• The slow motion of an extended dislocation accompanied by heterogeneous distribution of solute atoms in its hexagonal layer was studied on the basis of the interaction mechanism between solute atoms and dislocations proposed by the present author. In the case of a very small stress, the velocity υ was expressed by υ= 0.4 D/b f/f_0 where D is the diffusion coefficient of the solute atoms in the alloy, b the strength of the perfect dislocation, f the applied shear stress, f_0 the critical shear stress of the alloy due to the locking force by solute atoms. The slow motion of an extended dislocation might be stable under the applied force less than 0.6〜0.8 f_0 depending on the width of the extended dislocation.
