· Y17Al66Ni17

Y17Al66Ni17 is an experimental intermetallic compound combining yttrium, aluminum, and nickel in a near-equiatomic ratio, belonging to the family of ternary metallic systems with potential high-temperature applications. This composition sits within research into advanced lightweight alloys and intermetallic phases, where yttrium additions are investigated for grain refinement, oxidation resistance, and phase stability in aluminum-nickel base systems. The material is primarily of academic and developmental interest rather than established industrial production.
