Fast crystal growth: Nonisothermal phase field predictions versus molecular dynamics data

Abstract

Classic kinetic theories for crystal growth and melting, such as diffusion- or collision-limited theories, encounter challenges in quantitative describing the interface velocity at large values of the driving force. One possible solution of such a crisis of classic theories is seen in using the kinetic phase field model (KPFM) formulated for small and large driving forces on solidification, melting and evaporation. The predictions of the nonisothermal phase field model are discussed in the present work to describe the nonlinear behavior of the nickel crystal growth obtained in molecular dynamic (MD) simulation.
