· JVASP-9422· ErAl8Fe4

ErAl8Fe4 is an erbium-aluminum-iron intermetallic compound, representing a rare-earth metal alloy system that combines erbium's nuclear and thermal properties with aluminum and iron for structural compatibility. This material belongs to the family of rare-earth intermetallics and appears to be primarily a research or specialized industrial compound rather than a commodity alloy. Its application is likely driven by niche requirements in nuclear engineering, high-temperature aerospace components, or advanced materials research where rare-earth additions provide benefits in neutron absorption, creep resistance, or phase stability.
