Abstract
The diffraction‐contrast characteristics of twinning partials have been examined for | g · bp | = 1/3 and 2/3, where g is the operating reflection and bp is the Burgers vector of the partial. The results can be rationalized in terms of the intensity profiles computed by Tunstall and Goodhew for the partials bounding overlapping stacking faults. Further, when | g · bp | is 2/3, the interface dislocations exhibit, for the same g, variations in their contrast. Arguments for rationalizing these observations are developed. A simple analytical procedure for differentiating between twins and complementary twins is also proposedThis publication has 3 references indexed in Scilit:
