Rapid Phase Transformation Under Local Non-Equilibrium Diffusion Conditions, Sergey Sobolev
Rapid Phase Transformation Under Local Non-Equilibrium Diffusion Conditions, Sergey Sobolev
Sergey Sobolev
Phase transformation with a moving interface occurs under far from local equilibrium conditions when the interface moves with sufficiently high velocity. This deviation cannot be adequately described by the classical irreversible thermodynamics with diffusion equation of parabolic type because it assumes local equilibrium hypothesis. The local non-equilibrium diffusion model has been developed to take into account the deviation from local equilibrium during binary alloy solidification using the hyperbolic diffusion equation. The model introduces a finite propagation velocity of concentration disturbances in the bulk liquid VD as the characteristic diffusion parameter and predicts a sharp transition from diffusion controlled to diffusionless …
