title = "Influence of Ru and Cr on the heat-treated microstructure of Ni-based superalloys",
abstract = "The effects of ruthenium and chromium contents have been investigated on phase transformation temperatures and the morphology of γ' precipitates as well as microstructural stability in high refractory Ni-base superalloys. The solidus and liquidus temperatures were determined by differential scanning calorimetry (DSC), suggesting that the addition of Cr resulted in a decrease in solidus/liquidus temperatures while the Ru addition (3.5 at.\%) had the neutral effect. The morphology of γ' precipitates in the heat-treated microstructure was changed under the influence of the Cr and Ru additions, suggesting that Ru and Cr contents affected the γ-γ' lattice misfit through changes in the associated partitioning to the constituent phases. The microstructural instability has been investigated at 1000 °C. High levels of Cr addition (8 at.\%) strongly promoted the formation of TCP phases, while Ru improved the microstructural stability to some extent.",
