摘要：
Weak-beam observation electron microscopy has been performed on 1/3 <1120= superlattice dislocations lying on the (1100) prism planes in Ti3Al single crystals deformed at room temperature. The dislocations observed are mostly of edge character. They are found to dissociate into four partials on the prism plane; a superdislocation into two unit dislocations with an associated antiphase boundary in between and the latter again into partials bounding a complex stacking fault. © 1990 Taylor & Francis Group, LLC.
