Virtual material development requires a broad field of competence in the area of metallurgy. Which microstructural constituents cause which final physical properties? What are the mechanisms that lead to the formation of certain metallurgical phases? How can a retained austenite in a bainite be imagined in a simplified and computer-accessible way? What does a lamellar spacing do to a pearlite? These questions and mathematical answers describe new materials.
Every metallurgical structure is the result of a physical manufacturing process. To describe this process - the sequence of heating and cooling operations, of deformation operations and rest periods - is the second task of virtual material development. Every physical process can be reported by virtually describing heat transfer conditions, material transports, chemical surface processes and much more.
The third point of virtual material development is the simulation of the material application. Finally yet importantly, the virtual crash test of each new component or vehicle. In order to be able to map the deformation behavior of the material sufficiently accurately in the FE (finite element) simulation, defined parameters must be transferred to a numerical calculation model. The parameters are determined by complex tests on the material. The large number of continuously developed steel alloys means that the material tests for model calibration are becoming a decisive time and cost factor, so that both steel manufacturers and the automotive industry are endeavoring to find an improvement or acceleration of the parameter determination in this respect. Here we are ready to offer faster results.
