A Dnipro-5M installation was used for detonation spraying. The flow rate of acetylene and oxygen, the air pressure for ejecting detonation products, and the spraying distance were varied in the spraying process. The structure of the coatings was examined by optical microscopy and electron probe microanalysis. The adhesion of the (Ti, Cr)C–Ni coatings was determined by the pin method, and the porosity was measured by the linear Rosival method. In the detonation spraying of (Ti, Cr)C–Ni composite powders, particles of double titanium–chromium carbide refined to 6–7 μm, contributing to the development of a fine and uniform structure of the detonation coatings. It was found that the detonation spraying parameters should be adjusted upward when the nickel content changed from 18 to 33 wt.% in the (Ti, Cr)C–Ni composite powders. The increase in the nickel content from 18 to 33 wt.% resulted in higher adhesive strength and lower porosity of the coatings. In the research, an acceptable level of adhesive strength and porosity could not be reached for the (Ti, Cr)C–18 wt.% Ni detonation coating.

The associate solution model (ASM) was used as a calculation tool. The results of the calculations correspond to the experimental data on the integral mixing enthalpy, presented in the first part of the work, and reveal the regularities of changes in other thermodynamic functions and the features of interaction between components in these liquid alloys. It was established that the excess thermodynamic mixing functions in each system have negative values, which are determined by pair interactions between Fe, Co, Ni, and Cu as electron acceptors and Ti and Zr as electron donors. The trend of changes in the minimum values of excess thermodynamic mixing functions of the systems shows an increase in their absolute values along the 3d-series from iron to nickel and a significant decrease for copper, which corresponds to a change in the acceptor capacity of metals along the transition series. The temperature dependence of the thermodynamic mixing functions consists in an increase in negative deviations from ideality and an increase in the intensity of interaction between components with a decrease in temperature. The formation of glass-forming liquid alloys from pure metals is accompanied by an increase in the thermodynamic stability of the liquid phase, which is reflected in negative values of the Gibbs mixing energy. In the range of 800–1873 K, the Δ_m<i>G</i> function of liquid equiatomic alloys of the systems considered shows values at the level of –20...–35 kJ/mol.

The relative density of the sintered samples reached 99.4%. The phase composition, microstructure, and mechanical properties of WC–10 HEA hardmetals were studied by X-ray diffraction, scanning electron microscopy, and microindentation. The effect of the NiFeCrWMo HEA binder on the microstructure and mechanical properties of WC–10 HEA hardmetals in comparison with the conventional VK8 hardmetal (WC–8 Co) was determined. The WC–10 HEA hardmetal consolidated by EBS consisted of WC grains, a NiFeCrWMo HEA binder with a bcc structure, and a small amount (3.5%) of complex carbide (Ni, Fe, Cr)_xW_yC_z, whereas the amount of the complex carbide after SPS increased to 47% due to longer sintering and pressure application. No noticeable growth of WC grains was observed during sintering of the WC–10 HEA hardmetal because of the multielement composition of the NiFeCrWMo HEA binder and the formation of complex carbide (Ni, Fe, Cr)_xW_yC_z layers, preventing the growth of WC grains.

The study focuses on a porous nickel-based material produced by a sequential multistep process that includes the self-assembly of polystyrene spheres, sintering, electrolytic deposition, and subsequent removal of polystyrene to achieve the desired structure. The study covers the process of transition from elastic to irreversible deformation. The objective of this study is to apply the finite element method to model the transition process to reveal the relationship between the structural characteristics of materials, such as porosity and coating thickness, and their mechanical properties. The yield surface was constructed by computational modeling on a representative cell with a number of points in the (<i>p</i>, <i>τ</i>) plane for two cases of opal structure: a highly porous uncoated structure and a structure with an additional solid phase layer. One of the results included approximation of the yield surface with a phenomenological Deshpande–Fleck crushable foam model available in finite element modeling packages. The conclusions show that the effective plastic properties of materials with an inverse opal structure significantly depend on their porosity level and the presence of additional coatings. The yield curve plotted for a porosity of 0.9 is close to the associated plastic flow law, allowing the material’s behavior under loading to be assessed from the uniaxial stress state. However, for a structure with medium porosity and an additional coating layer, the surface becomes significantly unassociated, with a discrepancy of almost 30%.
