ScBeW2
metal· JVASP-67798· ScBeW2
ScBeW2 is a refractory metal intermetallic compound combining scandium, beryllium, and tungsten, representing an experimental materials system rather than a commercial alloy. This composition belongs to the family of high-melting-point intermetallics under research investigation for extreme-environment applications where conventional superalloys reach their thermal limits. The material's potential lies in aerospace and high-temperature structural applications, though limited industrial adoption reflects its current research status and challenges related to beryllium toxicity, machinability, and cost.
