· JVASP-106249· Hf3Al

Hf3Al is an intermetallic compound in the hafnium-aluminum system, representing a high-melting-point metallic material combining hafnium's refractory properties with aluminum's lightweight character. This material is primarily of research and development interest for ultra-high-temperature applications where exceptional thermal stability and oxidation resistance are required, particularly in aerospace and advanced energy systems where conventional superalloys reach their performance limits.
