Transmission electron microscopic observations were made of dislocations which consisted of 2 Shockley partials that bounded superlattice intrinsic stacking faults, as produced by compressive deformation at room temperature. The results showed that most of the faults were truncated loops. That is, the partials which bounded superlattice interstitial stacking faults had the same Burgers vector. The superlattice intrinsic stacking faults were generated from antiphase boundary-coupled dislocations. The addition of Pd did not have the same effect upon superlattice intrinsic stacking faults as did B doping. No connection between the superlattice intrinsic stacking fault density, and ductility, could be found.
