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.
