Wet magnetic separation of Siberian iron-ore concentrates / E. K. Yakubailik [et al.] // Steel Transl. - 2014. - Vol. 44, Is. 2. - P. 113-116, DOI 10.3103/S096709121402020X. - Cited References: 3 . - ISSN 0967-0912. - ISSN 1935-0988

concentrate -- ore -- wet magnetic separation
Аннотация: Wet separation of the primary Siberian iron-ore concentrates processed at Abagursk enrichment facility (OAO Evrazruda) is studied in the laboratory. Nine samples of concentrates (-0.07 mm class) from magnetite ore and weakly oxidized ore are subjected to wet magnetic analysis in a field of 80 kA/m. The basic magnetic characteristics of the initial concentrates and the products obtained on separation are measured. The yield of magnetic product is greatest for magnetite ores: more than 68% (Abakan), as compared to 43-45% for weakly oxidized ore. Thus, the yield of magnetic product falls with decrease in magnetite content in the initial material. The following practical recommendations are offered: (1) it is expedient to enrich weakly oxidized ore after mixing with magnetite ore, so as to reduce the loss of iron with the tailings; (2) the magnetic systems of PBM 90/250 separators must be reconstructed, with the introduction of stronger magnets. © 2014 Allerton Press, Inc.

Аннотация: The aim of the work is to elucidate the origin of magnetization presence in austenitic Fe86Mn13C steel after dynamic loading. The observation of microstructures in the region of transition from FCC austenitic Fe86Mn13C steel to FK12 + FK14 type of Frank-Kasper tetrahedral close packed structure is described. We used the methods of optical microscopy, electron microscopy, electron diffraction and X-ray-diffraction to investigate the phase transition region. Changes of local magnetization were estimated by induction method. To explain the magnetization origin of the sample consisting of austenite grains and intergranular layers, which have Frank-Kasper's structure (FK12 + FK14) typical of beta-Fe-Mn, the local electronic structure has been investigated for intergranular layers. The local electron structure of FK12 and FK14 clusters have been simulated by method of self-consistent field to understand the nature of non-zero magnetization of the Fe87Mn13 alloy exposed by shock deformation. It was shown, that numbers of states with upward and downward spins are not equal. Therefore the occurrence of magnetization is possible. (c) 2009 Published by Elsevier Ltd

Losses of magnetite iron in wet separation / E. K. Yakubailik [et al.] // Steel Transl. - 2016. - Vol. 46, Is. 6. - P. 390-394, DOI 10.3103/S0967091216060115. - Cited References: 15 . - ISSN 0967-0912
Кл.слова (ненормированные):
high-power magnets -- iron losses -- magnetic parameters -- magnetite iron -- tailings -- wet separation
Аннотация: Samples of all the tailings from enrichment processes at the Abagur plant operated by OAO Evrazruda are studied. The tailings are subjected to magnetic and chemical analysis, and the magnetic characteristics of the products are measured. The mean magnetite iron content in the tailings was about 0.9% in 2013. Experiments confirm that the main magnetite losses are associated with small classes and their poor magnetic properties. The losses of magnetite are reduced as the separation field is increased. At the plant, 45% of the barium–ferrite magnetic systems in the PBM 90/250 separators have been replaced by a system based on neodymium–iron–boron composites, with increase in the field from 111 to 175 kA/m. Modernization of the magnetic systems in all the separators at the Abagur plant is recommended. In thickening, the installation of separators for regeneration of the suspensions, with a field of 190 kA/m, is recommended. After reconstruction, the losses of magnetite iron at the plant may be reduced to 0.45–0.55%. © 2016, Allerton Press, Inc.

Optimization of steel-surface hardening by carbon nanostructures followed by treatment with hIgh-intensity energy sources / G. S. Bocharov [et al.] // J. Surf.

Кл.слова (ненормированные):
metal surface hardening -- carbon nanomaterials -- laser irradiation -- electron-beam treatment -- microhardness
Аннотация: The effect whereby a steel surface is modified by its covering with a nanocarbon material followed by fast electron- or laser-beam irradiation is studied. The initial material is low-carbon steel. Soot produced via the thermal sputtering of graphite electrodes in an electric arc with the subsequent extraction of fullerenes is used as the nanocarbon coating. Due to the fact that nanocarbon-coated samples are irradiated with a 60-keV electron beam, the material microhardness enhances considerably. The dependence between the microhardness and the irradiation energy is nonmonotonic and reaches its maximum (about 600 ± 20 HV) under the condition that the electron-irradiation energy is 460 J/cm2 and the intensity is 1.53 kW/cm2. This corresponds to a fourfold increase in the microhardness. Electron-beam irradiation of the treated surface is accompanied by a 1.5–2-fold decrease in the friction coefficient. Experimental results are compared with data obtained under laser irradiation of the nanocarbon-coated steel surface.

Microstructure of intercritical heat affected zone and toughness of microalloyed steel laser welds / L. S. Derevyagina [et al.] // Mater. Sci. Eng. A. - 2020. - Vol. 770. - Ст. 138522, DOI 10.1016/j.msea.2019.138522. - Cited References: 28 . - ISSN 0921-5093
Кл.слова (ненормированные):
Low-carbon steel -- Laser welding -- Heat affected zone -- Structure -- Toughness
Аннотация: Microstructure of laser welds of the X70 low-carbon pipe steel was studied. High cooling rates after laser welding and non-uniform distribution of carbon in the ferrite-pearlite base metal caused formation of regions with increased microhardness (up to 650 НV) in inter-critical heat affected zone (ICHAZ). These regions consisted of finely dispersed degenerate upper bainite and martensite-austenite constituents of a slender shape and small fraction of a massive shape along the boundaries of bainite laths, as well as twinned martensite. High concentration of martensite-austenite constituents (10–16%) and residual stresses in ICHAZ, as well as a dendritic martensitic structure with carbide interlayers along the boundaries of martensite laths in fusion zone were the main reasons of sharp decrease in charpy impact energy of the welded samples. High microhardness of the laser welds was decreased down to 320 HV and their brittleness was improved by annealing. Also, in ICHAZ, degenerate upper bainite and the regions of martensite-austenite constituents decayed forming tempered sorbite and Fe2C and Fe3C carbides, respectively. Charpy impact energy of the welds doubled after annealing compared to the welds without annealing, and ductile-brittle transition temperature decreased down to –60°С.

Low-carbon steel -- Cross-helical rolling -- Laser welding -- Heat affected zone -- Bainite -- Microhardness
Аннотация: In this paper, the heat affected zone (HAZ) of laser welded joints of the X70 steel were studied by the transmission electron microscopy method. The effect of the initial microstructure (coarse-grained hot-rolled and fine-grained after cross-helical rolling) on the HAZ formation and the mechanical characteristics of the welded joints were shown. It was found that the microstructure in the inter-critical HAZ of the steel after cross-helical rolling was more dispersed, homogeneous, and uniform compared to that of the coarse-grained hot-rolled one due to the initial fine-grained ferrite-bainitic-pearlite microstructure and the absence of pronounced ferrite-pearlite banding in the base metal. The character of the microhardness value distribution in the HAZ of the steel after cross-helical rolling was smooth with the gradual decrease from 370 down to 185 HV as shifted towards the base metal. In the HAZ of the coarse-grained hot-rolled steel, the heterogeneous microhardness value (up to 640–670 НV) distribution was revealed. The reason was the upper degenerate bainite microstructure with high residual stresses, characterized by laths up to 2.0–2.5 μm long and a high martensitic-austenitic constituent fraction (10–16%) of a slender shape along the boundaries of bainite laths. The conclusion was drawn that one of the ways to reduce the brittleness of the laser welded joints could be using the initially fine-grained steels possessing the homogeneous (mainly bainitic) microstructure.

Effect of helical rolling on the bainitic microstructure and impact toughness of the low-carbon microalloyed steel / L. S. Derevyagina, A. I. Gordienko, N. S. Surikova, M. N. Volochaev // Mater. Sci.

Кл.слова (ненормированные):
Low-carbon microalloyed steel -- Helical rolling -- Microstructure -- Bainite -- Martensite–austenite constituent -- Impact toughness
Аннотация: Ferrite-bainite microstructures and impact toughness of the X65 low-carbon microalloyed steel were investigated after helical rolling at 1000, 920, 850, and 810 °C followed by continuous cooling in air. After helical rolling at 1000 °C, granular bainite with large areas of the massive-shape martensite-austenite constituent (d = 1.5 μm) and a high fraction of twinned martensite (d › 2.0 μm) were observed in the steel. This caused a decrease in impact energy at low test temperatures (for example, 70 J at –70°С). Lowering the helical rolling temperature contributed to a reduction of dimensions of both ferrite-bainite and martensite-austenite constituent areas, as well as the replacement of the latter by a slender type one and an improvement in fracture toughness at the low temperatures. The highest impact energy level (210 J at –70 °C) was achieved after helical rolling at 850 °C due to the formation of a homogeneous microstructure, which included dispersed ferrite grains, granular bainite and small fractions of the slender type martensite-austenite constituent (d = 0.1–0.7 μm). In this case, areas of twinned martensite were absent.

high-nitrogen steel -- austenite -- ultrasonic forging -- electron beam treatment -- aging -- CrN -- strength -- plasticity
Аннотация: The structure and mechanical properties of austenitic high-nitrogen steel (16.5 Cr, 18.8 Mn, 0.07 C, 0.53 N, 0.52 wt % Si, Fe for balance) have been investigated after severe deformation–heat treatment, which has involved shock surface forging at the ultrasonic frequency (USF) and electron-beam heat treatment (EBT). A subgrain structure hardened by CrN nanoparticles has been shown to form in the surface layer as a result of deformation–heat treatment. No discontinuous decomposition of austenite with the formation of Cr2N nitrides takes place. This structure modification in the surface layer enhances the strength properties of the steel, namely, σ0.2 increases to 712 MPa and σu to 923 MPa at a plasticity of 25%. The yield strength increases by 50% compared to the state after quenching.
