| Abstract Scope |
The ordering of irradiation-induced bubbles and voids leads to the formation of three-dimensional superlattices, an effective mechanism for gas storage. Defect superlattices have been reported in a variety of materials systems under irradiation, however, their formation mechanisms remain controversial. In this presentation, we will summarize our recent research progress on the understanding of bubble and void superlattice formation in fcc and bcc metals under irradiation. The role of materials’ anisotropic diffusion on the formation of defect superlattices is studied using advanced experimental and modeling tools. Understanding the mechanisms that govern the defect self-organization is essential for predicting the lifetime of materials in irradiation environments. |
