Dr Kaoumi’s research interests are in the field of nuclear materials, especially metallic systems, with a special focus on (but not limited to) nanocrystalline and nanostructured metallic systems, advanced alloys for structural and cladding applications in advanced nuclear systems such as Austenitic steels , Advanced Ferritic/Martensitic Steels, Nanostructured Oxide-Dispersion-Strengthened (ODS) Steels, and High-temperature Ni-based alloys. The goal is to develop a mechanistic understanding of microstructure-property relationships in advanced alloys, with an emphasis on the microstructure evolution under harsh environment (i.e. irradiation, high temperature, and mechanical constraint) and how it can impact macroscopic properties and performance. By understanding the basic mechanisms of degradation of materials at the nanostructure level, it will be possible to predict the materials performance and to design for better alloys. Techniques of interest include Electron Microscopy, XRD, Synchrotron XRD experiments, In-situ irradiation in TEM, In-situ straining in TEM.
