Single crystals of Ti-56at%Al were deformed in compression in 2 selected orientations. The sample strained along one orientation was found to contain a profusion of faulted dipoles when compared with that strained along the other. Based upon an earlier model for faulted-dipole formation, a crystallographic analysis of the nature of the leading and trailing partials of <011] dislocations as a function of load orientation, explained the orientation dependence of the observed difference in faulted-dipole density.
