Abstract

Based on the three-dimensional phase field model, the competitive growth of columnar crystals under the conditions of different anisotropies and different subcooling degrees in the directional solidification process was simulated with the Al-2%mole-Cu two element alloy as an example. The influence of anisotropy and supercooling on the columnar crystal competition growth was studied. The simulation results showed that with the increase of anisotropy, the growth degree of non preferred dendrites increased first and then decreased; with the increase of supercooling, the morphology of preferred dendrites increased, and two dendrites appeared on the primary dendrite, but the change of non preferred dendrite morphology was not obvious.
