Microstructure evolution and physical properties of polycrystalline materials are closely linked to their internal defect configurations. In ceramic grain boundaries, dislocations, point defects, and their associated charge distributions often dominate mechanical, optical, and electrical properties. This symposium aims at reviewing and highlighting the latest discoveries on fundamental aspects of grain boundary structures and thermodynamics, and related interface kinetics. A deep understanding of grain boundaries obtained from advanced characterization, multiscale modeling, and processing experiments, guides microstructure design and development of new physical properties for structural and functional ceramics.
Proposed sessions and topics of interest:
- Thermodynamic and kinetic stability of interfaces
- Microstructure evolution through sintering and grain growth
- Novel Characterization techniques (incl. in-situ, 4D-STEM)
- Interface theory and modeling, including artificial intelligence/machine learning techniques
- Fundamentals of space charge: segregation, adsorption, electronic structures
