The results. The extreme conditions of synthesis under the action of high pressure can control the structural and functional properties of composite nanomaterials in order to optimize them according to the tasks. The high pressure torsion is an effective and promising method of obtaining new heterophase nanostructures consisting of densely packed, ultra-dispersed and interacting phases. The uniform distribution of fractions, the reduction of their sizes, the appearance of anisotropy, and the change of interphase interactions can be controlled by the intensity of plastic deformation. Predictive use of NDR results. The synthesis of new structural and functional materials using intensive plastic torsional deformation under high pressure is an environmentally beneficial alternative to traditional methods of powder metallurgy and metallurgical processing for the industrial sectors needs.
