MICRESS® is a unique tool for microstructure simulation developed by Access. It allows the calculation of the microstructure evolution during casting and further heat treatments on a sound physical and thermodynamic basis for technical multicomponent and multiphase alloys. Scale bridging to the process level is an active research topic together with different partners in academia and industry, e.g. in the framework of the “cluster of excellence: Integrative production technology in high wage countries” hosted at the RWTH Aachen University.
