| Abstract: | The dendrite growth in the undercooled melt of pure Aluminum is simulated by the phase-field method.The influence of nucleus radius and interfacial thickness on dendrite growth of prue aluminum is investigated.The computed results are compared with the experiment and the published results.The simulation result indicated that the phase-field method was compared with the physics mechanics. |
