Dr Kaoumi’s research interests are in developing a mechanistic understanding of microstructure-property relationships, with an emphasis on microstructure evolution under harsh environment (i.e. irradiation, high temperature, and mechanical stress) and how it can impact macroscopic properties and performance. Materials of interest include metallic systems such as nanocrystalline and nanostructured metallic systems, advanced alloys for structural and cladding applications in advanced nuclear systems (Austenitic steels , Advanced Ferritic/Martensitic Steels, Nanostructured Oxide-Dispersion-Strengthened (ODS) Steels), and High-temperature Ni-based alloys. 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. Characterization techniques of predilection include In-situ irradiation in TEM (over 12 years of experience), In-situ straining in a TEM, XRD, Synchrotron XRD, SEM.
