Abstract Scope |
A developed and validated coupling of Kinetic Monte Carlo (KMC) Potts Model and finite element method (FEM) simulations was implemented in order to investigate the impact of microstructural features in as-cast and homogenized monolithic U-10Mo foils on the emergent microstructure after rolling and reheating treatments. Grain size distribution, uranium carbide (UC) size distribution, UC volume fraction, the spatial distribution of UC, and rolling reduction magnitude were considered parameters that could potentially affect recrystallization behavior of the rolled U-10Mo foils. This simulation study established that grain structure and the magnitude of rolling reduction have the strongest influence on recrystallization kinetics and the fabricated grain size distribution. The UC distribution had only a weak impact on the recrystallization kinetics and final microstructures. While particle stimulated nucleation (PSN) occurred in simulation with increasing frequency as grain size increased, its incidence did not appear to considerably affect the recrystallization kinetics or grain size distribution. |
