Methods have been developed to ensure high mechanical properties during plastic forming of structures of a new welding alloy of the Al - Mg- Transition Metals - Rare earth elements system for aerospace engineering. A two-stage approach to deformation has been developed, when at the first stage deformation is performed under conditions of large shear deformations for a more uniform redistribution of phase components and a decrease in the size of the grains - homogenization of the material due to mechanical action, and at the second stage - the formation of the structure.
In this work, using a unified theoretical approach, the analysis of the processes of visco-plastic forming of typical mechanical engineering structures with homogeneous and structurally heterogeneous materials. The theoretical approach is based on a closed system of equations of the theory of plastic flow of continuum mechanics, taking into account the visco-plastic properties of materials. This approach made it possible to provide system design of structural forming processes.
