The treatment methods are as follows:
1. Heat treatment: Improve the grain refinement of titanium alloy through heating and heat preservation.
2. Cold deformation: Cold deformation is the plastic deformation of titanium alloy through cold rolling, cold drawing, etc., thereby promoting the refinement of grains.
3. Precision forging: Deformation processing through precision forging technology can introduce high strain rate and complex shape deformation into titanium alloys.
