This paper describes the Monte Carlo simulation of grain growth in two-dimensional matrix.The simulation is carry out in two-dimensional matrix with 300×300 hexagonal lattices in order to obtain the grain growth kinetics and topological evolution.The grain growth dynamics constant is calculated to be n=0.48.The simulated result shows the application of Monte Carlo techniques in the evolution of microstructure.The characteristic of Monte Carlo method is investigated philosophically.The self-contradiction of simplicity and complexity is dealt with presenting the whole evolution effect from start of locol rule.The application of MC on the simulation of material processing is described.
