metal· JVASP-60865· Hf9Mo4As
Hf9Mo4As is a hafnium-molybdenum-arsenic intermetallic compound belonging to the refractory metal alloy family. This is a research-phase material under investigation for ultra-high-temperature applications where exceptional thermal stability and hardness are required. The hafnium-molybdenum base provides intrinsic high-temperature strength, while the arsenic addition modifies the crystal structure and mechanical behavior; such ternary compositions are studied as candidates for aerospace thermal protection, advanced reactor systems, and extreme-environment structural components where conventional superalloys reach their limits.
