Abstract
It is assumed that transformations of the splitting of a screw dislocation are continually repeated during its motion, and thus the screw dislocation crosses into different {110} and {112} planes [1]. On the basis of this mechanism a theory of the composite slip on {110} and {112} planes is established, and the dependence of the orientation of the slip plane on the orientation of the maximum resolved shear stress plane is calculated. The results are compared with the measurements of Taoka et al. [8] and Šesták and Zárubová [9]. Further it is shown that the same mechanism can account for the strong temperature dependence of the flow and yield stress.Keywords
