The microstructure stability and creep properties of Ir-base refractory super-alloys (It-Nb and Ir-Zr) with an fcc and Ll 2 two-phase structure were investigated. An orderly arrayed structure composed of cuboidal coherent Ll 2 precipitates was observed in the Ir-Nb alloys. By a different heat treatment, a maze structure and a discontinuous coarsened lamellar structure were obtained in the Ir-Zr alloys. Creep behavior was investigated for samples with these three kinds of microstructure between 1 500 and 1 800°C. The creep behavior was explained according to microstructural changes before and after creep.
