· HfAlNi2

HfAlNi2 is a ternary intermetallic compound combining hafnium, aluminum, and nickel, representing a high-performance metallic system studied for structural and functional applications requiring elevated-temperature stability and mechanical resilience. This material belongs to the family of refractory metal intermetallics and is primarily investigated in research and development contexts for aerospace, power generation, and high-temperature engineering environments where conventional superalloys reach their performance limits. The hafnium-aluminum-nickel system is valued for its potential to combine the oxidation resistance of aluminum-bearing phases with the structural integrity of nickel-base matrices, along with hafnium's contribution to refractory strength and creep resistance.
