Abstract:

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.
