Abstract

Local carburization of semi-finished sheet material is a process variant to manufacture hot stamped parts with tailored properties. In this research project, the process combination of local carburization and hot stamping shall be qualified for carburization temperatures above 950 °C to reduce the required process time. The dependence of the mechanical properties and resulting microstructure on the process-relevant influencing factors will be determined by means of in-situ characterizations. Furthermore, the accuracy of the numerical simulation will be improved by extending existing material models. The material models will then be validated by additional experiments and the findings will be verified by application to a demonstrator geometry.
