| Abstract | The synergetic effect of Re and Ru on γ/γ′ interface strengthening of Ni-base SC superalloys has been investigated by performing DMol3 calculations. Results show that the synergetic effect of Re and Ru on the interface strengthening is better than that achieved by the individual Re or Ru due to Re-d/Ru-d, Re-d/Ni-d and Ru-d/Ni-d hybridizations. The electronic mechanism underlying the synergetic effect of Re and Ru on γ/γ′ interface strengthening is related to the charge transfer of electrons and the enhancement of d-bonding hybridization among Re—Ru, Re—Ni and Ru—Ni atoms. |
