Essay

Found that low-temperature deformation of Al jump - like deformation is athermanous process in alloys AMg-3, AMg-6 at low and room temperatures ranging Hopping deformation is the same thing. The primary in the formation of surges is a force to overcome the potential barrier dislocation group. First discovered instability of plastic flow with amplitudes various scale during deformation of alloys Pb - (4-55) at. % In in different states electronic system. First appearance of jumps in the superconducting and normal states, then the metal is determined by the change athermanous detachment of dislocations from obstacles. First found suppression of jump - like strain AMg-3. With electronic irradiation. Radiation - induced effects is determined by thermal flash and nonlinear vibrations of the crystal lattice (discrete breathers).
