Generalized stacking faults in model lattice of ordered Fe-Si alloys

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The energies of the generalized stacking faults lying on {110} and {112} planes are calculated for Fe-Si alloys with the DO3 long-range order for concentrations 10–25 at. % Si. In the used model, the interaction between atoms is described by the series of three central interatomic potentials fitted to experimental data. The lattice relaxations perpendicular to the stacking fault plane are considered. The displacement vectors corresponding to stable antiphase boundaries are found and some consequences for the structure of superdislocations in the DO3 superlattice are mentioned.
