Introduction. The processing capability of milling a metal-matrix composite based on Inconel 625 with the addition of NiTi-TiB2, obtained by laser sintering, is investigated. The composite is intended for turbine blades manufacture and has strength characteristics close to Inconel 625, however, due to the addition of TiB2, its’ heat- and wear resistance is higher. This material is new; its machinability has not been studied yet. The aim of the work is to determine the technological capabilities of milling with end mills of this composite. Investigations. The new composite is milled with end mills, and recommendations on the selection of cutting speed, milling depth and width are obtained. Experimental Methods. Measuring end mill wear and cutting force. Wear is assessed by the flank chamfer using a microscope, and cutting forces are measured with a Kistler 9257B dynamometer. Milling is carried out at three speeds: 25, 35 and 50 m/min. To determine the optimal parameters of the depth and width of milling, the following ratios are used: 1: 1, 1: 4; 1:16, while the volume of chips removed per unit of time remained constant for all ratios. Results and Discussion. The back surface of the cutter teeth wears out more intensively. After reaching the wear chamfer along the flank surface of a value equal to 0.11 - 0.15 mm, there is a sharp increase in forces and brittle destruction of the tooth. Milling at a speed of 25 m/min guaranteed 28 minutes of stable operation, after which the amount of wear quickly approached the critical value of 0.11 mm, at a cutting speed of 50 m/min, critical wear occurred already after 14 minutes. The dependences of the cutting force on time for all selected cutting speeds, throughout the test time, have an increasing character, which indicates the effect of wear of cutters on cutting forces. It is found that the durability of cutters increases with increasing width and decreasing the depth of milling.

Currently, metal–matrix composite materials are some of the most promising types of materials, and they combine the advantages of a metal matrix and reinforcing particles/fibres. Within the framework of this article, the high-temperature synthesis of metal–matrix composite materials based on the (Ni-Ti)-TiB2 system was studied. The selected approaches make it possible to obtain composite materials of various compositions without contamination and with a high degree of energy efficiency during production processes. Combustion processes in the samples of a 63.5 wt.% NiB + 36.5 wt.% Ti mixture and the phase composition and structure of the synthesis products were researched. It has been established that the synthesis process in the samples proceeds via the spin combustion mechanism. It has been shown that self-propagating high-temperature synthesis (SHS) powder particles have a composite structure and consist of a Ni-Ti matrix and TiB2 reinforcement inclusions that are uniformly distributed inside it. The inclusion size lies in the range between 0.1 and 4 µm, and the average particle size is 0.57 µm. The obtained metal-matrix composite materials can be used in additive manufacturing technologies as ligatures for heat-resistant alloys, as well as for the synthesis of composites using traditional methods of powder metallurgy.

A possible application of a metal powder composition made of a high-temperature nickel-based alloy with high heat strength (the material is analogous to Inconel 718) in selective laser melting (SLM, an additive manufacturing technology) was considered. Peculiarities of material formation in the course of selective laser melting of the metal have been researched, and the mechanical properties of the material were determined. The effect of the thermal treatment mode on the mechanical characteristics was investigated. It was shown that the tensile strength of samples made of a high-temperature nickel alloy when the samples have not been subjected to thermal treatment is ~950 MPa; samples subjected to thermal treatment is ~1070 MPa.

Additive technologies open up new possibilities for creating materials with controlled structural features including ceramic composites. Such composites have good strength properties, fracture toughness and toughness. But not all properties are studied well. In order to predict the mechanical behavior of transformation-hardened ceramic composites with a controlled structure under dynamic loads, it is convenient to use methods of numerical analysis.The aim of this work was to investigate the influence of loading speed on microstructure evolution of ZTA nanocomposites obtained by additive tecnology of fused deposition modeling. Within the framework of the study physical and mathematical model that is used in computational mechanics of materials is developed. In the paper is shown the influence of the loading rate on the strain rate in the region of the shock transition for materials based on Al2O3 - 20%ZrO2 system. The research shows nonlinear effects under intense dynamic loads in the shown composite materials are bound up with either the processes of self-organisation of deformation modes at the mesoscopic level or the occurrence of martensitic phase transformations in matrix volumes adjacent to the strengthening particles.

Ultra-high performance (UHP) concrete is a special type of fibrous cementitious composite that is characterized by high strength and superior ductility, toughness, and durability. This research aimed to investigate the resistance of ultra-high performance fiber-reinforced concrete (UHPFRC) against repeated impacts. An adjusted repeated drop mass impact test was adopted to evaluate the impact performance of 72 UHPFRC disc specimens. The specimens were divided into six mixtures each of 12 discs. The only difference between the mixtures was the types of fibers used, while all other mixture components were the same. Three types of fibers were used: 6 mm micro-steel, 15 mm micro-steel, and polypropylene. All mixtures included 2.5% volumetric content of fibers, however with different combinations of the three fiber types. The test results showed that the mixtures with the 15 mm micro-steel fiber absorbed a higher number of impact blows until cracking compared to other mixtures. The mixture with pure 2.5% of 15 mm micro-steel fiber exhibited the highest impact resistance, with percentage increases over the other mixtures ranging from 25 to 140%. In addition, the Weibull distribution was used to investigate the cracking impact resistance of UHP at different levels of reliability.

This research focuses on an evaluation of mineral phase and structure transformations in Class F fly ash-based geopolymer systems. The research also studies the strength response of geopolymers when exposed to temperatures between 25 and 800 °C. The purpose of this research is to understand the processes that occur in alkali-activated systems within a wide range of high-working temperatures. The XRD, SEM, and DTA/TG analyses performed for the alkali-activated compositions after exposure to different temperatures confirmed a direct correlation of structural transformations with strength performance. The detrimental effect of sodium hydrocarbonate Na3(HCO3)(CO3) 2H2O or trona contained in one of the fly ash products was observed for the corresponding alkali-activated composite under high-temperature exposure between 600 and 800 °C. It was also detected that a high-temperature interval of 400–800 °C created favorable conditions that helped to form nanosized nepheline crystals and an additional vitreous substance that also contributed to a denser alkali-activated matrix.

The urgency of heat treatment of samples of maraging steel obtained by direct laser deposition from steel powder 06Cr15Ni4CuMo is considered. The structural features and properties of 06Cr15Ni4CuMo steel samples after direct laser deposition and heat treatment are studied. The work is devoted to research into the influence of thermal processing on the formation of structure and the mechanical properties of deposit samples. Features of formation of microstructural components by means of optical microscopy are investigated. Tests for tension and impact toughness are conducted. As a result, it was established that the material obtained by the direct laser deposition method in its initial state significantly exceeds the strength characteristics of heat treatment castings of similar chemical composition, but is inferior to it in terms of impact toughness and relative elongation. The increase in relative elongation and impact toughness up to the level of cast material in the deposit samples is achieved at the subsequent heat treatment, which leads to the formation of the structure of tempered martensite and reduction in its content at two-stage tempering in the structure of the metal. The strength of the material is also reduced to the level of cast metal.

This paper presents a physical and mathematical model that has been developed in the framework of the approach used in the computational mechanics of materials. The model is designed to enable the study of the patterns of deformation and fracture of ceramic composites with a transformation-hardened matrix that are obtained by additive technologies at the mesoscopic and macroscopic levels under intense dynamic loading. The influence of the loading rate on the formation of the fracture and energy dissipation fronts for composite materials, based on the Al2O3 20%ZrO2 system, is shown. Nonlinear effects under intense dynamic loading in the considered composites are associated with the processes of self-organization of structural fragments at the mesoscopic level, as well as the occurrence of martensitic phase transformations in matrix volumes adjacent to the strengthening particles.

A pilot sample of a TiNi-TiB2 metal-ceramic composite has been developed. The sample implements a mechanism of multi-level strengthening using nanosize particles with sizes from tens of nm to 250 nm. The size of the strengthening particles in the micron range does not exceed 5 µm, which ensures their high tensile strength. The authors have developed a computer model of such a metal-ceramic composite that takes into account multi-level strengthening of the TiNi-TiB2 system: the TiNi matrix is indirectly reinforced by nano-sized particles and there is a direct reinforcement by micron-sized TiB2 particles. The authors have performed numerical studies of the mechanisms of deformation and destruction of the metal-ceramic composite with different percentages of content of reinforcing TiB2 particles. It has been demonstrated that a significant contrast between the mechanical properties of the intermetallide TiNi matrix and the reinforcing particles, regardless of the content of reinforcing particles, always leads to the formation of local areas of extension in the metal-ceramic composite. This leads to the destruction of reinforcing particles via the extension mechanism. In the case of high content (57–60%) of micron-sized reinforcing particles, this process of the destruction of strong particles via the mechanism of extension is taking place significantly later at a greater macroscopic deformation of the samples and at greater levels of stress.

This work presents results in the field of synthesis of new metal matrix composites with matrix NiTi and particles TiB2, and their use as additives to fabricate metal matrix composites based on the Inconel 625 alloy. NiTi-TB2 powders were obtained using self-propagating high-temperature synthesis. Composite NiTi-TiB2 particles were spheroidized on a high-frequency induction plasmatron. Composite NiTi-TB2 particles were mixed with metallic Inconel 625 powder with particle sizes of 50–150 µm. We used direct laser deposition by means of mixture of powders to grow samples with different contents of ceramics in the metal matrix. The process of direct laser deposition during the experiment was investigated. We have determined the peculiarities of the formation of the structure in metal matrix composites with different contents of titanium diboride. We have demonstrated the possibility of using Direct Laser Deposition (DLD) for fabricating items from ceramic metal materials. We have determined promising fields of further research for the purpose of obtaining efficient metal matrix composites using additive manufacturing technologies.

This paper explores different modes of synthesis by combustion of chromium-nitrogen and ferrochromium-nitrogen alloys. The SH-synthesis of chromium nitrides and ferrochromium nitrides was performed. Regular patterns in layer-by-layer and surface modes of Cr combustion in nitrogen were investigated. The mechanism of non-stationary combustion during the synthesis of chromium was investigated. Regular patterns of chromium and ferrochromium combustion in the cocurrent filtration mode were analyzed, and the possibility to intensify the SHS process using the pressure filtration principle was assessed. The process of chromium powder combustion in the cocurrent flow of nitrogen-containing gas in the range of specific flow rates from 20 cm3/s·cm2 was investigated. Pressure filtration intensifies the process of combustion wave propagation in the Cr–N2 system. Here, the combustion rate increases while the degree of nitridation decreases. We discovered superadiabatic heating modes when the reaction zone was blown with pure nitrogen and a nitrogen-argon mixture. The tempering mode that was realized during pressure filtration allows for the uptake of high-temperature single-phase non-stoichiometric phases of Cr2N.

A series of casting experiments was conducted with A356 aluminum alloys by applying vibration treatment and using Al-TiB2 composite master alloys. The main vibration effects include the promotion of nucleation and a reduction in as-cast grain size. Using composite master alloys with titanium diboride microparticles allows further reduction in the average grain size to 140 µm. The reasons for this behavior are discussed in terms of the complex effect on the melt, considering the destruction of dendrites, and the presence of additional crystallization centers. Tensile tests were performed on the samples obtained during the vibration treatment and with titanium diboride particles. The tensile strength increased from 182 to 227 MPa after the vibration treatment for the alloys containing titanium diboride.

It has been found that a high electrical conductivity of 63.1%, the International Annealed Copper Standard (IACS), and high mechanical properties are achieved by the initial aluminum alloy after undergoing four cycles of the severe plastic deformation (SPD) process. It has been found that when TiB2 particles are introduced into aluminum and the samples are subject to SPD, the mechanical characteristics of the aluminum alloy are improved. Microhardness (HV) increases from 329 to 665 MPa, yield strength (YS) increases from 38 to 103 MPa, and ultimate tensile strength (UTS) increases from 73 to 165 MPa while maintaining the initial electrical conductivity of cast aluminum without reinforcing particles (53.9–54.1% IACS).

The paper presents microstructure, composition, and burning rate of Al alloy produced by high-temperature synthesis (SHS) from powder mixture Al-Ti-B4C with different concentration of Al powder. It has been established that the phase composition of materials obtained at gas-free combustion includes TiB2, Al, and TiC. It is shown that Al content growth powder in initial Al-Ti- B4C mixture from 7.5 to 40 wt.% reduces the burning rate of the powder from 9*10-3 to 1.8*10-3 m/s. For the system consisting of 60 wt.% of (Ti + B4C) and 40 wt.% of Al there is the increase in the porosity of the compacted initial powder mixture from 30 to 51 and reduction in the burning rate from 1.8 * 10-3 to 1 * 10-3 m/s.

The paper studies dispersion, oxidation degree, burning rate and combustion heat in high-energy mixtures obtained from of Al-Mg powder materials depending on the duration of mechanical activation in a planetary mill. According to dispersion analysis by laser diffraction method, 3 h mechanical activation gives Al-Mg particles with average particle size of 30 μm compared to 180 μm particles obtained after 2 h activation. Thermogravimetric analysis (TG) and differential scanning calorimetry (DSC) were used to record TG/DSC curves and measure burning rate and combustion heat for synthesized powders in comparison with engineered Al-Mg powder PAM−4 (Novosverdlovsk Metallurgical Company, Yekaterinburg, Russia). It has been found that the injection of 6 h mechanically activated Al-Mg powder into high-energy compositions leads to 24 and 45% increase of burning rate and combustion heat compared to the compositions without additive.

The results of an experimental investigation performed in this study allow supposing that a change in the aggregate state (crystallization) of a substance on the surface of the introduced small-sized (nano- or submicron) particles significantly affects the grain size in the final states of the alloys and composites. This is due to the fact that the melt – particle system is found in a low-stability state, hence even weak thermal actions of the inoculators-microparticles can influence the final state of the alloy, both its structure and physical-mechanical properties. As a result of thermal interaction between the particle and the melt, whose temperature is close to that of the change of the aggregate state (crystallization), the metal on the surface of the particle changes its aggregate state. A thermal model of the change of the aggregate state of a substance proposed in this study makes it possible to predict the velocity and degree of local cooling of the melt, the crystallization time, and the minimal size of the resulting crystallites as a function of the particle dispersion and mass concentration. The smaller the size of the particles and the higher their mass concentration, the smaller the grain size in the final alloy. The full-scale experiment verified the principles obtained in the thermal model: the smaller the size of introduced particles, the smaller the grain size of the final alloy. The average grain size of the initial technical-grade aluminum was ~1200 μm. Upon introduction of 0.2 wt.% of composite SHS-master alloys of the Al–Ti–B4C system (average particle size 0.4 μm) the average grain size of the alloy was found to be 410 μm. Upon introduction of 0.2 wt.% of composite SHS-master alloys of the Al–Ti–B system (average particle size 0.7 μm) the average grain size of the alloy was found to be 540 μm.
