| Abstract Scope |
To be closer to the physical mechanism of recrystallization nucleation and to simulate the grain topological deformation in DRX more accurately, the recrystallization nucleation module and grain topological deformation technology in the existing CA model are updated and improved. This paper proposes a new idea of improving CA model by introducing the concept of multilevel cellular space into the CA simulation framework. Furthermore, rules of cell state transition and data transfer between different levels of cellular space are formulated, and multilevel cellular automaton (MCA) model including multilevel recrystallization nucleation module and full field multilevel grain topological deformation module is constructed. Finally, the MCA model is used for DRX simulation of 316LN, and simulation results are compared with experimental results to verify the validity and accuracy of the model. In addition, the influence of simulation parameters on simulation results is discussed. |
