Multi-phase quasicrystalline alloys for superior wear resistance

Design of quasicrystal-based alloy with three phases; λ-Al13Fe4, i-phase, and τ-AlCu for improved wear resistance. (a) quasicrystal-based alloy shows ductile behavior due to dominant τ-AlCu phase, (b) quasicrystal-based alloy shows harder mechanical property due to decreasing τ-AlCu phase and increasing i-phase than the alloy at “A state”, (c) quasicrystal-based alloy shows a favorable tribological performance because of dominant i-phase.223
