Abstract
Two Ni-based superalloys (one Ru-free and one containing 1 at.% Ru) were comparatively studied by Atom Probe Tomography and complimentary techniques. Ru addition impedes precipitation of the Ï phase at 950 °C. Ru partitions nearly equally to the γ and Ï phase. Neither reverse elemental partitioning nor destabilization of the γⲠphase is detected when adding Ru. We propose an increase in the γ/Ï lattice misfit caused by Ru as a major reason for impeded nucleation of the Ï phase.
