New Monte Carlo Potts Model in Metal Recrystallization Simulation

A novel recrystallization simulation 2-dimension Monte Carlo Potts model is constructed,including some reform measures such as the new nucleation pattern,the storage energy distribution,and the new node tropism switch probability formula based on the metal recrystallization physical theory and experiments.And then this novel model is applied to simulating the isothermal annealing of cold rolling high purity aluminum plate.The results show that the innovational model could emulate heterogeneous nucleating and new grain growing effectually;the simulation nucleation sequence and nucleation rate accords with that of recrystallization theory and experiments,and recrystallization kinetics curve also accords with JAMK theory.The Avrami exponent nav is less than the theoretically predicted value 2,which accords with that of experiments.
