Special Session 4
INTERFACES IN CRYSTALLINE MATERIALS: STRUCTURE, THERMODYNAMICS, KINETICS, AND ALLOYING EFFECTS (SS4)

Understanding the chemistry, diffusion, electronic properties and dynamics of interfaces is central to controlling and predicting the engineering and functional properties of materials. Recent advances in characterization techniques and computational modeling have enabled a detailed examination of interfacial structural, electronic and chemical states and their impact on microstructure formation and evolution. This symposium aims to bring together experimentalists and computational researchers whose work focuses on the fundamental science of interfaces in materials. Different classes of interfaces will be of interest with a special focus on grain boundaries and crystalline interphase boundaries.


TOPICS:

• Interfacial motion including grain evolution and phase transformations.
• Compositional effects, including segregation and the impact of alloying on interface energy and diffusion processes.
• Interface structure and chemistry in multi-component systems, including high entropy materials and oxides.
• Mechanisms of interfacial diffusion and transformations in extreme environments (including irradiation, temperature, and stress).
• Approaches to engineering interfacial properties, linking fundamentals of interfacial structure and chemistry, materials processing, and engineering behavior.
• Correlation of electronic properties of interfaces and ionic diffusion, electrical conductivity or thermal transport.
