Ta4BeV
metal· JVASP-65059· Ta4BeV
Ta4BeV is a refractory metal intermetallic compound combining tantalum, beryllium, and vanadium. This is an experimental or research-phase material; it belongs to the family of high-melting-point intermetallics explored for extreme-temperature structural applications where conventional superalloys reach their limits. The tantalum-beryllium base suggests potential for aerospace or nuclear thermal environments, though practical engineering adoption remains limited due to the challenging metallurgy of beryllium and the scarcity and cost of tantalum.
