Abstract The Monte Carlo simulation method for crystal growth is explored by including the macroscopic temperature, solute redistribution within the liquid phase and the thermodynamics in metal solidification process. A model coupling macro and micro is created to describe solidification structure formation in solidification process. The Al-4.5%Cu (mass fraction) alloy is used in the simulation. Finally, the simulation results are compared to experimental results. It shows that this simulation method is feasible.

Key words: Monte-Carlo method modeling of heterogeneous nucleation and growth free energy undercooling
