Abstract
Effects of Ru on the compressive creep of Ni-based single-crystal superalloys were investigated at 750 and 900 °C. The addition of Ru improved the creep strength at 750 °C. It enhanced the dissociation of dislocations in the matrix channels and would inhibit the nucleation of the a〈1 1 2〉 dislocation ribbons which shear the matrix and the precipitates; as a result, the mechanical-twin formation was also impeded and creep strength was increased. However, Ru addition did not improve creep strength at 900 °C.
