“…Figures 1-3 present the results of calculations based on ratios (4) and ( 5) for four-and six-component systems based on Fe, Ni, Co, and Cu; Fe, Ni, Co, Cu, Cr and Ti, respectively. Note that we obtained similar results for the case of a five-component system based on Fe, Ni, Co, Cu, and Al (data on the concentration dependence of the lattice parameter and the Debye temperature are given in [4]).…”

Within both the phenomenological approximation and the framework of the principle of additivity of physical quantities of a multicomponent solid solution, including high-entropy alloys, the concentration dependences of the lattice parameter and the Debye temperature are calculated. The principle of additivity can be applied to these physical quantities, since they can be considered indirectly through the radius and mass of atoms as their own, but not collective characteristics of the individual components of the alloy. It is proposed to consider the integral and differential concentration coefficients as the quantitative measures, the values and signs of which allow us to establish the influence of each alloying element, which is represented alternately by all elements of the system, on the values of the lattice parameter and the Debye temperature. The 4-6-components' systems based on Fe, Ni, Co, Cu, Cr, Al and Ti within the equiatomic approximation are analysed.

“…The primary form of the additive is pressed briquettes based on secondary products of plant processing with the size: d  60 mm, l  80 -150 mm. Ash content is 2.8 %, density at 0.855 g/cm 3 . The final product is a filler with a size of 400 ... 600 nm, which is obtained as a result of the thermal decomposition of pressed organic material.…”

“…Therefore, improvement of functional characteristics of water transport is possible through the use of modified polymer [1,2] coatings, which allows to counteract the corrosion destruction of metal surfaces and equipment and metal films us as protective layers [3,4]. At the same time, inhibitors or inhibitory pigments are used to modify the polymer binder.…”

The structure of the developed epoxy coatings using IR spectral analysis and corrosion resistance by determining the permeability index in the aggressive environment of river water during t  6552 h at a temperature range T  258...303  2 K was investigated in the article. It was shown that the process of structure formation of epoxy coatings is influenced by the change in the ratio of nano-disperse and fibrous fillers in epoxy ED-20 oligomer. Significant structural changes for epoxy coatings were observed at wave numbers: ν  570 cm -1 , ν  840 cm -1 , ν  1045 cm -1 , ν  2962 cm -1 , which indicates their degree of crosslinking. A study on the change in the permeability index in the environment of river water was carried out with consideration of rational proportion of dispersive fillers in the epoxy binder, which made it possible to create an effective barrier to the penetration of aggressive ions and water molecules to the base. A decrease in the permeability of protective coatings by 1.8 ... 2.0 times relative to the epoxy matrix was achieved. In addition, a visual analysis of the surface coatings operated under the influence of river water at variable temperatures was carried out. For the epoxy matrix and composites containing one filler, defects in the form of cracks and peeling were observed, which are associated with the course of physical and chemical processes of sorption and diffusion of an aggressive environment. In addition, such coatings are characterized by a tendency to overgrowth with green algae of the genus Spirogyra. For the coatings containing a rational combination of two fillers, the absence of defects and biological fouling was observed.

The results of analysis of literature and own data on the phase composition, electrophysical and magnetoresistive properties of granular film alloys based on Fe and Ag or Au are present. Analyzed the question about system designations of film structures, which adopted in the literature and does not meet their physical nature in its original state and after annealing. A new system of signs ordered and disordered solid solutions without and with the presence elements of granular state; quasigranular alloys, in which the role played granules of ferromagnetic island films; intermetallic and others was proposed. It is established that the electrophysical properties (temperature coefficient of resistance-TCR and strain coefficient-SC) defined conductive matrix as s.s., and in nanoscale granules realized the ballistic conductivity mechanism that does not affect the value of TCR and SC. In granular film alloys s.s. Au (Fe) + granules at the plastic deformation observed abnormal increase in comparison with the elastic deformation value SC (10 times) at a concentration cFe  55-75 аt. %.
