Abstract (englisch):

We introduce a novel material based on microstructural engineering of intermetallics at an ultrafine scale. A unique microstructure was developed in a ternary alloy composition (Ni-12 at.% Al-11 at.% Zr) containing two coupled intermetallic phases (Ni3Al and Ni5Zr) 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.
