Karazin popup.description2 The object of investigation - single and polycrystals of Pb and Pb-In alloys, polycrystals of pure Al and Al-Mg alloys. The aim of work - complex investigation of instable plastic flow in metals with different electron subsystem state, determination of physical phenomena during instable plastic deformation, the regularities of instable plastic flow of industrial Al - Mg alloys. The method of investigation - deformation of metal with constant rate at low temperatures, statistic investigation of low temperature load drop deformation. The regularities of low temperature plastic deformation in pure lead, Al and their alloys and the influence of deformation and impurity defects on this phenomena have been investigated. Firstly consistently the instable plastic flow with micro load drops in Pb -In alloys in superconducting state have been researched. The instability on several industrial alloys has been investigated. The experimental data have been analyzed with the help of thermomechanical instability of plastic flow models and models of forced overcoming of dislocation obstacles.
