· JVASP-51115· CoReGe2

CoReGe2 is an intermetallic compound combining cobalt, rhenium, and germanium, representing an experimental high-performance material from the refractory intermetallic family. This compound is primarily of research interest for extreme-environment applications where conventional alloys reach their performance limits, with potential use in aerospace propulsion, high-temperature structural applications, and advanced electronics where the combination of metallic bonding and intermetallic ordering can provide superior strength retention and thermal stability compared to traditional superalloys or refractory metals.
