摘要： 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.

摘要： 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.

摘要： A method includes forming an as-grown film of a superconductor composed of a MgB2 compound which is made by simultaneous evaporation of magnesium and boron. The as-grown film is superconductive without an annealing process to make the film superconductive. The method can be applied to fabricate an integrated circuit of the superconductor film, because a high temperature annealing process to make the as-grown film superconductive is not needed.
