摘要:
Process for production of metallic components by warm forming of blanks of alloys with superplastic micro-structure, wherein the deforming pressure in the deforming tool is kept at least 20% below the deformation pressure necessary for forging of the respective alloy without superplastic micro-structure, and the expansion rate ({acute over (ε)}) of the warm forming is adjusted to a value above 0.1/s, or wherein the expansion of the blank during The warm forming is maintained below 50% of the expansion value achievable by a superplastic deforming and the expansion rate ({acute over (ε)}) which is at least the 100 fold of that for superplastic deformation, as well as drive shafts, gears, pinions or profile pans obtainable thereby.
