Abstract:

In this study,a simulation model of deformed microstructure has been proposed on the basis of the initial microstructure obtained from normal grain growth simulation with Monte Carlo method.And simulation models of recrystallization microstructure of heterogeneous and simultaneous nucleation and random growth of nuclei have been developed in terms of the mechanism of microstructure evolution.On the basis of the simulated microstructure parameters distribution obtained by incorporating the neural network model into FEM Code,simulation and visualization of the microstructure of Ti-15-3 alloy during hot compression deformation and solution treatment have been realized.Comparison of the simulated results with the corresponding experimental ones indicates that the size and distribution of the simulated grains agree well with the actual ones.These studies lay scientific foundation for determining reasonable hot forming process.
