Microstructures with phase transitions
In this research area, we aim at establishing modelling and simulation methods for transport mechanisms inherently coupled to phase transformations in solid state bodies and liquids. The methodical approaches under concern refer to different length scales: atomistic approaches on the microscale, phase field formulations on the mesoscale, and continuum models on the meso- and macroscale. Modelling focuses on the interaction between diffusion processes and phase transformations; the development of this interaction is influenced the mechanical properties of the respective material while at the same time influencing them. The material properties are mainly determined by the microstructure under consideration on different modelling levels, the development of which is decisive. The method-orientation enables to transfer the developed modelling approaches and algorithms to different applications and classes of materials.
