Description

Honoring Bennett Larson, Corporate Fellow, Emeritus, Oak Ridge National Laboratory, and James Belak, Senior Scientist, Lawrence Livermore National Laboratory

The ideal case of materials with perfect crystalline order gives rise to only a narrow range of mechanical and physical properties. Conversely, critical to virtually all technologically important materials applications, is the wide range of new or enhanced properties introduced by the hierarchical nature of defects and microstrucure features. The science of defects and microstructure in materials has been largely established during the past century; that includes a wide range of theories and experimental techniques designed to tackle problems related to materials defects and microstructure. At present, however, our understanding for defects and microstructure is still far from complete. The Defects and Microstructure Complexity in Materials symposium brings together a broad range of materials researchers for a technical exchange and a discussion of the scientific issues driving research in this field.

The topics of interest to this symposium include, but are not limited to:
• Structure and energy of defects and microstructure in crystalline solids
• Statistical properties of defects: thermodynamics and kinetics
• Defect production and evolution in driven materials: deformation, irradiation, and extreme conditions
• Defect clustering and nucleation phenomena
• Defects and microstructure aspects of deformation and fracture
• Nonlinear dynamics of defects and pattern formation in materials
• Defects and microstructure evolution in materials synthesis and processing
• Materials properties derived from defects and microstructure information
• Novel experimental and theoretical techniques for defect and microstructure characterization

The symposium will emphasize the theoretical, computational and experimental aspects of defects and microstructures in materials manufacturing and performance. One or more joint sessions are anticipated with other symposia of overlapping scope during the finalization of the program. A special issue will be organized for publication in Materials Theory, a Springer-Nature journal.
