Hf2Al3Au
metal· JVASP-109738· Hf2Al3Au
Hf2Al3Au is an intermetallic compound combining hafnium, aluminum, and gold in a defined stoichiometric ratio. This is a research-phase material studied for its potential in high-temperature structural applications and specialized alloy development, belonging to the broader family of refractory intermetallics that leverage hafnium's exceptional heat resistance. The inclusion of gold suggests investigation into thermal stability, oxidation resistance, or electronic properties in extreme environments where conventional nickel- or cobalt-based superalloys reach their limits.
