Ta3Fe8Si
metal· JVASP-121857· Ta3Fe8Si
Ta₃Fe₈Si is an intermetallic compound combining tantalum, iron, and silicon, belonging to the family of refractory metal silicides and intermetallics. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in high-temperature structural applications where the combined properties of tantalum's refractory character and iron's structural stability could be leveraged. The tantalum-iron-silicon system is investigated for aerospace and ultra-high-temperature environments where conventional superalloys reach their thermal limits.
