Abstract

Results from large-cell Monte Carlo renormalization group calculations for the effects of ordering and clustering on site percolation thresholds in bcc alloys are presented. The results demonstrate that for the case of relatively small positive difference in bonding energies between unlike and like atoms (0.015 eV/bond), the site percolation threshold is lowered from its conventional value of ∼0.25 to 0.16. Conversely, for a small negative difference in bonding energies (-0.015 eV/bond), the threshold increases to ∼0.30. The implications of these results on corrosion/passivation in the context of the integrity of materials for nuclear power systems are indicated.
