The influence of particle size distribution of exothermic mixtures of silica filler on the basis of their turnover has been studied. The optimization of particle size distribution of mixtures will reduce the dropout process step fine fraction 0.2 - 0 mm, which greatly simplifies and reduces the cost of technology. The…
In this paper a numerical-analytical study on a stress-strain state of a steel pipeline section with a repair fiberglass viscoelastic layer is described. The layer is considered long enough that allows to solve the problem in a flat axisymmetric statement. A mathematical model of viscoelastic behavior of a fiber-glass…
Представлен механизм эволюции структуры дисперсной фазы пластичного смазочного материала в процессе трибовзаимодействия пары трения. Показано, что разрушение пластичных смазок, модифицированных наноразмерными добавками, происходит на более поздних стадиях трибоконтакта по сравнению со стандартными смазками и обусловле…
Experimental verification of the validity of the discovered effect of the increase of density of metals being electrodeposited under the influence of a centrifugal force directed perpendicular to the crystallization front is fulfilled. The decrease of the intensities of X-ray diffraction maximums and lowering of poros…
A review and analysis of papers describing the results of fabrication and testing of various shapes of the composite end-domes for underwater pressure hulls was carried out. The aim of the paper is to evaluate the prospects for the use of FRP as constructional material for the various shapes of shell structures used i…
The connection between structural zones of steel castings and their dendrite and grain structure is studied. It was demonstrated that the direction of dendrites, being the result of crystallization, determines the direction of grain boundaries formation in cast steel. Grain morphology, size and peculiarities of their…
Based billing model of the dynamics of elements of a design of aircraft engines in the field of acoustic radiation of a high level. The task of establishing local peculiarities perturbed motion of components on the profile level. Substantiated the validity of the analysis on the estimated model thin isotropic plate, s…
In this study, a small heat shock protein tpv-Hsp14.3 from a thermoacidophilic Archaeon, Thermoplasma volcanium was studied. sHSPs are low molecular weight proteins involved in different stress responses to protect the cellular proteome and enhance survival of the host organism. For structure-function analysis of the…
The features of structure formation and mechanical properties of austenitic- ferritic steel 03Kh13N10K5M2Yu2T have been studied at different stages of thermoplastic processing. The technology has been developed and the reasons of formation of high-strength condition had been analysed.
A new approach to the design of installations of the combined process of continuous casting and deformation, including the study of the stress-strain state of the metal in the deformation zone, the solution of the optimization of technological and structural parameters of the installation and computer-aided design.
Operating home and foreign standards are analysed as evaluated by a graining structure. The new methods of analysis and reconstruction of structuThe computer program STRUCTURA-2001, allowing in number to estimate the structure of metals and alloys, is worked out.
The perspective flow sheets of receipt of purveyances of shoulder-blades of GTE are considered from the alloyed titanic alloys. It is shown that application of chart of intensive compression of metallic powders, allows to get shoulder-blades possessing enhance able technical and economic indicators
The peculiarities of the choice of the engine type for different transport facilities, operation conditions and also the estimation of their efficiency have been described. The efficiency criteria of the transportation facilities during the optimization of their engines have been analyzed. The applicability of some an…

The article considers the problem of defining a number of advantages and key moments for ultrasound clearing of parts in Freon-compositions. The designs of ultrasound units, used in the earlier production, are proposed. The comparative identification of cleaning mixtures in regard to their components is conducted. The…
The calculations of the electromagnetic, hydrodynamic and temperature fields crystallized melt with diameter 163 mm. Obtained full picture of the dynamics of crystallization. Calculated speed of crystallization of the different layers of the metal melt.
The progress of inorganic chemistry is syntheses of new triple phosphates Ca 9 CoM(PO 4 ) 7 (M = Li, Na, K) were synthesized by solid state method. Their crystal structures were determined by Rietveld analysis. They are related to tricalcium phosphate and crystallize into trigonal system (space group R3c) with unit-ce…
