· JVASP-39721· YbHfRh2

YbHfRh2 is an intermetallic ceramic compound combining ytterbium, hafnium, and rhodium, representing an experimental high-entropy or complex intermetallic material system. This compound belongs to the emerging class of refractory intermetallics under research for extreme-temperature and high-stress applications where conventional superalloys reach their limits. While not yet in widespread industrial production, materials in this family are being investigated for next-generation aerospace propulsion systems, nuclear reactors, and advanced thermal-barrier coatings where thermal stability, oxidation resistance, and mechanical strength at elevated temperatures are critical.
