Symposium MD8—Multiscale Behavior of Materials in Extreme Environments

Fundamental understanding of materials behavior at multiple length and timescales requires a seamless integration of simulation tools for defect evolution with characterizations and experiments. Modern fabrication approaches aim at improved material performance by optimizing microstructures. However, in extreme environments, these microstructures may evolve, degrading their pristine performance. Characterization and experimental techniques and protocols explore and characterize evolving material structures while multiscale theory, modeling, and simulation probe governing mechanisms of structural evolution.

This symposium will focus on the intersection of advanced characterization techniques, modeling, and simulation tools that inform the development of capabilities to predict and tailor materials behavior in extreme environments at the nano-, meso-, and microstructure scales. The characteristic complex microstructures that occur in these systems may be due to a variety of factors such as strain, compositional differences, chemistry, crystallography, growth kinetics, etc. It is crucial to understand the impact of these mechanisms that govern self-organization at different length scales, and their interplay with competing effects, such as internal or external fluctuations, that tend to modify the structural order. The ultimate goal is to tailor advanced materials through predictive design where controlled structures and microstructures are desirable to achieve properties and functionality that improve performance, reduce risk of product failure, increase lifespan, and minimize environmental impact.

Researchers that emphasize fundamental understanding of unit processes governing materials stability in extreme environments are encouraged to submit abstracts. Of specific interest are contributions that combine experimental discovery with modeling and simulation to develop predictive models of material behavior in harsh environments.

Topics will include:

  • Underlying mechanisms of pattern formation at the nano-, meso-, and submicron scales driven by stress and radiation damage.
  • Phase transformations under high temperature, pressure, high heat flux, or radiation.
  • Mesoscale dislocation substructure evolution under quasistatic strain and radiation.
  • Behavior of nuclear reactor core materials, inert matrices, waste forms, and transmutation targets.
  • Fundamental mechanisms of material degradation under corrosive (molten salt, lead, aqueous) environments.
  • A tutorial complementing this symposium is tentatively planned.
