· JVASP-22756· HoAl7Au3

HoAl7Au3 is an intermetallic compound combining holmium, aluminum, and gold, belonging to the rare-earth metal alloy family. This is a research-stage material studied for its potential in high-performance applications where rare-earth strengthening and gold's chemical stability could provide advantages in extreme environments or specialized electronic/thermal systems. The material represents exploratory work in ternary intermetallic design rather than an established commercial alloy.
