the unit of each ingredient is parts by weight (or wt%)).

[0054] Table 1

[0055]

[0056] Next, the mechanical properties of Examples 1 to 6 and Comparative Examples 1 to 3 were analyzed. The analysis results are shown in Table 2 below.

[0057] Table 2

[0058]

[0059]

[0060] As can be seen from the analysis results of the above table 2, embodiments 1 to 6 do possess low Young's modulus (between 80 and 100GPa), high tensile strength (between 1100 and 1250MPa), high yield strength (between 1000 to 1050MPa), and acceptable elongation. The mechanical properties of Comparative Examples 1 to 3 are high Young's modulus, low tensile strength and low yield strength, and the elongation of Comparative Examples 2 and 3 is too high, so Comparative Examples 1 to 3 do n...

Abstract

The invention discloses a golf club head alloy and a method for manufacturing same. The method for manufacturing the golf club head alloy comprises the steps of: providing an alloy blank comprising 0.1 to 10 parts by weight of zirconium and 77 to 99.9 parts by weight of titanium; hot rolling the alloy blank at 850 to 950 DEG C to form the golf club head alloy, wherein a crystal phase compositionof the golf club head alloy comprises an equiaxed crystal duplex structure, and the equiaxed crystal duplex structure comprises an alpha titanium phase and a beta titanium phase. The golf club head alloy manufacturing method of the present invention can be used to manufacture a golf club head alloy having a low Young's modulus, and the golf club head alloy can be used to increase the spring effect of the hitting face of the golf club head, thereby increasing the hitting distance.

Description

technical field [0001] The present invention relates to an alloy and its manufacturing method, in particular to a golf club head alloy and its manufacturing method. Background technique [0002] In the development process of golf club heads, from the early solid club heads, the weight and strength were low, and now the use of metal materials can make the club head strength higher and higher, and can reduce weight and improve the success rate of hitting the ball. Density and high strength alloy. Metal materials can be developed and applied to the manufacture of club heads through different processing methods and alloy elements, and can even be combined with non-metallic composite materials to create a club with better control, precision, distance and error tolerance. High best golf equipment. [0003] On the other hand, titanium alloys are also used in the field of golf club heads. In recent years, the design of titanium alloy club heads has gradually emphasized the develo...
