A STUDY OF DISLOCATIONS IN SILVER CHLORIDE
Abstract
Dislocations in AgCl have been studied through the use of three different types of experiments: absorption edge measurements; tensile tests; decoration experiments. A shift of 1A per percent plastic deformation could have been detected. This is much smaller than the shift of 12A per percent plastic deformation found by Chiarotti. Experiments on the tensile properties of AgCl show that the history of preparation and imprity content of the crystals affects these properties. Tests were run on copper doped samples which showed that the divalent state exhibited strain aging whereas the crystal containing copper in the monovalent state showed no strain aging. Quenching raises the initial yield point by 350% with the evidence pointing toward a large part of the increase being due to quenched in point defects. Photolytic silver in the interior of AgCl locks dislocations and raises the initial yield stress by 60%. Strain aging was found to be accumulative. Part of the increase in yield stress is irrecoverable. A technique for decorating dislocations deep in the interior of AgCl crystals using the Haynes-Shockley method was extended. (Author)
