Join us for Dr. Long-Qing Chen’s talk on Wednesday, March 27th at 3pm in Maryland Hall room 110!
ABstract: Thermodynamic Basis and Applications of Phase-field Method
Phase-field method is a density-based computational method at the mesoscale for modeling and predicting the temporal microstructure and property evolution during materials processes. The seminar will briefly outline the thermodynamic basis of the phase-field method starting from the Gibbs’ differential form of the fundamental equation. The various applications of the phase-field method to modeling temporal evolution of the microstructures will then be briefly introduced, 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.
