摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a plate material for the head face of a golf club, which is made of a β-type titanium alloy material and has a hardness distribution continuously changing in a face direction, and to provide a golf club head using the plate material. SOLUTION: In a process of manufacturing the plate material for the head face of the golf club with the use of the β-type titanium alloy material, this manufacturing method comprises cold-working the β-type titanium alloy material while controlling a rolling reduction for the material so as to be different in the face direction; and then aging it. Thereby, the head face acquires the distribution of hardness in the face direction. The manufacturing method preferably further comprises solution-treating the alloy material before cold working; controlling the rolling reduction given in the cold working so as to vary in the face direction from less than 10% for the minimum value to 35% or higher for the maximum value; and carrying out the aging treatment in the range of 300°C or higher but a β transus temperature or lower, and for a treatment time of 1 to 60 minutes.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a golf club head superior in repulsion. SOLUTION: This method for manufacturing a head of a golf club made from a β-type titanium alloy comprises forming the titanium alloy into the head by hot working so as to have a mixing structure of an α-phase having an average grain size of 0.1 to 10μm and a β-phase having an average grain size of 0.1 to 10 μm, and heat-treating it in a range of "β transformation temperature minus 450°C" or higher but lower than "β transformation temperature minus 100°C", for 15 minutes to 100 hours.Before the above heat treatment, the β-type titanium alloy may be heat-treated in the range of "β transformation temperature minus 100°C" or higher but lower than the β transformation temperature for 1 minute to 2 hours. The above hot working is conducted preferably in the range of "β transformation temperature minus 100°C" or higher but lower than the β transformation temperature so as to make a value (A) expressed in the following expression (1) to be 0.5 or higher: A=ä(ε 1 2 +ε 2 2 +ε 3 2 )×2/3} 0.5 (1), wherein (A) in the expression (1) is an equivalent strain; and ε 1 , ε 2 and ε 3 are logarithmic strains in principal directions.
