The deformation and fracture of metals and alloys within the auto-wave concept are in the field of interests.

During recent years the scientists of our Laboratory (ISPMS) have found experimentally for a range of metals and alloys that plastic deformation at all its stages is prone to localization. The localization patterns observed are wave-like in character; the kind of wave depends on the acting law of work hardening. There are only four of them: single deformation fronts move in the easy glide stage for single crystals and in a yield plateau for polycrystals; a system of equidistant mobile localized-strain centres in the linear hardening stage; spacio-periodic structure of plastic strain localization regions in the Taylor parabolic work hardening stage and the last one is the structure of nonuniform mobile strain-localization regions peculiar to the final (prefracture) deformation stage.
