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 (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 (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.
