The annealing of slightly bent AgCl single crystals

Abstract

Experiments on slightly bent AgCl crystals, using an etch-pit technique to reveal dislocation sites, have shown that the behaviour on annealing depends on the size of the crystal sub-structure: when there is a fine sub-structure dislocations join the sub-boundaries but with a coarse sub-structure the dislocations form polygon walls. It is shown that dislocations of minority sign are introduced in bending.
