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 paper examines the effect of technological parameters of gas nitriding (temperature and time) on the phase composition, structure, microhardness, and wear resistance of the Cr28 ferritic class corrosionresistant steel. Nitriding was carried out in an environment of dissociated ammonia in the temperature range of 550-950 С. The dependence of the phase composition of the formed coatings on the nitriding temperature was established. X-ray structural, metallographic, and durometric analyses determined that the following phases are formed due to nitriding: Fe2N, Fe4N, Fe, Fe, and CrN. The maximum microhardness of 15.5-16.0 GPa was recorded for coatings on Cr28 steel after nitriding at a temperature of 550 С. The influence of the annealing temperature on the microhardness of the nitrided coating was analyzed. A decrease in the microhardness of the nitrided coating on Cr28 steel starting from the annealing temperature of 600 C was recorded. It was established that the minimum reduction in microhardness at an annealing temperature of 750 С is characteristic of Cr28 steel nitrided at a temperature of 550 С. The optimal mode of nitriding (temperature 550 C, time 6 hours) was determined, which allows for obtaining the maximum abrasive resistance of Cr28 steel after nitriding. At the same time, a 2.8-fold increase in the wear resistance of nitrided Cr28 steel compared to the original structure is recorded.

Complex study of electrophysical properties (the electrical resistivity r and the temperature coefficient of resistance (TCR) b) of thin-film samples based on ferromagnetic alloy Ni80Fe20 (permalloy) and noble metal Ag in a wide composition range and within the range of thickness 20-100 nm done. Thin films were obtained by the method of electron-beam co-evaporation technique at room temperature. Their composition was investigated using the method of X-ray spectrometry. The phase state was analyzed by the electron diffraction method. It was demonstrated that the crystal structure of thin films stays unchanged during the annealing process to 500 K. The size and concentration dependences of r and b values were obtained. The corresponding maximum and minimum at the concentration of Ag atoms of 50-60 at.% observed at the dependences r(cAg) and b(cAg). Size dependences r(d) and b(d) associated with the size effects in thin-film materials.
