Symposium U—Microstructure Evolution and Mechanical Properties in Interface-Dominated Metallic Materials

Interface-dominated materials are composites whose properties are largely determined by the high area per unit volume of internal heterophase interfaces and/or grain boundaries that they contain. Many nanostructured metals, such as layered composites with nano-scale layer thicknesses or polycrystals with nano-scale grains, are interface-dominated materials. Their microstructural stability and mechanical behavior are determined by interface properties. Consequently, their mechanical response, thermal stability, and degradation resistance may be improved by controlling interface crystallographic characters, chemical compositions, and internal structures. However, a complete understanding of the mechanisms relating solid-state interfaces to microstructure evolution and mechanical properties in interface-dominated materials remains elusive.

This symposium will focus on the fundamental properties of solid-state interfaces in metals, including grain boundaries and heterophase interfaces. The role of interface properties in determining the behavior of metallic interface-dominated materials will be addressed. The symposium will emphasize simulations that bridge length and time-scales as well as corresponding experiments.

Contributions on free surfaces and solid-liquid interfaces will not be considered in this symposium.

Topics will include:

  • Atomistic simulations of solid-state interfaces and grain boundaries
  • Discrete dislocation dynamics at solid-state interfaces and grain boundaries
  • Mesoscale and phase field modeling for diffusive and displacive solid-state transitions
  • Continuum modelling of solid-state interface and grain boundaries
  • Structure and energy of solid-state interfaces and grain boundaries
  • Defect-interface interactions in metals
  • Solid-state interface motion and interface mediated deformation from the nanoscale to the macroscale
  • Solid-state interface diffusion in metals
  • Role of interfaces in nanostructured metallic materials
  • Solid-state interface engineering
