· Y17Al5Ni78

Y17Al5Ni78 is a ternary intermetallic compound composed primarily of nickel with aluminum and yttrium additions, representing a research-phase material in the nickel-aluminum intermetallic family. This composition falls within the broader class of Ni-Al based compounds that are of interest for high-temperature structural applications due to their potential for improved strength and oxidation resistance compared to conventional superalloys. The yttrium addition typically acts as a reactive element to enhance oxidation and creep resistance, making this material relevant to emerging high-temperature engineering challenges where conventional nickel-based superalloys approach their limits.
