Atomic projection of hexagonal Cr_2Ta Laves phase has been directly imaged by Z-contrast imaging at an atomic scale,which provides much more detailed information compared with the conventional coherent high-resolution imaging.Stacking faults with sequence of …stst＇st＇stst＇… were identified,where the three-layer stacks（Ta-Cr-Ta）switch from t to t＇ type.The defect configuration at an atomic level in the present study is expected to provide useful information for understanding defect structures in the Laves phase.
