| Abstract Scope |
Coupled Kinetic Monte Carlo (KMC) Potts Model and finite element method (FEM) simulations were implemented to investigate the impact of as-cast and homogenized monolithic U-10Mo foil microstructure on the emergent microstructure after rolling and reheating. The effects of grain size distribution, uranium carbide (UC) distribution, rolling parameters, and texture on recrystallization were considered. This study established that grain structure and rolling reduction have the strongest influence on recrystallization kinetics and the fabricated grain structure. Over multiple passes of hot rolling, grain refinement accelerated with increased rolling reduction. Rolling reduction accelerated recrystallization more in coarse grain structures than in fine grain structures. The UC distribution weakly impacted this behavior. Particle stimulated nucleation (PSN) increased with grain size, but minimally affected recrystallization kinetics and grain structure. Low-angle grain boundaries in U-10Mo increased with grain size, but decreased with rolling reduction. Simulations established the thermomechanical treatment required to fully refine the foil microstructure. |
