The energy factor of edge dislocations in planes of important zone axes and the dependence of the energy factor upon the edge-screw composition angle theta for various dislocations were analyzed. The relationship between dislocation parameters and the choice of slip system was considered, based upon the criterion of minimum dislocation energy.
