Abstract
Phase-field method has become the primary computational technique connecting atomistic calculations and macroscopic continuum method. It is a density-based approach at the mesoscale for modeling and predicting the temporal microstructure and property evolution in materials undergoing nonequilibrium processes. The presentation will give a brief introduction to the phasefield method and its various applications to modeling temporal evolution of microstructures, including the recent applications to mesoscale structural evolution involving both electronic and structural phase transitions as well as the dynamics of mesoscale structure evolution. The emphasis is on employing the phase-field method to provide guidance to designing materials for optimum properties or discovering novel mesoscale phenomena or new materials functionalities.
