Modern nickel-based superalloys contain high concentrations of rhenium that allows the improvement of their creep strength. The high levels of rhenium, however, results in the formation of topologically close-packed phases (TCP) which have a negative influence on its properties. The addition of ruthenium was found to reduce the precipitation of nano-sized TCP phases, but the reasons have not been established. In this paper, by using an ab-initio approach, we studied the e ffect of rhenium and ruthenium on the structural properties of Ni matrix as well as the TCP phases. We demonstrate that Cr, Mo and W are the most e ffective additions to provoke the formation of TCP phases, whereas ruthenium has a destabilizing e ffect.
Keywords: Ab initio calculations, rhenium eff ect, superalloys.
