Abstract
A method for the manufacture of highly loadable components by precision forging, e.g., of gas turbine compressor blades with different stress zones, initially provides for the production of a preform in a one-step forming operation, e.g., casting or sintering, with further deformable volume zones with a certain volume concentration in the highly loaded areas. The preform is subsequently finish-forged at a deformation rate which is limited by the respective volumes and is merely directed to the load and strength-specific recrystallization and structural requirements in the critical stress zones of the component.

A method for the manufacture by precision forging of highly loadable components with different stress and volume zones, comprising:
- initially producing in a one-step forming operation a preform of the respective highly loadable component, the perform having further deformable volume zones of certain respective sizes in respective critical stress zones, and subsequently finish forging the preform at a deformation rate which is limited by the volumes available and is merely directed to load and strength-specific structural requirements in the critical stress zones of the finished component.
