摘要: A linear morphological stability of the solid-liquid interface is analyzed for a binary alloy in limit low and high crystal growth velocities. Using result this analysis, diagram morphologies derived whole range solidification rates with indicating critical velocities transitions planar front ⇔ cellular/dendritic structure. It specially noted that speed solute diffusion bulk liquid limits absolute chemical velocity from high-rate transition cells/dendrites ⇒ front.
