Essay

It is shown, that the kinetics of the thermoactivated plasticity of supersaturated alloy is defined substantially by interaction of dislocations with particles of the second phase. For the first time the influence of an electronic condition of the sample on low temperature jump-like deformation (LTJD) in Al-Li alloys with various phase structure is studied. Influence of a microstructure and electronic condition of the sample on LTJD of UFG aluminium is investigated. It is revealed that the grain reduction in a submicronic range, unlike millimetric, promotes development of LTJD in aluminium.
