An Integrated Simulation of Multiple-Pass U-10Mo Alloy Hot Rolling and Static Recrystallization

Abstract To achieve a desired microstructure and minimize the thickness variation in rolled foils, researchers must understand effects of foil fabrication process variables on evolution. We developed an integrated simulation deformation recrystallization that employs finite element method (FEM) kinetic Monte Carlo (KMC) Potts model, respectively, to investigate evolution during multiple-pass hot rolling heat treatment polycrystalline U-10Mo fuel. Scanning electron microscopy backscatter diffraction images microstructures were directly used as input FEM calculation deformation, calculated strains determine driving force nucleation growth recrystallized grains model. Grain structures predicted by model update grain structure material properties for FEM. Simulation alternated between simulate multiple treatments. The initial parameters determined benchmarking kinetics against experimental data. Then, was applied predict Results showed our can capture coupling quantitatively reproduce observed kinetics. results demonstrated function parameters.
