Multiscale Approaches for the Evolution of Microstructure in Solidification Processes

3:30-5:30 PM
Room: Constitution

In industrial solidification processes often a specific "dendritic" microstructure is observed. It influences the properties of the material and its evolution depends on the macroscopic solidification conditions. Solidification is nowadays well understood on a macroscopic scale. The modeling of crystal growth has also seen considerable progress; models based on surface evolution, energy minimization and phase field models have been studied. A challenging subject is the coupling of microscopic and macroscopic scales. In the minisymposium, the speakers will present different models for the simulation of microstructure, crystal growth and grain structure. They will discuss possibilities of coupling the microscopic and macroscopic scales.
