It was recalled that antiphase boundary tubes could be identified by transmission electron microscopy, in some intermetallic compounds, because of the atomic relaxations around them. Atomistic simulations were used here in order to investigate the relaxation of the tubes. The most important mode of relaxation which produced contrast could be interpreted in terms of the expected supplementary fault displacements of the antiphase boundaries on (111) planes.
