· JVASP-106801· Hf2Al3Ni

Hf2Al3Ni is an intermetallic compound combining hafnium, aluminum, and nickel, representing a high-temperature metallic material from the refractory alloy family. This material is primarily investigated in research contexts for aerospace and high-temperature structural applications where exceptional thermal stability and strength retention at elevated temperatures are critical. Its appeal lies in the potential to enable lighter, more durable components for extreme-temperature environments compared to conventional superalloys, though commercial deployment remains limited pending further development and characterization.
