Calculations were made of screw-dislocation cross-slip by using the nudged elastic band method, and interatomic potentials which were based upon the effective-medium theory. The validity of attempts to predict cross-slip activation energies by means of so-called elastic scaling between face-centered cubic metals was investigated. It was found that reasonable predictions could be made by using the Rasmussen approach. The experimentally determined cross-slip activation energy, and the minimum stable screw dislocation dipole height, were explained on the basis of the cross-slip of jogged screw dislocations.
