In this group a numerical tool for multi-criteria optimization is developed. In particular, it is applied on the alloy development of nickel-based superalloys. The scientific research focuses on probabilistic and deterministic models to find all optimum solutions (pareto front) in the search space. By the development of the CALPHAD method in the recent decades, new opportunities to extend the classical alloy development by means of the prediction of physical properties and microstructure arose. Most property models base on thermodynamic and kinetic calculations, which are coupled by the TC API to the commercial software ThermoCalc and DICTRA.
The research is funded by the collaborative research center SFB Transregio 103 (http://www.sfb-transregio103.de/).
