There were submitted findings of investigations related to fusion process of high-dispersive powder Cr3C2 and analysis of its characteristics. Chromi- um carbide was obtained by means of carbothermal reduction Cr2O3 by nanofibrous carbon in an atmosphere of argon. Obtained specimens were investigated by means of X-ray phase, X-ray fluorescence, picnometer and thermal analysis, as well as scanning electron microscopy. Content of to- tal carbon was determined by means of specimen burning under oxygen, with subsequent CO2 detection. Specific surface (Ssp = 1,0÷1,2 m2/g), pore space (0,002-0,003 cm2/g) and its diameter (d ~ 12 nm) of specimens Cr3C2 were determined by means of BET-method. There was established that ob- tained chromium carbide consist of particles with size predominantly of 3–5 μm. Start of oxidation of chromium carbide depending on temperature occurred in the range t = 565÷610 °C, and at obtaining temperature of 1100 °C it is oxidized almost completely. 

There was investigated influence of mechanical activation in centrifugal planetary mill (during 9–43 min at relation of balls mass and material B : M = 20 : 1) and subsequent high-speed heating (~ 6 °C/s) on phase formation in the system of chromium–carbon. There was elucidated that incu- bation period of carbide forming during mechanosynthesis process correlated well with thinning of interlayer of chromium in rolls like particles until length of chromium’s diffusion path into carbon. There was demonstrated that not occurred any sufficient (> 1 kJ/mol) internal energy storage in the lattice of crystalline chromium and free surface of soot. There was confirmed diffusion character of carbide forming in the system of chromium – soot as in mechanosynthesis process, both at subsequent flash heating. 

There was determined square area of dendtitic zinc deposits obtained by means of electrolysis from zincate electrolyte with 0,3 mole/dm3 of ZnO and 4 mole/dm3 of NaOH. The application of electrochemical methods allows to measure square area in situ without removal of dendritic deposit from cathode. Deposit specific surface area determined with the aid of chronopotentiometry method makes up 0,144 ± 0,002 m2/g, and 11,61 ± 0,14 m2/g in accordance with impedance spectroscopy. The square area of powders obtained from dendritic deposits was equal to 21,26±0,62 m2/g in accordance with data of BET method. There was demonstrated that surface of dendritic deposits have fractal properties. There was computed fractal dimension of specific surface area, and with the aid of scaling ratio was made comparison of measurement findings, obtained by means of different methods 

There was investigated the structure of native crystalline and crypto-crystalline graphite from Krasnoyarsk Krai’s deposits with the aid of X-ray analy- sis on diffractometer «Bruker» D8 ADVANCE. There were revealed alterations of types and parameters of crystal lattice by means of mechanical ac- tivation or mechanical synthesis of material, and was established optimal performance of graphite activation by which these alterations occurred. There was considered influence of time activation on parameters of structure of both types graphite. There was demonstrated that at optimal ac- tivation time of graphite occurred improving of its physical and chemical properties due to alteration of type and parameters of lattice and amor- phization of crystalline lattice. 

There were introduced shrinkage curves of alloys obtained from hard-alloy mixtures based on WC-8%Ni, activated by means of introduction of 10 % nano-sized WC, and charging material without additives over the ranges of temperature 800–1500 °C. There was investigated pore structure and microstructure of specimens on the different stages of sintering. There was uncovered peculiarity of modified alloy’s compression that involves disalign- ment of shrinkage curve in field of more low temperatures. This is allows decrease temperature of its vacuum compression sintering, obtain more fine- grained structure and attain high indices of hardness/enduring quality, without decreasing of strength characteristics. There were investigated physi- cal and mechanical properties and microstructure of compression sintering specimens from activated alloy VN8M and standard VH8 without additives 

There was conducted investigation of physical and chemical properties and structural constituents of calcium hydride intermetallide TiNi. There were examined peculiarities of influence of different kinds of consolidation (hot isostatic pressing and hydrostatic pressing with subsequent sintering in vacuum) on chemical and phase composition of compacts from examined powders by means of optical spectrometry and scanning electron micro- scopy, X-ray structural analysis and analysis of gaseous elements. There was established that sintering in vacuum allows decrease content of gaseous oxygen, nitrogen, and particular hydrogen. 

There were considered the main methods of powders WC production: rapid carbothermal reduction (RCR), «calcination – reduction – carbidization» (CRC), reduction of tungsten oxide by carbon at rotary furnace, method of spray conversion process (SCP), self-propagating high-temperature synthesis (SHS), high energy milling and others. There was made analysis of impact of growth inhibition for carbide grain on structure of hard alloys. According to the data of some authors, optimal content of inhibitor is equal to 0,5–1,5 mas.%; in the case of its large quantity has place brittleness of alloy by means of formation of complex carbide phases. There was demonstrated that is impossible obtain nanosized hard alloys (dWC < 100 nm) by means of traditional solid-state sintering of mixtures – it is need to use alternative solid phase consolidation. There was considered structure, properties and fields of application submicron and nano sized hard alloys, obtaining by means of hot pressing, high frequency induction pressing, electric discharge sintering during plasma pressure consolidation (PPC), spark plasma sintering (SPS) etc. 

Made analysis of special peculiarities and regularities of reactions of titanium carbide, alloyed on metalloid sub lattice (N, O) with nickel melt. There was established that partial replacement of carbon in TiC on nitrogen decreases velocity of it dissolution in nickel, and increases degree of incongru- ence of process (preemptive, in comparison with titanium, transition into carbon melt). Concentration dependence of dissolution rate TiCxNz in nickel changes their sign on opposite with approximation of system to equilibrium. Carbonitrile of titanium as single phase is not recrystallized through nickel melt, dominantly has place recrystallization of its carbide constituent. There was elucidated that partial replacement of carbon in TiC on oxy- gen increases velocity of its dissolution in nickel. Process of dissolution of oxycarbide TiC0,6O0,4 in nickel is accompanied by graduate loss of it carbon, up to formation of titanium mono oxide, and further its disproportionation. Peculiarity of interaction mechanism of titanium oxycarbide with nickel melt is determined by reaction in liquid phase [C] + [O] = CO . 

There was discoursed procedure of carrying out of virtual experimental works on assessment of the main material functions, that defining plastic current of porous materials: function of density of ellipsoidal surface of loading and dependence of yield stress on deformation. The procedure is based on creation of finite element model of representative volume (a material point) of porous body with casually distributed empty finite elements that imitated properties of porous, and was approved by means of carrying out of physical and virtual experiments. Obtained data of comparison of experimental findings give ground to recommend the new procedure instead of experimental studies of mechanical properties of porous materials. 

By means of optical interferometry, scanning electron microscopy and X-ray phase analysis was examined surface topography, peculiarities of struc- ture and phase composition of coatings in the system TiB2–Al, obtained by electroexplosive sputtering. There was established that after treatment parameter of surface irregularity Ra = 2 μm. Phase composition of formed layers includes Al, TiB2 and TiBO3. Coatings have cohesive-adhesive bind with material of contact surface. 

There was considered influence of cyclical variation of temperature (from –60 °C to +60 °C) and duration (1000 h) of thermal impact (+60 °C) on adhesive strength and resistance to direct stroke of paint coating. There were concluded the main regularities and made practically meaningful conclusion on uselessness of application of testing data for assessment of inner corrosion-resistant coatings of oil and gas pipes.
