  • Process for making a work piece from a ?-type titanium alloy material
    Patent number: 7132021
    Abstract: A process for making a work piece from a ?-type titanium alloy material includes subjecting the ?-type titanium alloy material to cold working with controlling the reduction rate thereof to vary the reduction rate depending on a position across a plain direction of the ?-type titanium alloy material, and then subjecting the ?-type titanium alloy material to an aging treatment.

  • Process for making a plate for a golf club head face, and golf club head
    Publication number: 20050003901
    Abstract: A process for making a plate composed of a ?-type titanium alloy material for a golf club head face includes subjecting the ?-type titanium alloy material to cold working with controlling the reduction rate thereof to vary the reduction rate depending on a position across a plain direction of the ?-type titanium alloy material, and then subjecting the ?-type titanium alloy material to an aging treatment so as to build up a hardness distribution across the plain direction of the ?-type titanium alloy material.
