Control over the reagent mode of flotation of copper-nickel ores
Allerton Press - Tập 53 - Trang 116-119 - 2012
Control over the reagent flotation mode of copper-nickel ores is considered. It
is proposed to take into account the residual concentration of sodium dimethyl
dithiocarbamate (DMDC) ions in the pulp in its algorithm. Controlling the DMDC
consumption using the results of determining the residual concentration of its
ions in the pulp optimizes the reagent mode and makes it possible to increase
the q...
Deposition of coke particles in the liquid pitch-coke composition of the soderberg anode
Allerton Press - Tập 50 - Trang 606-609 - 2010
Investigations performed an anode of the aluminum electrolyzer, showed the
nonuniformity of coke particles in regards to the height of the region of the
pitch-coke composition. This is associated with the sedimentation of coarse
fractions of the coke charge in a viscous medium. The sedimentation of coarse
coke particles is investigated in laboratory conditions for the model of liquid
pitch-coke co...
Features of combustion in the Mo-Si-B system: Part 2. Effect of mechanical activation
Allerton Press - Tập 56 - Trang 307-312 - 2015
This study is devoted to investigating the effect of mechanical activation (MA)
on the kinetics and combustion mechanism of a reaction mixture in the Mo-Si-B
ternary system, as well as ceramic material production by the self-propagating
high-temperature synthesis (SHS) method. Elemental molybdenum, silicon, and
boron powders are used as the initial components. The MA was carried out in a
planetary...
Plastic properties of homogenized coke-pitch compositions
Allerton Press - Tập 52 - Trang 205-208 - 2011
The rheological properties of coke-pitch compositions are investigated after
their mechanical activation (MA) treatment in the hydroblow-cavitation field for
three compositions of a coke charge containing finely dispersed coke fractions.
The rheological properties of these mixtures are compared with those not
subjected to MA. It is established that, as a result of MA, plastic viscosity
decreases. ...
Calculation of the yield point of silumins by the characteristics of their structure
Allerton Press - Tập 50 - Trang 234-241 - 2009
A model is constructed showing the possibility of calculating the yield point by
the structural characteristics of alloys of the Al-Si-Cu and Al-Si-Mg systems in
natural and artificially aged states. This model possesses good prediction
ability at copper concentrations up to 5%, magnesium up to 1%, and silicon up to
11% at an aging temperature of 140–220°C and a holding time of up to 100 h. The
ma...
Elemental composition, topography, and wettability of the surface of graphite modified by ion-assisted deposition of chromium coatings
Allerton Press - Tập 49 - Trang 303-307 - 2008
Elemental composition, roughness, and wettability of a graphite surface modified
by ion-assisted deposition of a Cr coating ∼300–1000 nm thick are investigated
using the methods of Rutherford backscattering, atomic force microscopy, and
contact angle measurements. It is established that, in addition to chromium,
coatings involve hydrogen, carbon, and oxygen from residual gases of a vacuum
chamber ...
Improving the Casting Process in Ceramic Forms Using Additive Technologies in Manufacturing Model Kits
Allerton Press - Tập 62 - Trang 675-681 - 2022
The free linear shrinkage of samples from PLA, HIPS, and ABS filaments, used for
3D printing by FDM technology in extrusion operating temperature ranges, has
been studied. It is found that the PLA filament is characterized by shrinkage
values in the range of 0.2–0.6% in operating extrusion temperatures of
200–220°C. HIPS filaments (operating temperature range of 220–240°C) and ABS
filaments (opera...
Investigation into the Structure and Oxidation Mechanism of FeAlCr/Al2O3 Detonation Spraying Coatings
Allerton Press - Tập 60 - Trang 207-214 - 2019
The oxidation resistance of detonation spraying coatings of the FeAlCr/Al2O3
powder fabricated by mechanically assisted self-propagating high-temperature
synthesis using aluminothermic reactions of oxide reduction is investigated. The
powder has a sufficiently homogeneous composite structure consisting of
chromium-alloyed ordered B2-FeAl and fine inclusions of α-Cr2O3 and α-Al2O3. The
detonation c...
Viscosity of high-entropy melts in Cu-Sn-Pb-Bi-Ga, G-Sn, Cu-Pb, Cu-Ga, and Cu-Bi equiatomic compositions
Allerton Press - Tập 56 - Trang 246-250 - 2015
Temperature dependences of kinematic viscosity of high-entropy melts (HEM) of
the composition, at %, Cu-20Sn-20Pb-20Bi-20Ga, Cu-50Sn, Cu-50Pb, Cu-50Ga, and
Cu-50Bi are investigated in a temperature range from 1550 to 1300°C. It is shown
that melt overheating above a definite temperature (t hom) leads to the
appearance of viscosity hysteresis, which indicates a variation in the
structural state of ...
Development and Experimental Testing of the Technology for Producing Deformed Bars of Alloy D16T from Continuously Casting Billets of Small Diameter with Low Elongation Ratios
Allerton Press - Tập 63 - Trang 328-335 - 2022
The article describes the development and pilot-industrial testing of the
technology for producing bars from aluminum alloy D16T obtained by radial-shear
rolling (RSR) from continuously cast billets (CCB) with a diameter of 72 mm in
several passes. The actual dimensions of the rolled bars were within ±0.16 mm
for all bar diameters, which is significantly less than the diameter tolerance
stipulated...
