Claims9
A titanium alloy bolt having a head and a portion to be threaded and extending from the head, the bolt being made of a Ti—Fe—O (titanium-iron-oxygen) alloy, having a tensile strength of at least 800 MPa and having a screw thread formed on the portion to be threaded by drawing and rolling.
A process for manufacturing a titanium alloy bolt, comprising the steps of:
- preparing a blank of a titanium-iron-oxygen alloy;
- subjecting the blank to plastic working at ambient temperature;
- and
- subjecting a product of the plastic working to screw thread forming.
