· Hf1 Sc1 Ir2

Hf1Sc1Ir2 is an experimental ternary intermetallic compound combining hafnium, scandium, and iridium. This material belongs to the family of refractory high-entropy and multi-principal-element alloys, currently under investigation in research settings rather than established in commercial production. The combination of these elements—particularly the incorporation of iridium with refractory metals—targets extreme-environment applications where conventional superalloys and ceramics face limitations, with potential relevance to aerospace thermal structures, advanced catalysis, or ultra-high-temperature electronic devices.
