“…The periodic variation predicted by Cai et al 9 observed, probably because mobile dislocations always contain some part where the dissociation width is more favourable to kink pair nucleation. Similar results in Ge 22,23 and GaAs 24 also yield indications of dislocation pinning by impurities.…”

In an attempt to establish a correct physical description of the mechanical behaviour of a crystal, the present paper presents first a critical review of two dislocation mobility processes: glide in covalent crystals, and pure climb at high temperatures. Models are presented together with experimental data to test them. The study then gathers available information about the way dislocations multiply, are held up in the substructure and the resultant work hardening of the crystal.

“…For the secondary system KQ we repeated the deformations also at T 520 C and arrived at LHR (520 C) 1.59. The mobility exponent m (520 C) being 1.9 [16] we find from Eq. (8): LHR (581)/LHR (520) 1.056 which is to be compared with 1.062 (experiment).…”
