Radiation hardening of constructional cement–magnetite–serpentinite composite under gamma irradiation at increased dose
Inorganic Materials: Applied Research - Tập 8 - Trang 691-695 - 2017
R. N. Yastrebinskii, G. G. Bondarenko, V. I. Pavlenko
It is shown that a constructional radiation-shielding composite material with high resistance to radiation-thermal loads can be obtained. The material was produced using a Portland cement mix, boron-containing chrysotile, magnetite filler, plasticizing additives, and metal fraction by the vibro-packing method. The content of chemically bound water was at least 1.5 wt %. Exposure to high doses of g...... hiện toàn bộ
Gradient Structure Generated in Hardox 450 Steel with Built-Up Layer
Inorganic Materials: Applied Research - Tập 9 - Trang 427-432 - 2018
S. V. Konovalov, V. E. Kormyshev, V. E. Gromov, Yu. F. Ivanov, E. V. Kapralov
This article investigates the phase composition and the defect substructure of a modified layer built up on Hardox 450 steel by wire containing C, Mn, Si, Cr, Nb, W, and Fe. It is established that, upon surfacing, a high strength surface layer with increased microhardness is formed. Using transmission electron microscopy, it is demonstrated that strengthening of the surface layer can be attributed...... hiện toàn bộ
Bioactive ceramic composite materials in hydroxyapatite-tricalcium phosphate system
Inorganic Materials: Applied Research - Tập 1 - Trang 182-187 - 2010
O. L. Kubarev, V. S. Komlev, S. M. Barinov
Materials in hydroxyapatite-tricalcium phosphate systems are promising for the use in cell technologies for regeneration of damaged bone tissue. The results of investigations of the influence of the synthesis conditions on the phase composition of materials and the formation of their structure and properties upon baking of powders are given. The parameters of the process of preparation of material...... hiện toàn bộ
Layered Double Mg–Al Hydroxides to Dephosphate Municipal Effluents
Inorganic Materials: Applied Research - Tập 12 - Trang 1257-1264 - 2021
T. T. Gorbacheva, D. V. Mayorov, N. V. Fokina
The phosphate recovery process is simulated to explore the potential of phosphate recovery from model solutions and from a sludge mixture in the regional sewage treatment plants. Layered Mg–Al double hydroxides (LDH) obtained through a solid-phase synthesis according to a proprietary process are used as sorbents. Experimental results on ...... hiện toàn bộ
Development of the plasma technology for the production of uranium oxides with a given oxygen coefficient for the fabrication of pelletized nuclear fuel
Inorganic Materials: Applied Research - Tập 6 - Trang 205-211 - 2015
Yu. N. Tumanov, N. V. Dedov
The process of uranium reduction via plasma denitration of uranyl nitrate solutions in a plasma reactor of a nuclear-safe geometry with the use of soluble reducing agents (carbamide (NH2)2CO, sucrose C12H22O11, and acetic acid CH3COOH) is studied. Dispersed uranium oxide with the required oxygen coefficient (2.1–2.3) is obtained. It is found that acetic acid is the optimum reducing agent, and the ...... hiện toàn bộ
Durability evaluation method for vessel internals of VVER by criterion of initialization of intergranular stress corrosion cracking of irradiated austenitic steels
Inorganic Materials: Applied Research - Tập 2 - Trang 624-632 - 2012
B. Z. Margolin, V. A. Fedorova, V. M. Filatov
A physicomechanical model for occurrence of fractures of austenitic steels upon intergranular stress corrosion cracking (IGSCC) is proposed on the basis of an analysis of experimental data on the susceptibility of irradiated austenitic steels to IGSCC during contact with the coolant of the primary circuit of a water-moderated water-cooled power reactor (VVER). A durability evaluation method for un...... hiện toàn bộ
Change in magnetic properties of superconducting ceramics under ion irradiation
Inorganic Materials: Applied Research - Tập 2 - Trang 210-211 - 2011
S. V. Simakov, Yu. Jiao, M. Zheng, N. A. Vinogradova
The effect of irradiation with 48-MeV argon ions on the magnetic properties of high-temperature superconducting ceramics of the GdBaCuO system is studied. It is shown that ion irradiation with a dose up to 5 × 1011 cm−2 leads to an increase in the magnetization hysteresis of the ceramics.
On the Problem of Roadmapping of Domestic Arctic Materials Science: Part I
Inorganic Materials: Applied Research - - 2018
V. M. Buznik, N. P. Burkovskaya, I. V. Zibareva, R. N. Cherepanin
The current state of domestic Arctic materials science (AMS) is considered using bibliographic analysis of publications by the CAPlus database and expert assessments by the Delphi method. The results obtained are intended for use in the construction of a Roadmap for the Development of Domestic Arctic Materials Science.
