Department of Materials Science and Engineering Spring Seminar Series: Long-Qing Chen

Description

Long-Qing Chen, a professor of materials science and engineering, of engineering science and mechanics, and of mathematics at the Pennsylvania State University, will give a talk titled "Thermodynamic Basis and Applications of Phase-Field Method" for the [Department of Materials Science and Engineering](Department of Materials Science and Engineering).

Abstract:

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.
