Embodiment Construction

[0033]In order to make the above-mentioned and other objects, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention will be exemplified below and described in detail in conjunction with the accompanying drawings. Furthermore, the directional terms mentioned in the present invention, such as up, down, top, bottom, front, rear, left, right, inner, outer, side, surrounding, center, horizontal, lateral, vertical, longitudinal, axial, Radial, uppermost or lowermost, etc., are only directions with reference to the attached drawings. Also, references to the singular forms "a", "an" and "the" herein include plural references unless the context clearly dictates otherwise. The numerical range (such as 10% to 11% of A) includes upper and lower limits unless otherwise specified (ie 10%≦A≦11%); if the numerical range does not define the lower limit (such as B below 0.2%) , or B) below 0.2%, it means that th...

Abstract

The present invention discloses a duplex-phase golf club head titanium alloy, which contains 6.0-7.5 wt% of aluminum, 1.5-2.5 wt% of vanadium, 1.5-2.5 wt% of chromium, 0.1-0.5 wt% of iron, 1.5-2.5 wt%of tin, 1.5-2.5 wt% of zirconium, 0.1-0.5 wt% of silicon, and other trace elements inevitable in an alloy material manufacturing process and with the ratio by using titanium as a base material. According to the present invention, after the duplex-phase golf club head titanium alloy is subjected to 780-840 DEG C plastic processing and heat treatment, the alloy structure with the alpha phase and the beta phase can be obtained; and due to the combination of the multiple alloying elements, the subgrain and high-density differential arrangement structure is generated in the alloy matrix, and the trace amount of the fine omega-phase precipitate can be formed, such that the duplex-phase golf ball bar head titanium alloy can have the tensile strength of 1300-1450 MPa, have the yield strength of 1250-1400 MPa, and the elongation of 6-12% so as to improve the design space of the golf club head structure.

Description

technical field [0001] The present invention relates to a duplex phase golf club head titanium alloy comprising: 6.0 to 7.0 wt % aluminum, 1.5 to 2.5 wt % tin, 1.5 to 2.5 wt % zirconium, 1.5 to 2.5 wt % % vanadium, 1.5 to 2.5 wt % chromium, 0.1 to 0.5 wt % iron, 0.05 to 0.20 wt % silicon. After proper plastic working and heat treatment, the basic microstructure of the alloy is bimodal, with the characteristics of secondary grains and high density dislocation, as well as a small amount of ω-phase precipitates. Background technique [0002] In golf equipment, several clubs for different purposes are classified into wooden clubs, irons and putters according to their functions. The clubs for different uses are made of various alloy materials. Among them, 3-5 wood heads, 7-8 iron heads, 1 pitching head (PW), 1 sand pit head (SW), and 1 putter 1 putter. It is described as follows: [0003] 1. Wood head: The wood head is mainly based on the driver, which is required to play far...
