Two samples (one of them twinned) were plastically deformed in compression at room temperature. The applied stress was parallel to <110> in the matrix of the twinned crystal, and to <131> in the twin. The other sample was deformed along a <132> direction. Activation of glide systems in both samples was studied by transmission electron microscopy. The structure contained mainly long segments of screw and 60° dislocations and edge dipoles resulting from the dragging of jogs. Weak-beam observations showed that all of the studied dislocations were dissociated into two Shockley partials. The stacking-fault energy ranged from 8.8 to 14.7mJ/m2.
