Investigating the sink efficiencies of interfaces under irradiation
… in polycrystals. Interfaces serve as sinks, sources or trap sites for vacancies, which facilitate creep, can drive interface migration, or serve as a vacancy-interstitial recombination site that results in an ideal lattice. This latter role provides a general approach to design …

Grain-Boundary Kinetics And Nonequilibrium Grain-Boundary Structure
… model is exemplified by the study of GB sink efficiency to point defects under irradiation. It is found that the GB sink effect can be modeled by Robin or Neumann boundary condition for a continuum diffusion equation. Finally, nonequilibrium GB structure in polycrystalline thin films is …

Impact of grain boundary character on the radiation-induced segregation morphology in proton-irradiated 316L austenitic stainless steel
… depletion or enrichment of atoms at point-defect sinks such as grain boundaries and dislocation loops in metallic alloys. This segregation can be so strong that it leads to radiation-induced precipitation at these sinks. Segregation and precipitation at these microstructural features can result in …
