Symposium 1: Characterization and Modeling of Ceramic Interfaces: Structure, Bonding, and Grain Growth

The evolution of ceramic microstructures, including densification and grain growth, is controlled by the formation of interfaces and grain boundaries. The grain boundary core structure, interatomic bonding behavior, and potential segregation to the interface plane can be controlled by suitable processing conditions and strongly affect grain growth behavior. An in-depth mechanistic understanding based on thermodynamic stability and kinetic phenomena at grain boundaries is required to tailor overall microstructures in polycrystalline ceramics. Recent progress in atomic resolution and in situ characterization as well as modeling enables us to gain a fundamental mechanistic understanding of grain boundary formation and grain growth. This symposium will focus on new phenomenological findings that emerged from advanced characterization and modeling efforts of grain boundary and interface structures. Special emphasis will be placed on the impact of atomic and electronic interface structures on microstructure evolution and grain growth phenomena.
