· JVASP-21649· LuAl8Fe4

LuAl8Fe4 is an intermetallic compound combining lutetium, aluminum, and iron—a rare-earth metal system typically studied for structural applications requiring high strength-to-weight performance. This material belongs to the family of rare-earth aluminum intermetallics, which are of primary interest in research and materials development rather than widespread industrial production; such compounds are investigated for potential use in high-temperature aerospace and defense applications where conventional alloys reach performance limits.
