Object of study - alloys under the influence of shock loading and electromigration. Purpose - to study phase transitions in binary alloys under intensive external influences on the system. In particular, to investigate experimentally, to develop a theory and computer models of formation and decomposition of supersaturated solid solutions at fast high-speed deformation of alloys. To investigate the structural evolution of two-phase alloys under the influence of current. 1. Using new loading tool, constructed in the course of work, authors discovered a new effect - acceleration of the decomposition of the supersaturated solid solution of tin in lead by intense shock loading. This effect is competitive to the effect, which was discovered by researchers from IMF NAS of Ukraine earlier - the formation of supersaturated solid solutions under the influence of intense shock loading. 2. Theoretically and with the help of molecular dynamics the possibility of formation of solid solutions in the concentration areas of the intermediate ordered phases, was demonstrated, under sufficiently intense impact on the metal. 3. Non-equilibrium phase diagrams of binary alloys under conditions of intense shock loading, were built theoretically. 4. A new method for studying the evolution of the structure of two-phase alloys under the influence of electromigration 5. A new technique to study solid state reactions in the systems of copper-tin and nickel-tin under the influence of electromigration.
