The aim of the work is to develop a technological process for obtaining profiles of mass and special purpose from high-strength aluminum alloys. To achieve this goal it is planned to build technological phase diagrams of alloys of Al-Cu-Mg-Zn-Si systems, to investigate the influence of alloying and impurity elements on the change of phase composition of alloy depending on temperature-speed parameters of casting, plastic deformation and subsequent heat treatment modes. as well as the formation of the structure and properties of profiles. Various methods of alloy research will be used: thermodynamic calculation of changes in their phase composition, DSC (differential scanning calorimetry) and DMA (dynamic mechanical analysis) methods to determine critical points of alloys, methods of mathematical and computer modeling. Methods for controlling the temperature-velocity parameters of casting, plastic deformation and heat treatment modes in the technological processes of extrusion and roll casting-rolling of alloys will be developed.
