Purpose of work is research, development of the theoretical foundations of the formation of nanostructured elements in plastically deformed materials and sprayed coatings and methods for predicting the physical and mechanical properties of nanostructured metal composites. The object of study is the process of predrekristallization polygonisation, forming the substructure (nanostructures), sintering, thermal spray coatings, absorption and attenuation of ionizing radiation. The scientific basis for the formation of up to 30% of nanostructured elements in plastically deformed metals and new metal-glass materials and coatings with complex protective properties (high strength, heat resistance, damping capacity, and capable of absorbing the ionizing attenuate, in particular - and X radiation), which include relationship of nanostructured and protective characteristics. The regularities of the aluminum matrix forming compositions by hot pressing a mixture of powdered aluminum products with fillers (hollow glass microspheres, and powders with further isothermal aging in the temperature range of 550 ... 660 ° C). Set new patterns and mechanisms of interaction between the diffusion flux of ionizing radiation to the structural elements and the unit cell metal-glass composite materials and coatings, filled with hollow glass microspheres and solid glass particles. Technological recommendations for obtaining electric-arc coatings and metal composites with nanostructured elements, products obtained by cold working pressure; modeling techniques mechanical and thermal properties of the material through the use of interatomic interaction potentials.
