· JVASP-15521· YCo2Si2

YCo2Si2 is an intermetallic compound combining yttrium, cobalt, and silicon, belonging to the rare-earth transition metal silicide family. This material is primarily of research and development interest for high-temperature structural applications, where its combination of metallic bonding and intermetallic ordering offers potential advantages in stiffness and thermal stability. While not yet widely deployed in production, YCo2Si2 and related rare-earth silicides are being explored for aerospace, energy, and electronic device applications where conventional superalloys reach their performance limits.
