Abstract Based on a current non-equilibrium dendrite growth model and a local non-equilibrium solute trapping model for dilute alloys, a model for rapid dendritic solidification of dilute alloys was developed. In the present work, we considered the results of the non-equilibrium dendrite growth model for solidification of dilute undercooled melts with different concentrations in order to reveal the concentration effect. Incorporating the fluid flow effect, we applied an extended chemical superheating model to predict the dendrite remelting of dilute undercooled melts. This model predicted that the dendrite remelting will disappear abruptly once the dendrite growth velocity exceeded the solute diffusion velocity in the liquid phase at the interface.
