· HfGaNi2

HfGaNi₂ is an intermetallic compound combining hafnium, gallium, and nickel, representing a research-phase material in the high-entropy and refractory intermetallic family. This ternary system is primarily of scientific interest for exploring advanced structural materials that combine the high-temperature stability of hafnium-based systems with the mechanical properties potentially offered by nickel intermetallics. Applications remain largely experimental, with potential relevance to extreme-environment aerospace components, high-temperature structural applications, or thermal barrier systems where conventional superalloys reach their limits.
