    Microstructural evolution of DS CM186LC during creep and thermal exposure

    Thermal exposure tests were carried out at the same temperature and duration as those of creep tests. Growth of γ′ either in the matrix or in the interdendritic regions was observed during high temperature the...

    High temperature mechanical properities and creep crack initiation of DS CM186LC for nozzle guide vane

    The second generation DS alloy, CM186LC is used in the as-cast and double aged condition which has creep-rupture properities equivalent to the first generation single crystal alloys CMSX-2 and CMSX-3. In produ...

    Quantitative models on corrosion fatigue crack growth rates in metals: Part II. application of fatigue crack growth rate modeling for nickel-based superalloys at elevated temperatures

    Nickel-based superalloys exhibit sustained load crack growth at elevated temperatures, which significantly contributes to the total fatigue crack growth rate when Kmax is above the threshold value for sustained l...
