On the Kinetics of Plastic Deformation of Some Alkali Halide Crystals

A study is made of the kinetics of plastic deformation in LiF, NaCl, KCl, and KBr crystals. This includes the non‐uniformity of the plastic deformation, the strain rate dependence of this non‐uniformity, the strain rate dependence of the flow stress, and the dislocation structure of the deformed crystals. In the above crystals a regular change of the kinetics is found for a decrease of the elastic anisotropy factor A = 2 C 44 /( C 11 – C 12 ). The correlation of the macroscopic behavior of the crystals with their elastic anisotropy is assumed if other conditions are similar.
