Dissociation Processes in the Orthorhombic O Phase
Published online by Cambridge University Press: 01 January 1992
Abstract
In the orthorhombic phase of Ti2AlNb-type, the occurrence of different dissociation modes of dislocations, glissile in the (001) basal plane is reported. [100] and 1/2[110] dislocations usually dissociate in order to form antiphase boundaries. Detailed weak-beam observations show that [100] dislocations, as well as [010] dislocations formed by interaction of 1/2<110> dislocations, can dissociate into three-fold configurations containing a pair of stacking faults.
