The scope of this work was the research of fundamentals to manufacture functional optimized components by partial hot stamping using locally different heated tools. One focus of this work was the identification of the influence of the deformation on the transformation kinetics of the boron-manganese steel 22MnB5, which was done by analyzing the impact of relevant process parameters on the resulting microstructure development. Furthermore, the impact of different contact conditions and process relevant parameters on the thermomechanical system tool-workpiece was investigated. Thereby, process characteristic values as the heat transfer coefficient were deter-mined as well as the resulting mechanical properties and microstructures developing in dependency of the different process pa-rameter settings and contact conditions were analyzed. For aspects of verification experiments using a model geometry and a demonstrator geometry have been performed supplemented by numerical calculations.
