The main objective of the performed investigations was to reveal a fundamental contribution to the characterization and description of the forming and the phase transformation behavior of the boron-manganese steel 22MnB5 according to the typical time-temperature-characteristic of the hot stamping process considering the main influencing process parameters. To meet this challenge within the scope of this work different experimental setups and methodologies had been established, which enable the analysis of the material properties at elevated temperatures as well as the determination of the essential thermal and tribological material process characteristics like heat transfer coefficient and friction coefficient regarding a FE-based process design of hot stamping.
