A unique microstructure was developed in a ternary alloy composition (Ni-12 at.% Al-11 at.% Zr) containing two coupled intermetallic phases (Ni<inf>3</inf>Al and Ni<inf>5</inf>Zr) consisting of colonies with interconnected lamellae that degenerate into irregular morphologies during growth. This architecture exhibits excellent high temperature microstructural stability, exceptional high strength with adequate tensile ductility at room temperature, and outstanding cyclic oxidation resistance.falseIntermetallic eutectics | Mechanical properties | Microstructure | Oxidation | Phase equilibriaArticle67-71December 201814arJournal14
