popup.description2
Theoretical models and algorithms based on the phase field theory in combination with the reaction rate theory have been developed for modeling the precipitation/dissolution of secondary phase precipitates, the evolution of the defect structure, and radiation growth in zirconium-based alloys with niobium and tin additions during annealing of solid solution and irradiation of the annealed sample with the study of the dynamics of radiation-stimulated segregation of impurities and the study of the mechanical and corrosion properties of these alloys using the theory of elasticity and thermodynamic approaches. Еhe features of radiation-stimulated precipitation were identified in zirconium alloys with a low concentration of impurities and the effect of irradiation conditions on the change in the mechanical properties of these alloys was investigated.
