| Abstract Scope |
The investigation of nanostructured materials (NSMs) has revealed numerous favorable properties arising from their unique nano- and microstructure, primarily attributed to the large fraction of interfaces. For example, enhancements in strength and radiation resistance have been observed. Comprehensive understanding of these property modifications necessitates the examination of defect interactions, such as dislocations and point defects with interfaces. However, utilization of NSMs in extreme environments also gives rise to undesirable effects such as coarsening and phase transformations. To address this inherent instability, alloying concepts have been pursued, including the emergence of chemically complex materials (CCMs), and the combination of chemical and microstructural complexity. In this talk, we will present a detailed analysis of the nano- and microstructure of various NSMs, highlighting their resulting properties with an emphasis on mechanical performance and radiation resistance. Furthermore, we will discuss the characterization techniques employed to elucidate the atomic-scale details of the nano- and microstructure. |
