Cross-sectional helium irradiation reveals interface-controlled bubble evolution in Cr/CrAlSiN multilayer coatings on zirconium alloys
Renda Wang, Xue Bai, Xueliang Pei +9
The irradiation stability of Cr based protective coatings on zirconium alloys is critical for the development of accident-tolerant fuel claddings. However, conventional surface irr…
Defect Landscape Engineering Suppresses Helium Damage in Ceramics
Nabil Daghbouj, Ahmed Tamer AlMotasem, Bingsheng Li +12
Helium accumulation in structural ceramics used in nuclear, fusion, and aerospace systems causes swelling, cracking, and early failure, yet controlling this damage has remained elu…
Asymmetrical Defect Sink Behaviour of HCP/BCC Zr/Nb Multilayer Interfaces: Bubble-Denuded Zones at Nb Layers
Nabil. Daghbouj, H. S. Sen, Mohamed BenSalem +11
Radiation induced helium bubble formation poses a major challenge to the structural integrity of materials in nuclear energy systems. In this study, we investigate defect evolution…
A comparative nanotribological investigation on amorphous and polycrystalline forms of MoS2
Hesam Khaksar, Prashant Mittal, Nabil Daghbouj +3
The wear behavior of two amorphous and polycrystalline forms of MoS2 prepared by magnetron sputtering has been characterized in a combined nanoindentation and atomic force microsco…
