Mesoscale microstructure is the hierarchical architectures of structural, chemical, electric polarization, charge, and magnetic domains that bridge the atomic scale electronic structure and the macroscopic continuum. It is the evolution of the mesoscale architecture that largely controls the responses or performances of a material and/or structure to external mechanical, electric and electrochemical stimuli. Phase-field modeling refers to a particular mathematical description of a system in which the fundamental idea is to describe the material interfaces by a smoothly changing phase field describes, that is, a diffuse-interface model. It enables that phase-field method is advantageous in addressing the time-dependent evolving morphologies process, which is hard to implement in traditional sharp-interface model. Phase-field method has been applied to a vast range of phenomena in materials processes, e.g., solidification, solid-state phase transformation, recrystallization, grain growth, and coherent precipitation, ferroelectric domain formation, particle coarsening defects evolution, etc. This mini-symposium’s main focus is to bring together the recent advances in phase-field model of microstructural evolution. We welcome abstracts on new phase-field models, new numerical methods for solving phase-field models, and also their novel applications.
