· JVASP-20305· DyAl

DyAl is an intermetallic compound combining dysprosium (a rare-earth element) with aluminum, belonging to the family of rare-earth aluminum intermetallics. This material is primarily of research and specialized industrial interest, valued for applications requiring the unique combination of rare-earth magnetic or thermal properties with aluminum's light weight and workability. The dysprosium-aluminum system is investigated for high-temperature structural applications, permanent magnet alloys, and advanced aerospace or defense systems where rare-earth functionality must be integrated into aluminum-based matrices.
