β¦ Synopsis
SHEAR STRAIN (PERCENT1 l?m. 3. Latent hardening in Iithium fluoride for varying pro-strain.
non-orthogonal slip systems in lithium fluoride single crystals is extremely large relative to the latent hardening in other materials which have been similarly tested.@) This fact must be taken into account when discussing the relationship between the flow stress and the dislocation density determined for example by an etch pit method. w The flow stress in these crystals is extremely anisotropi~. Not only the density but the geometric distrib~ltion must be considered. The explanation for this effect is as yet uncertain.? Preliminary results indicate that the latent hardening in potassium chloride is smaller than in lithium fluoride (about 3:l) so that some specific material properties may be involved rather than simply the elastic interaction and network formation between dislocation with non-orthogonal Burgers vectors.c7) The author wishes to thank W. G. Johnston and J. S. Nadeau for experimental assistance and J. D. Livingston for review of the manuscript.
