BeFe4Re
metal· JVASP-64960· BeFe4Re
BeFe4Re is an experimental intermetallic compound combining beryllium, iron, and rhenium. This material belongs to the rare-earth-containing refractory metal family, which is primarily investigated in research contexts for extreme-temperature and high-performance applications. The addition of rhenium to iron-beryllium systems typically aims to enhance creep resistance and thermal stability, making it of interest for aerospace propulsion and advanced energy systems where conventional superalloys reach their performance limits.
