Abstract Scope |
Rare earth elements possess unique electronic, magnetic, and thermal properties, making them valuable for advanced technologies. However they remain underexplored due to the limited phase equilibrium data. Cerium, the most abundant rare earth, exhibits promising high-temperature characteristics suitable for structural and functional applications. Nickel and Chromium, well-established for high-temperature performance, form the basis of many superalloys. The Ce-Cr-Ni system is of particular interest, especially in nuclear reactors where rare earths like Ce are generated during nuclear reactions. They interact with Ni-Cr-Fe-based cladding materials forming intermetallics that are detrimental to reactor performance. Understanding phase equilibria in the Ce-Cr-Ni system is thus critical for predicting material behaviour under reactor conditions and improving cladding alloys. This study aims to address this data gap and explore the phase relations within the Ni-Cr-Ce system using Vacuum Arc Melting , long-term heat treatment and characterization techniques such as XRD, SEM-EDS , EPMA etc. |
