Generating 2D Non-equiaxed Initial Microstructure for Monte Carlo Simulation Using Modified Voronoi Model

摘要：

　　A modified Voronoi model is established based on the Richards method to generate 2D non-equiaxed initial microstructure for Monte Carlo simulation.Microstructures produced by the ordinary Voronoi model are isotropic and cannot reflect the effects of the deformed grain shape on the annealing process.The modified Voronoi model based on ellipse set can be used to construct the deformed microstructure.The initial microstructure reflects the mean strain and the grain size distribution follows lognormal distribution.
