· JVASP-36424· TbAl

TbAl is an intermetallic compound combining terbium (a rare-earth element) with aluminum, forming a binary metallic phase used primarily in research and specialized high-performance applications. This material belongs to the rare-earth intermetallic family and is of interest for its potential combination of lightweight aluminum with the magnetic and thermal properties characteristic of terbium. TbAl and related rare-earth aluminum compounds are explored in magnetocaloric applications, advanced permanent magnets, and high-temperature structural systems where rare-earth strengthening and magnetic functionality are simultaneously required.
