· JVASP-82008· HfScAu2

HfScAu2 is a ternary intermetallic compound combining hafnium, scandium, and gold—a research-phase material rather than an established commercial alloy. This composition falls within the broader class of high-entropy and lightweight intermetallics being explored for extreme-environment applications where conventional alloys reach their limits. The material's low density combined with the refractory properties of hafnium suggests potential for high-temperature structural use, though engineering adoption remains limited pending further characterization of mechanical properties, processability, and cost-benefit analysis against competing alternatives.
