Dynamics of Structural Phase Transformations Using Molecular Dynamics

摘要

This project studied the dynamic response of metallic materials due to twinning and microstructural evolution. We have studied -- using molecular dynamics -- the nucleation of twinning interfaces, the transition to motion of a static twin interface, the steady kinetics of twinning interfaces. Finally, we have formulated a new continuum multiscale phase-field model that enables us to incorporate prescribed nucleation behavior and complex kinetics.
