metal· Al0.4Nb0.33Ni0.2
Al₀.₄Nb₀.₃₃Ni₀.₂ is a multi-principal-element alloy (compositionally complex alloy or high-entropy alloy precursor) combining aluminum, niobium, and nickel in near-equimolar proportions. This material exists primarily in the research domain as a candidate for high-temperature structural applications, where the combination of lightweight aluminum with refractory niobium and strength-contributing nickel aims to balance density, strength, and thermal stability. Such compositions are of interest for aerospace and power-generation industries seeking alternatives to conventional superalloys, though industrial deployment remains limited pending maturation of manufacturing and performance validation.
