Scalebridging Thermodynamic and Kinetic Simulation (STKS)

|Prof. Dr. Ingo SteinbachPhase transformations are phenomena of general importance and play a significant role in all areas of materials processing. They determine the microstructure of materials and control their macroscopic properties. The research activities in the department focus on the mesoscopic scale of heterogeneous multiphase microstructures. We apply different theoretical methods to investigate the constitutive laws controlling microstructure evolution during various stages of materials processing, ranging from solidification to solid-state transformations during thermal processing.||

|In a scale-bridging approach we incorporate first principles calculations of phase stability and transport coefficients and analyze our results with respect to macroscopic properties of condensed matter. Among numerical techniques applied within our department are first-principles methods for phase-stabilities, the CALPHAD method (CALculation of PHAse Diagrams) to calculate phase-stability, the phase-field method to describe phase transformations and microstructure evolution in crystalline materials. Last, but not least, the Lattice-Boltzmann method is applied to solve surface tension driven flow.|
The department’s activities are grouped in five areas being focused on different techniques and scales.
