Displacive processes and phase transformations
Two basic displacive processes can be considered, namely displacements of crystal parts as rigid blocks and shuffling of atomic planes. The many-body potentials are used for the interatomic forces. General displacements of atomic planes are examined, i.e. γ-surface type calculations are applied to single plane shuffling and alternate shuffling of every other atomic plane producing in combination with homogeneous deformation the hcp structure.
