    For the cubic to cubic, fee ¡ª Ll2 transition, four translational variants (antiphase domains, or APD's) of the Ll2 are possible. Three types of interfaces can occur between these domains (antiphase boundaries, or APB's) having 1/2(110)-type displacement vectors. For the cubic to tetragonal, fee ¡ª DO22 transition, within each rotational domain of the tetragonal DO22 four translational APD's (with three types of APB's) are possible. Displacement vectors of the APD's are the same as for the Ll2 APD's (in fee coordinates). In the tetragonal coordinates of the DO22 the vectors are l/2[110], 1/2[10 j]t, and l/2[01 {],. While each of the Ll2 APB's can be identified by dark-field imaging with different superlattice reflections, the 1/2(10j^-type interfaces of the DO22 cannot be distinguished from each other (the reflection conditions for the IA/mmm spacegroup of the DO22 forbid hkl with h + k + I = odd).
