Symposium description

The ideal conditions of perfect order or disorder give rise to narrow ranges of materials properties. Between these extreme cases, materials properties exhibit a significant variability due to the presence of defects and microstructure features. The science of defects and microstructure in materials has been largely established during the past century; it includes a wide range of elegant theories and experimental techniques developed to tackle problems related to materials defects and microstructure. At present, however, our understanding of defects and microstructure is still far from complete. This is mainly due to the complexity inherent in the collective dynamics of defects and the associated fact that the formation and evolution of microstructures in materials need to be considered as emergent phenomena where the dynamics and interactions of many defects give rise to novel features that cannot be straightforwardly be traced back to single defect properties.

The Microstructure Complexity and Self-Organization in Materials symposium will bring together materials researchers to address a number of fundamental questions related to predictability of collective defects behavior and microstructure evolution in materials, including self-organization of defects and microstructures. These dynamical aspects of materials behavior take place under driving forces of mechanical, chemical and thermal nature and play a critical role in materials synthesis and performance. The theme of this symposium has a mixed theoretical, computational modeling and experimental flavor. As such, the symposium organizers will target a mixed community, including specialists in mesoscale material modeling, computational mechanics researchers and key experimentalists.

Specific topics of interest include, but are not limited to:

  • Complexity, order and self-organization in materials
  • Statistical and geometrical description of heterogeneity in materials
  • Quenched-in heterogeneity and disordered materials
  • Thermodynamics and kinetics of microstructures
  • Plasticity of solids, dislocation patterns
  • Compositional, microstructure and morphological patterns in driven materials
  • Interactions between phase and defect microstructure evolution
  • Mesoscale characterization of materials
  • Microstructure mechanics and stress engineering in micro-structured systems
  • Mesoscale simulations methods (MC, DDD, Phase field, etc.)
