| Abstract Scope |
Understanding the interfacial chemical, morphological, and structural evolution of alloys in molten salts is critical for advancing next-generation energy systems such as molten salt reactors. This work applies a multimodal characterization approach, combining in situ synchrotron X-ray imaging, spectroscopy, diffraction, and electron microscopy, to investigate how temperature and salt chemistry influence kinetic processes at metal–salt interfaces. Model systems including Ni, Cr, and Ni–20Cr in chloride-based eutectic salts, with and without metal ion additives, are used to probe the interplay between interfacial reactions, charge transfer, and mass transport in both solid and liquid phases. The study reveals how local chemical environments and thermal conditions shape morphological and compositional evolution through mechanisms such as surface diffusion and dissolution. These findings deepen our understanding of interface-driven transformations and provide insights for predictive control of material behavior in molten salt environments relevant to energy applications. |
