摘要：Refractory elements are added to strengthen the Ni-based superalloys for turbine disks, while the effects of these elements on the oxidation resistance remain to be investigated systematically to continually improve the working temperature. In this work, the effects of typical strengthening elements, including Ta, W, Mo, Hf and Nb, on the isothermal oxidation behavior of Ni-based superalloys at 900 degrees C were studied. The results indicated that increasing concentrations of Ta, W, and Mo enhanced the oxidation resistance, while adding 4 wt% Nb and 2 wt% Hf accelerated the oxidation rates in different degrees, which was explained in terms of diffusion and phase precipitation.
