Abstract
This paper presents calculations of screw dislocation cross slip in copper and nickel systems, using the nudged elastic band method and interatomic potentials based on the effective-medium theory. The validity of recent attempts to predict cross slip activation energies by ‘elastic scaling’ between fcc metals is investigated, finding that reasonable predictions can be made using the approach suggested by Rasmussen [T. Rasmussen, Phil. Mag. A 80 (2000) 1291]. The experimentally determined cross slip activation energy and the minimum stable screw dislocation dipole height for copper are explained on the basis of cross slip of jogged screw dislocations.
