Evidence of slip on the {211} planes, over mesoscopic distances, in 50:50 alloys was explained in terms of a low specific energy of the stacking faults on the {211} planes, and was related to the formation of coherent twins with {211} composition planes during plastic deformation at relatively high temperatures. It was noted that one of the configurations, of a/2<111> screw dislocations, which had been studied in the literature was able to account for both {211} slip and for the nucleation of twinning.
