Abstract Scope |
A simulation model of recrystallization and grain growth has been developed to investigate grain structure evolution during deformation and heat treatment in polycrystalline UMo fuel. SEM images of microstructures were directly used as input for closed loop simulations of multiple rolling and annealing passes. FEM calculations of deformation and Potts Model simulations of recrystallization and grain growth were used iteratively to inform each subsequent stage of simulation. The model was then applied to predict the grain structure evolution during multiple-pass hot rolling of U-10Mo, and benchmarked against experimentally observed U-10Mo recrystallization behavior. The results showed that our model is able to capture the coupling between deformation and recrystallization, and quantitatively reproduce the observed U-10Mo recrystallization and grain growth kinetics with respect to time and temperature. A separate model of post-recrystallization U-10Mo grain growth is also discussed. |
