ABSTRACT:
A process for making a work piece from a β-type titanium alloy material includes subjecting the β-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 β-type titanium alloy material, and then subjecting the β-type titanium alloy material to an aging treatment.
