Coupling Plasticity and Phase Transformations The central theme of this symposium focuseson the fundamental understanding of how plasticity and phase transformations interact as metals undergo deformation. Much of how defect evolution and phase transformations impact each other is unknown, yet it is known that this interaction can significantly impact the thermodynamics and kinetics of phase transformations along with the overall microstructural evolution. This symposium welcomes presentations that investigate this coupling using either or both modeling and experimental techniques at all length scales.

Topics of Interest:

  • Experimental studies investigating phase transformations and microstructural evolution
  • Atomistic, (microstructure-sensitive) continuum scale, or combined quasi-continuum models that address the coupling between phase transformation and defect evolution
  • Phase field modeling of phase transformation and/or dislocation dynamics under load paths that support phase changes
  • New theoretical techniques that simultaneously address phase changes and defect evolution
