    • An α+β-type titanium alloy which, has a high Young's modulus and strength-ductility balance is provided as a material for a face of a driver, iron, or other golf club.A titanium alloy having a high strength and high Young's modulus for a golf club face comprising, by mass %, 4.7 to 5.5% of Al, 0.5 to 1.4% of Fe, 0.03% or less of N, O which satisfies an [O] eq (oxygen equivalent value) of 0.25 to 0.34% calculated by formula (1), and a balance of Ti and unavoidable impurities. By adding Al, O, and N which cause solution strengthening of the α-phase and selecting the inexpensive Fe as the β-stabilizing element and suitably limiting the amounts of addition of these elements, it is possible to achieve a high strength and a high Young's modulus which satisfies the SLE rule without relying on cold working strengthening or aging strengthening heat treatment, and simultaneously obtain a large, good total elongation and a high strength-ductility balance.

    • The present invention provides, as a material for a golf club face of a driver, an iron or the like, a titanium alloy which satisfies the regulation for a coefficient of restitution, and has high Young's modulus and tensile strength and also has excellent hot and cold workability. The titanium alloy for a golf club face according to the present invention comprises, in percent by mass, 1.0 to 3.5% of Al, 0.5 to 1.4% of Fe, 0.2 to 0.5% or O and 0.002 to 0.030% of N, and the balance of Ti with inevitable impurities, wherein an α-phase is strengthened by combined addition of O and Al, and inexpensive Fe is selected as a β-phase stabilizing element, leading to high strength and high Young's modulus in combination. The content of Al causing deterioration of hot workability is limited to a low value, leading to low rolling load during hot rolling, and thus flaws and edge cracking are unlikely to occur during hot rolling.
    • 本发明提供作为驱动器的高尔夫球杆面的材料,铁等,满足恢复系数的规定的钛合金,并且具有高的杨氏模量和拉伸强度,并且还具有优异的热和 冷加工性。 根据本发明的用于高尔夫球杆面的钛合金以质量百分比计包含1.0-3.5%的Al,0.5-1.4%的Fe,0.2-0.5%的O和0.002到0.030%的N,并且 Ti与不可避免的杂质的平衡,其中α相通过O和Al的组合加成而被加强,并且廉价的Fe被选择作为相稳定元件,导致高强度和高杨氏模量的组合。 热加工性劣化的Al的含量被限制在低值,导致热轧时的低轧制负荷,因此在热轧时不易发生缺陷和边缘裂纹。
