Laboratory training and student research work are exceptionally important components characterizing the level and efficiency of engineering education. The use of information and communication technologies enables the increase in the number of laboratory installations available for training students. Bauman University has provided the unique equipment which was used as a basis for remote access laboratories...
With the adaptation of Internet by countries around the world considerable efforts had been made to transfer the knowhow via online from socalled developed countries to developing and emerging countries. Such e-education is especially true for specified types of education material, such as the ones on technical and medical fields. In highly advanced fields, e-education provides a cost effective and...
On behalf of the Mongolian University of Science and Technology and as the Chairman of the 8th International Forum on Strategic Technology (IFOST2013), I feel deeply honored to welcome all the distinguished guests, speakers and participants of the Forum such as scientists, specialists and students from University of Ulsan (South Korea), Novosibirsk State Technical University (Russia), Tomsk Polytechnic...
We have obtained zinc oxide (ZnO) in the form of nanocrystallites with crystallite sizes from 46 nm to 3 nm by milling 1.4 micron ZnO powders in the high energy ball mill (HEBM) for the different times: 1, 5 and 8 hours. Crystal structure changes of the ZnO nanocrystallites were studied by x-ray diffraction techniquies. It was established appearance of two new phases: pure zinc (Zn) and cubic zinc...
Microstructure and mechanical properties of copper and tantalum joints produced by explosive welding technology were characterized. It was established by structural analysis technique that mixing of copper and tantalum at the interface occurs due to a nonequilibrium process. The mixing zone consists of tantalum globular particles which sizes vary from 8 to 40 nm. In the close vicinity to the interface...
Magnesium alloy and aluminium alloy are the promising structural light metals. The demand for magnesium alloy and aluminium alloy are increasing rapidly. A large amount of waste in the form of chips and scraps is produced in the manufacturing process such as die casting and plastic forming. In this paper, a method for recycling magnesium alloy and aluminium alloy chips or scraps directly by solid...
A study has been made on the polarization dependence and the temperature dependence of absorption and luminescence spectra of a 2,6-dihydroxyanthraquinone single crystal. The single crystal structure has been investigated by X-ray diffraction and is assigned as monoclinic and the space group P21/c (#14). Electronic energy levels were calculated by molecular orbital calculation program of WinMOPAC...
Two kinds of the transparent ceramics have been investigated in this work: magnesium aluminate spinel MgAl2O4 and yttria-stabilized zirconia ZrO2-3mol.% Y2O3 (YSZ). Optical and mechanical properties of transparent ceramics versus conditions of spark-plasma sintering (SPS) have been investigated. SPS modes have been studied at different heating duration, pressure force. Behavior of transparency, density,...
This research presents a new die on principle of the collector method. The collector die of spiral type for uniaxial dry compacting homogeneously dense powdered bodies of complex shape without macroscopic defects has been developed. To reduce the die-wall friction effects collector method is based on the self-alignment of uniform density regions within a green compact. The purpose of this work is...
The metal porous body has interesting structural characteristics such as high specific strength and lightness and high antivibration, damping and sound absorption properties and also has excellent functional characteristics such as unique thermal insulation and catalytic carrier absorption and so on. With these advantages, recently, it has been using a high performance lubricant bearing, filters for...
Gas atomization is the conventional and well-known methods to produce metal powders. This method can be used to get high sphericity and fluidity of the powders. The metal powders produced by the gas atomization have a rapid cooling rate because of fast heat transfer between the droplets and the injected gases. The gas atomization can be used to produce various metal powders with melting temperatures...
Commercial nanopowder of the partially yttrium-stabilized zirconia (ZrO2+3mol.% Y2O3) was treated by the non-cavitational powerful ultrasonic action (PUA). Influence of PUA on the microstructure and phase composition of the powder has been investigated by scanning and transmission electron microscopy. Investigated powder before and after PUA has polycrystalline structure. It was found that TZ-3YS...
Experimental methods for aluminum nitride rate increase at combustion of aluminium nanopowder in air, such as increase of aluminum nanopowder sample mass, air volume limitation, etc. are examined in the paper. The influence of infrared radiation on aluminium nanopowder and its mixtures samples on aluminum and titanium nitrides rate in combustion products was experimentally investigated in the work...
It has been found that metal nanopowders produced by wire electrical explosion have stored energy, which is higher than the standard heat of melting. Continuing studies on stored energy the influence of electrons flow (accelerator ELU-4) on iron and nickel nanopowders has been investigated in the paper. It was found that the thermal effect of oxidation for iron nanopowders after exposure increased...
