Symposium Description:

This symposium invites abstract submission on topics related to improving our understanding of the influence of boundaries in materials. Boundaries in materials can be separated into various categories: grain boundaries, twinning boundaries, phase transformations, ferroelectric domain walls, and magnetic domain boundaries. The character of these boundaries in materials determines their overall physical properties, e.g. stiffness, strength, plasticity, dielectric constant, piezoelectric constant, coercive field, and magnetic susceptibility. Moreover, the mobility of such boundaries influences their evolution over time, which results in changes in the aforementioned properties. Understanding the influence of boundaries in materials is important in many technological applications including structural materials, electronic materials, and magnetic devices. Welcome topics include (but are not limited to) the following categories: modeling grain boundary anisotropy of energy and mobility in metals and ceramics; computational modeling of grain boundaries in microstructure (using, e.g., atomistic, dislocation dynamics, or phase field methods); characterization of grain boundary evolution during high temperature processes such as sintering;  interactions of boundaries with defects; modeling domain walls in ferroelectrics (via phase field methods, continuum mechanics, atomistics, etc.);  understanding the evolution of magnetic domains (via phase field methods, continuum mechanics, etc.).
