· JVASP-100837· Fe3Si4Ir

Fe3Si4Ir is an intermetallic compound combining iron, silicon, and iridium. This is an experimental research material rather than a commercially established alloy; it belongs to the family of high-entropy and refractory intermetallics being investigated for extreme-environment applications where conventional superalloys reach their limits.
