Evidence is presented to show that plastic deformation of NaCl single crystals by transverse bending arbitrarily takes place in one of two distinct ways which result in quite different stress‐strain behavior. The crystals deform initially by glide either along the {110} slip planes normal to the bending plane or along the {110} planes normal to the neutral plane. A higher rate of work hardening is observed when bending activates slip on the {110} planes normal to the neutral plane. Reliable studies of work hardening and related effects in NaCl single crystals therefore cannot be made in flexure unless careful attention is given to this orientation effect.
