| Popis: | The free dendrite growth of aluminum-4.5 mass%copper alloy has been investigated using a three-dimensional phase-field model with thin-interface-limit parameters. The dendrite growth velocity and the tip radius of curvature are measured for a given value of anisotropy intensity of the interface energy, and the stability parameters are determined at different degrees of undercooling. The dendrite growth velocities are compared with those obtained by LKT (Lipton, Kurz and Trivedi) model, and the role of the stability parameter is quantitatively discussed. |
