✦ Synopsis

Abstract

Using the etch pit technique both the distribution and density of dislocations in undeformed and dynamically deformed nominally pure and Sr^2+^ or Pb^2+^ doped KCl crystals are examined. Additionally, the role of specimen geometry in the plastic deformation within the I deformation stage is determined. For all the crystals examined the relationship between screw dislocation density and plastic flow stress obeys the formula τ ⋍ ϱ~sc.~^1/2^.

## Abstract Using the X‐ray diffuse scattering technique, KCl crystals with various Ba impurity concentrations (0.0027–0.353 at. %) have been studied. Isointensity curves for all the crystals studied were constructed, which permitted discovering a strong concentration dependence of the diffuse scat
