| Abstract Scope |
Zirconium alloys are used in the nuclear industry due to their low neutron capture cross-section and resistance to corrosion, irradiation and creep. The microstructure of the nuclear fuel components evolves during the manufacturing route which can impact the subsequent processes or the final properties. Numerical modeling of thermo-mechanical processes with FORGE software is applied to better understand these microstructural evolutions. These models provide the thermo-mechanical history of the material, which is then used to assess the continuous dynamic and post-dynamic recrystallization during hot forming and the static recrystallization during heat treatments.
Mean-field models were integrated into FORGE1 software, to obtain the microstructure evolution at the macro-scale of the component. Full-field models (DIGIMU1 software) was developed to assess some microstructural heterogeneities and the influence of initial microstructure at the micro-scale. These two recrystallization models provide complementary information to optimize the process parameters at the macro-scale and to better understand micro-scale phenomena. |
