The free dendrite growth of iron–0.5mass% carbon 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 determined at different degrees of undercooling, and then the stability parameter for the alloy is estimated. The dendrite growth velocities obtained by phase-field simulations are compared with those obtained using the LKT model with the stability parameter of 0.05. The two are in good agreement and the validity of the LKT model is discussed with regard to practical applications.
