Abstract:The isothermal forging of difficult-to-deformation materials is one of the advanced hot working processes in the world. From our research and the application of achievements, the research progresses of isothermal forging technology of titanium alloys from simple disks to complicated structure components, from medium and small-sized forgings to large and whole ones from homogeneous forgings to functionally graded forgings were introduced and analyzed. Finally, the future trend and development of isothermal forging technology were discussed.
Key words: titanium alloys material; superplasticity; isothermal precision die forging; whole bulkhead; dual property disk
