Abstract
Dislocation walls consisting of double arrays were revealed on the (001) surface of deformed, and then annealed, crystals by an etch hillock technique. It was found that dislocations in the wall have the Burgers vector ½<111>, and that the wall was split into two arrays at the surface but had nearly merged into a single array below the surface. This particular configuration may be well interpreted by assuming that the wall is composed of two kinds of dislocations with Burgers vector having a common edge component but alternate screw component, and by taking the image force of each dislocation into consideration. The analysis indicates that the depth over which the split of the wall extends is approximately equal to the spacing between dislocations in the wall.
