Abstract : Strain aging has been ob erved around room temperature in silver chloride single crystals containing a few parts in 100,000 impurity. On the basis of the aging kinetics, it is possible to account for the effects in terms of dislocation pinning by polyvalent cation solutes. A sharp lower yield point often appears in the stress vs strain curves; their general shape is di cussed qualitatively in terms of current concepts of dislocation multiplication and unpinning.
