Coupled Phase Field/Monte Carlo Simulation for Heterogeneous Crystallization Kinetics — •Jürgen Hubert and Heike Emmerich — RWTH Aachen, Computational Materials Engineering, Center for Computational Engineering Science (CCES), Institute of Minerals Engineering (GHI), Mauerstrasse 5, 52064 Aachen*

Phase field models are a now well established and rapidly growing section within the field of modeling the evolution phase transitions. Among other things they can be used for the simulation of nano crystallization processes, grain growth and heterogeneous nucleation. By combining the phase field method with Monte Carlo Algorithms, the evolution of the crystal orientation can be described with only a slight increase in the necessary computing power.

This entry will show new expansions of existing models, as well as the possibilities and challenges of grain growth simulations with a large number of different crystal orientations.
