In the alkali halides the critical resolved shear stress for slip on {100} planes becomes strongly temperature dependent below a critical temperature. In addition the activation volume decreases below 100 b 3 ( b Burgers vector). This behaviour can be explained in terms of a large intrinsic resistance to dislocation motion on this slip plane. The Peierls stresses for {100} slip are of the order of 10 −2 c 44 ( c 44 shear modulus for the {100} plane).
