Creation of mathematical models for the study of plastic flow, analysis of mixing of components and determination of mechanical properties of metal compositions; development of the design of the installation for the implementation of intensive plastic deformation by screw extrusion. Research method. Mathematical modeling, optical and scanning electron microscopy, computer data processing. The results. Models of processes of intensive plastic deformation (IPD) of metals designed to study the nature of plastic flow and the stress-strain state of materials in these processes have been developed. A model of metal mixing during intense plastic deformation has been developed. It is shown that in the IPD of layered metal compositions, in the process of mixing the layers, a structure similar to those found in the Earth's lithosphere arises. On this basis, a new approach to the creation of materials with internal architecture is proposed. The sketch project of installation of screw extrusion and drawings of its main knots is made. Predictive use of work results. The results of the work can be used in the development of technologies for obtaining new materials for precision and miniature products.
