N2 - Transmission electron microscopy (TEM) methods were used to analyze the deformation-induced antiphase boundary (APB) tubes in a Ni3Al
single crystal. A high density of tubes is observed after
room-temperature deformation showing strong contrasts in some
fundamental reflections. This is not expected from a hard sphere model
of the APB faults bounding the tubes since in this case the APB faults
are just chemical faults (displacement vector RC→=1/2⟨110⟩). The TEM analysis shows unambiguously that the APB faults contain a small additional structural displacement vector RS→. RS→ lies in the plane of the fault and is perpendicular to RC→.
