Abstract:
Processes of lining erosion and scull formation effect considerably the blast furnace (BF) campaign duration. Among factors, influencing the processes, impacts are distinguished, stipulated by the kind of smelted product as well as materials used for scull formation. In the BF No. 2 of Kosaya Gora steel-works within the campaign from October 1999 until November 2015, 930,000 t of high-carbon ferromanganese (mainly ФМн78 grade) and 110,000 t of foundry iron were produced. After it stoppage for overhaul, samples of the scull were picked out and studied. It was revealed, that the scull of walls of BF hearth has a laminated structure and consists of crystallization products of metal and slag melts, namely: graphite, iron carbides, manganese carbides, iron, ferromanganese, slag components. At the macro level the scull has a lamellar structure. Since during the last campaign the blast furnace apart from ferromanganese was smelting foundry iron rather long time, in the samples, picked out at the level of iron notch at some distance from the cooler, the scull metallic phase mainly consisted of iron and iron carbide. In the sample picked out at a big distance from the cooler, in the scull metallic phase the following phases were discovered by X-ray structural and Moessbauer methods: ferromanganese; complicated manganese and iron carbides, as well as α-iron. Quantity of slag components in the scull decreases in direction from iron notch level to the hearth that speaks about splitting (still in the BF hearth) slag and metallic components of the heat products. In the scull content different slag components present: silicate (38.3–47.2% SiO2) with high content of К2О + Na2O (до 32.2%), MnO (up to 7.5%) and FeO (up to 33.2%). During the quick cooling of the components on the hearth cooler, different compositions are formed: X-ray amorphous “glassy phase”, olivine composition slags of Ca(Mn,Fe,Mg)SiO4 type, wollastonite, melilite with high amount of iron and manganese. Fine inclusions of titanium nitride are presented in the scull in a small amount, as well as manganese and silicon nitrides and carbonitrides, perofskite CaTiO, the role of which is insignificant in the scull forming.

Abstract:
Abstract Because of its low cost, steel scrap is one of the most important raw materials for the production of ductile iron (DI). The amount of carbide-promoting elements in steel scrap, such as chromium, manganese, molybdenum, niobium and vanadium, is expected to increase in the future. Most of these elements have a negative impact on the microstructure and mechanical properties of DI. The solubility of carbide-promoting elements in solid solution-strengthened DI materials, standardized in DIN EN 1563:2011, is modified by the high silicon content. For these new materials, the tolerance limits for carbide-promoting elements and their mutual influence must be known to ensure a sustainable production process. To investigate the individual and combined impact of carbide-promoting elements on the carbide content in high-silicon ductile iron EN-GJS-500-14, experimental investigations and thermodynamic–kinetic microstructure simulations were carried out. Microstructure was characterized using metallographic analysis, and quantitative relations between chemical composition and microstructure were developed by means of regression analysis. Besides this quantitative analysis, it was found that the formation of grain boundary carbides can be detected via thermal analysis. Furthermore, experiments and simulations showed that vanadium promotes the formation of chunky graphite in high-silicon DI castings.

Abstract:
Abstract The work determined the influence of aluminium in the amount from about 0.6% to about 8% on graphitization of cast iron with relatively high silicon content (3.4%-3.9%) and low manganese content (about 0.1%). The cast iron was spheroidized with cerium mixture and graphitized with ferrosilicon. It was found that the degree of graphitization increases with an increase in aluminium content in cast iron up to 2.8%, then decreases. Nodular and vermicular graphite precipitates were found after the applied treatment in cast iron containing aluminium in the amount from about 1.9% to about 8%. The Fe3AlCx carbides, increasing brittleness and deteriorating the machinability of cast iron, were not found in cast iron containing up to about 6.8% Al. These carbides were revealed only in cast iron containing about 8% Al.

Abstract:
Cast irons are basically binary alloys of iron and carbon having carbon exceeding its maximum solid solubility in austenite but less than the carbon content of iron carbide. However, like steels, cast irons have varying quantities of silicon, manganese, phosphorus and sulphur. Silicon plays an important role in controlling the properties of cast irons and for this reason, the term cast iron is usually applied to a series of iron, carbon and silicon alloys. Special purpose cast irons include white and alloy cast irons which are mainly used for applications demanding enhanced abrasion, corrosion or heat resistance. In present study, corrosion resistant cast irons are of our interest.

Abstract:
The future development of Ural mineral and raw materials base of steel industry is considerably stipulated by the development of deposits of titanium-magnetite ores, the reserves of which are accounted for near 77% of iron ores of Urals. It was shown, that the content of titanium dioxide as well as harmful impurities in the titanium-magnetite have the decisive meaning for selection of processing technology of them for extraction out of them vanadium and other useful components. Technological schemes of the titanium-magnetite enrichment and industrial methods of titanium-magnetite concentrates processing considered. Examples of titanium-magnetite processing by coke-BF and coke-less schemes given. The problems of blast furnace melting of titanium-magnetite ores highlighted. Main problems relate to formation of refractory compounds in a form of carbo-nitrides during reduction of titanium and infusible masses in blast furnace hearth. It was shown, that intensification if carbides precipitation is stipulated by increase of intensity of titanium reduction at increased temperatures of a heat products and requires the BF heat to be run at minimal acceptable temperature mode. Technological solutions, necessary to implement in blast furnace for iron ore raw materials with increased content of titanium processing were presented, including increase of basicity of slag from 1.2 to 1.25-1.30, increase of pressure at the blast furnace top from 1.8 to 2.2 atm, decrease of silicon content in hot metal from 0.1 to 0.05%, application of manganese-containing additives. It was noted, that theoretically the blast furnace melting of titanium-magnetite is possible at titanium dioxide content in slag up to 40% when application of the abovementioned technological solutions, silicon content in hot metal to 0.01% and very stable heat conditions of a blast furnace. The actuality of titanium and its pigmental dioxide production increase was noted. Possibilities of development of Medvedevskoje and Kopanskoje deposits of high-titaniferous ores in Chelyabinsk region with extraction not only iron and vanadium but also titanium considered.

Abstract:
Results of study of lining and scull of the hearth of blast furnace No. 2 of JSC EVEAZ ZSMK presented, done after BF stop for major overhaul. It was determined, that the scull has a zonal structure, due to different conditions of the forming of it during the furnace running and blowing-down. The scull consists of isolations of graphite, metal and slag inclusions having distinctly lamellar structure. Number of slag inclusions in the scull of the hearth walls lower the hot metal tap hole is not big and sharply arises in samples at levels above the tap hole. In metal structure within the scull ferrite (a-Fe) prevails, also there are some lamellar graphite isolations and perlite. Quantity and thickness of metal isolations in the samples increases from the scull periphery to the center of blast furnace (from 20–30% and tens of microns to 70–90% (mass) and 30–50 microns correspondently) and decreases from the lower part of the hearth wall to the upper one. Titanium nitride (osbornite) TiN and titanium oxide (rutile) TiO2, sulfides of calcium, iron, manganese, silicon carbide SiC present in the scull in a small quantity (less 2%). In samples taken higher the hot metal tap hole, in the scull slag isolations there are a considerable amount of alkali metals oxides and sulfides, and phosphide and iron sulfides were exhibited in the metal phase. It speaks about considerable evaporation/sublimation of compositions of potassium, sodium, Sulphur and phosphorus in the blast furnace hearth following by their condensation/crystallization at the cooled lining of hearth walls.

Abstract:
The article describes the technology of hardening the working bodies of agricultural machines based on the use of the electric spark energy and vibration arc discharges or the energy of vibroplasma. (Research purpose). The research purpose is studying of the influence of vibroplasma treatment on the physical and mechanical properties of 65G steel, which is the main material of many working bodies of agricultural machinery. (Materials and methods). The studies were carried out on samples from a coulter disk of 30x30 mm with a thickness of 2 mm. The processing was carried out at VDGU-2 technological installations of electric spark alloying in accordance with the patent of the Russian Federation No. 2655420 and vibration arc hardening. Tungsten-cobalt and copper-graphite rods with diameters of 4 and 8 mm were used as electrodes. (Results and discussion). In contrast to the initial sample, the spectrum of the relatively large area of the 65G steel sample hardened by electrospark treatment showed that cobalt (4.92 percents) and tungsten (16.83 percents) are present in the treated layer in appreciable amounts. Measurements of the elemental composition of the local processing zone showed that the main components of this region are tungsten (64.20 percents) and cobalt (7.55 percent). Carbon, nitrogen, oxygen, iron, manganese, calcium, silicon, aluminum, and a number of other elements are present in the surface layer of the sample with a vibratory arc treatment, but at lower concentrations in comparison with the listed elements for the sample with electric spark treatment. It has been found that the main phases are carbide and iron oxide, as well as metallic iron. After treatment with vibroplasma, there is a so-called zone of thermal influence near the treated zone. (Conclusions). The surface layer formed by processing parts by vibroplasma represents a new composite structure consisting of three layers. The hardening of the base material in the depth of the part during electrospark machining occurs at 0.5-1.0 millimeter, with vibroplasma machining it is up to 3-4 millimeter. The microhardness of the surface layer of products increased by more than three times.

Abstract:
The aim of the project was to establish rate and mechanisms of solid state reduction of manganese ores. The project studied carbothermal reduction of manganese oxide MnO, two Groote Eylandt (Australian) and Wessels (South African) manganese ores in hydrogen, helium and argon atmospheres at temperatures up to 1400C for MnO and 1200C for manganese ores. Experiments were conducted in the fixed bed reactor with on-line off-gas analysis. The major findings are as follows. ?? Rate and degree of reduction of MnO and ores increased with increasing temperature. ?? Reduction of MnO and manganese ores at temperatures up to 1200C was faster in helium than in argon, and much faster in hydrogen than in helium. The difference in MnO reduction in hydrogen and helium decreased with increasing temperature to 1400C. ?? Addition of up to 7 vol% of carbon monoxide to hydrogen had no effect on MnO reduction at 1200C. ?? In the process of carbothermal reduction of ores in hydrogen at 1200C, silica was reduced. ?? Reduction of both GE ores was slower than of Wessels ore. This was attributed to high content of iron oxide in the Wessels ore. ?? Carbon content in the graphite-ore mixture had a strong effect on phases formed in the process of reduction; thus, in the reduction of Wessels ore with 12-16 wt% C, a-Mn and Mn23C6 were formed; when carbon content was above 20 wt%, oxides were reduced to carbide (Mn,Fe)7C3. ?? Kinetic analysis showed that mass transfer of intermediate CO2 from oxide to graphite in carbothermal reduction in inert atmosphere was a contributing factor in the rate control. ?? High rate of reduction of manganese oxide in hydrogen was attributed to formation of methane which facilitated mass transfer of carbon from graphite to oxide. Hydrogen was also directly involved in reduction of manganese ore reducing iron oxides to metallic iron and higher manganese oxides to MnO. Reduction of Wessels and Groote Eyland Premium Fines ores in the solid state is feasible at temperatures up to 1200C; while temperature for solid state reduction of Groote Eyland Premium Sands is limited by 1100C.

Main purpose of this study was to find the optimum conditions to produce a charge material for ferromanganese production or steelmaking with high content of iron and manganese carbides from Denizli-Tavas manganese ore by carbothermic reduction and investigate the effects of temperature, time, amount of active carbon addition and CaO addition on this reduction. The ore was calcined and then mixed with active carbon and CaO. Experiments were performed in a horizontal tube furnace that can be heated up to 1700 º
C with MoSi2 heating elements. After each experiment weight loss data were obtained and converted to percentage reduction. X-Ray, SEM-EDS and chemical analyses were done in order to determine whether or not carbide phases have been obtained, and calculate the composition of the product. Considering the experimental results, the optimum conditions found for reduction of Denizli-Tavas manganese ore were 1250 °
C, 4 hours, 100% of stoichiometric amount of active carbon and 5% CaO addition. Under the optimum conditions 83.85% reduction of calcined ore was obtained.

Abstract:
A new technique based on the study of the transmitted neutron beam has been developed to study the low-temperature decomposition of austenite in a 0.4 wt.% C–3 wt.% Mn–2 wt.% Si steel. Experiments were conducted in which the neutron beam continuously passed through a specially designed layered sample, the temperature of which could be controlled to allow for a high-temperature austenization treatment followed by accelerated cooling to an isothermal transformation temperature in the range of 275–450 °C. It was possible to measure the volume fraction of the face-centred cubic (fcc) and body-centred cubic (bcc) phases and the carbon concentration of the fcc phase by characterizing the neutron Bragg edges in the transmitted beam. This provides a technique for in situ continuous measurements on the decomposition of austentite. The technique has been validated by comparing the data with other experimental techniques such as dilatometry, quantitative optical metallography and room temperature X-ray diffraction.

Abstract:
The rechargeable lithium ion batteries (LIB) are playing increasingly important roles in powering portal commercial electronic devices. They are also the potential power sources of electric mobile vehicles. The first kind of the cathode materials, LiXCoO2, was commercialized by Sony Company in 1980s, and it is still widely used today in LIB. However, the high cost of cobalt source, its environmental unfriendliness and the safety issue of LiXCoO2 have hindered its widespread usage today. Searching for alternative cathode materials with low cost of the precursors, being environmentally benign and more stable in usage has become a hot topic in LIB research and development. In the first part of this study, lithium nickel manganese cobalt oxide (LiNi0.6Mn0.35Co0.05O2) is studied as the electrode. The materials are synthesized at high temperatures by solid state reaction method. The effect of synthesis temperature on the electrochemical performance is investigated, where characterizations by, for example, X-ray diffraction (XRD) and scanning electron microscopy (SEM), for particle size distribution, specific surface area, and charge-discharge property, are done over samples prepared at different conditions for comparison. The electrochemical tests of the rechargeable Li ion batteries using LiNi0.6Mn0.35Co0.05 cathode prepared at optimum conditions are carried out in various voltage ranges, at different discharge rates and at high temperature. In another set of experiments, the material is adopted as anode with lithium foil as the cathode, and its capacitance is tested. In the second part of this study, the iron based cathode material is investigated. Lithium iron orthosilicate with carbon coating is synthesized at 700℃ by solid state reaction, which is assisted by high energy ball milling. Characterizations are done for discharge capacities of the samples with different carbon weight ratio coatings.

Abstract:
Plus de 4000 exoplanètes ont été découvertes, orbitant autour d’étoiles ayant différentes compositions. Ces exoplanètes sont détectées et étudiées par observations indirectes qui, dans de nombreux cas, donnent accès aux propriétés principales des planètes: leurs masses et leurs rayons. Ces paramètres peuvent être calculés à partir d’un modèle et comparés à ceux observés. Toutefois, cela est plus difficile pour des planètes qui orbitent autour d’étoiles ayant une composition chimique différente du Soleil, par exemple enrichie en carbone, car les propriétés physiques des carbures (i.e. carbures de silicium ou de fer) sont inconnues. Dans cette étude les systèmes Si-C et Fe-Si-C ont été étudiés entre 20 et 200 GPa et 300-3000 K, en utilisant la diffraction de rayons x et l’analyse chimique des échantillons récupérés pour déterminer les propriétés physiques dans des conditions extrêmes. Dans le système Si-C les équations d’états et les modèles thermiques pour les deux phases de basse et haute pression ont été déterminés. Les résultats ont ensuite été utilisé pour calculer la relation masse-rayon de planètes synthétiques ayant un noyau de fer et un manteau de SiC. Concernant le système Fe-Si-C le diagramme de phase ternaire a été reconstruit. En faisant l’hypothèse d’une composition Fe-Si-C pour un noyau planétaire, quatre différentes séquences de cristallisation ont été démontrées, déterminant des comportements dynamiques très diffèrent. En conclusion la relation masse-rayon n’est pas suffisante pour déterminer la composition et la structure interne des exoplanètes observées mais des données relatives à la chimie du système planétaire sont requises
More than 4000 exoplanets have been discovered, orbiting around stars with a wide variety of composition. Such planets are detected and studied through indirect methods that in many cases give access to the main properties of the planets: mass and radius. The same parameters can be calculated from a chosen model and compared to the observed ones. However it is difficult for planets orbiting around stars with compositions very different from our Sun, for example carbon enriched, as the physical properties carbides (i.e. silicon carbides and iron carbides) at extreme pressure are unknown. In this work the Si-C and Fe-Si-C systems were studied in the range between 20 and 200 GPa and 300-3000 K employing X-ray diffraction and chemical analyses on the recovered samples were used to determine the physical properties at extreme conditions. In the Si-C system the equations of state and thermal model for both the low pressure and high pressure phases were determined. The results were then used to model a mass radius plot for different archetypal planets with a Fe core and SiC mantle. Regarding the Fe-Si-C system a ternary phase diagram was reconstructed up to 200 GPa and 3000 K. Assuming Fe-Si-C as main component of planetary cores, four different crystallization paths are individuated, giving rise to way different dynamical behaviour. We conclude that using only mass radius relations is not sufficient to determine the interior composition and structure of an observed exoplanet and further data relative to the chemistry are needed, for example the composition of the host star

Abstract:
Eighteen elements, including: carbon, oxygen, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, potassium, calcium, titanium, chromium, manganese, iron, nickel, strontium, and barium were measured using a scanning electron microscope with energy dispersive spectroscopy from deposits. The deposits were collected by burning eight different coals in a 160 kWth, staged, down-fired, swirl-stabilized combustor. Both up-stream and down-stream deposits from an oxidizing region (equivalence ratio 0.86) and reducing region (equivalence ratio 1.15) were collected. Within the deposits, the particle size and morphology were studied. The average particle cross-sectional area from the up-stream deposits ranged from 10 - 75 µm2 and had a standard deviation of 36 - 340 µm2. These up-stream particles were of various shapes: spherical, previously molten particles; irregular particle that had not melted, hollowed spherical shells; and layered or strands of particles. These particles were a mixture of burned and unburned coal being deposited at various stages of burnout and having completed some burnout after deposition. The average particle cross-sectional area from the down-stream deposits ranged 0.9 - 7 µm2 and the standard deviation range of 2.6 - 30 µm2. The shape of the particles on the bottom sleeves are typically spherical indicating melting prior to deposition. Particles contained a distribution of elemental compositions that were not tightly grouped on ternary phase diagrams. This indicated that particles were not single compounds or phases but each particle contained a mixture of multiple compounds. Coals' deposit sulfur was strongly correlated with the calcium and iron content of the ASTM ash analysis. The low rank sub-bituminous and lignite coals that had high calcium content produced high sulfur deposits, particularly in the oxidizing region, down-stream deposits. The high iron bituminous coals, also produced high sulfur deposits, but more so in the reducing region, up-stream deposits. The low calcium and low iron coals produced low sulfur deposits. Mahoning was an exception being high in iron content but remaining low in sulfur content in the deposit. Gatling coal showed numerous deposit particles that contained only iron and sulfur consistent with the high pyrite content of Gatling coal. The average concentration of chlorine was insignificant in all of the deposits with the concentration being less than 100 ppm. Individual particles containing chlorine were found and were associated with potassium, sodium, and iron.

Abstract:
The phase composition and microstructure of ternary alloys, Al–Ca–X (where X = (Silicon) Si, (Magnesium) Mg, (Zinc) Zn, (Copper) Cu, (Nickel) Ni, (Iron) Fe, (Manganese) Mn, and (Scandium) Sc), developed based on Ca-containing eutectics have been studied. In most systems, ternary compounds are detected. It is found that the structure of Ca-containing eutectics is much finer than that of Al–Si alloys. Such alloys have a good combination of technological properties during casting and deforming. Because of the high volume fraction of Ca-containing particles (up to 33 vol.%), they may be considered as promising “natural composites.” The strength properties of Al–Ca–X alloys may be significantly enhanced by adding Sc and Zr, forming L12 nanoparticles. Alloys of the system Al–Zn–Mg–Ca can reach hardnesses higher than 200 HB, which gives reason to expect good strength properties. With the example of the Al–9%Zn–3.5%Mg–3%Ca model experimental alloy based on the (Al) + (Al,Zn)4Ca eutectic, the possibility, in principle, of manufacturing rolled sheets has been demonstrated.

Abstract:
Of the naturally occurring nonradioactive elements, hafnium was the next to last to be discovered, preceding the discovery of rhenium by 3 years. It can boast of holding a very strange record: the number of claims for its discovery over the years is unequaled by any other element. This record was the cause of frustration for many scientists who, over the years, took turns in attempts to isolate it. The reason that hafnium remained undiscovered until 1922 lay not so much in that its presence in nature (long known to be quite scarce) wasn’t looked for, but in its peculiar chemical properties that bound it up intimately with zirconium. Toward the end of the 18th century, Martin Heinrich Klaproth melted some forms of yellow-green and red zirconium with sodium hydroxide and then digested the residue several times with hydrochloric and sulfuric acids to eliminate the extraneous silicon. The solution, thought to contain a number of elements, produced, upon addition of potassium carbonate, a generous precipitate. The oxide that Klaproth collected did not seem to belong to any known substance, and he called it terra zirconia. With the passing of the years, he and many other chemists, among them the renowned Jons Jacob Berzelius, determined the elemental composition of zircon and of its correlative minerals. Far from being simply ZrSiO4, zircon contained traces of iron, aluminum, nickel, cobalt, lead, bismuth, manganese, lithium, sodium, zinc, calcium, magnesium, and uranium and small amounts of the rare earths. Some impurities persistently resisted separation from zirconium oxide or zirconia and were taken erroneously for oxides of new elements (new earths). In 1825, Johann Friedrich August Breithaupt (1791–1873) reported the presence of a new element, ostranium, isolated from ostranite, a mineral similar to zircon. Twenty years later, the Swedish chemist, mineralogist, and metallurgist Lars Fredrik Svanberg (1805–78) announced the discovery of a new element. In his publication of 1845, he asserted that the zirconium oxide obtained from a variety of Siberian, Norwegian, and Indian zircon samples was in reality composed of two earths: one, zirconia, already noted, and another unknown earth.

Abstract:
Abstract The well-known industrial standard called A36 alloy steel is an iron-based alloy that has many applications due to its ability to be easily machined and welded. The alloy has less than 0.3% carbon by weight and is therefore considered a low carbon alloy. Because of this low carbon content, the alloy is useful as a general-purpose steel. It is altogether strong, tough, ductile, weldable, and formable. It is used in the construction of bridges, buildings, automobiles, and heavy equipment as well as in the construction industry. A36 steel also contains small amounts of other elements including manganese, sulfur, phosphorus, and silicon. These elements are added to give the steel alloy desired mechanical and chemical properties. The A36 steel alloy gets the number 36 in its name because of its yield strength. The steel, in most to all configurations, will have a yield strength of a minimum of 36,000 pounds per square inch. This shows high ductility in the material. The physical characteristics and molecular structure of A36 steel are also well known. However, there is little known about the effect of high-velocity impact on the crystalline structure and material phase of this metal alloy. Sections of approximately 90 × 90 square microns were cut off the test samples, keeping with the required standards for surface finish. These surfaces were examined and analyzed after impact. The surface sections were selected from a range of areas including those immediately under the impact crater to locations not physically affected by the impact. Three different impact speeds were applied, and the prepared samples were examined. An EBSD (Electron Backscatter Diffraction) imaging microscope is used to examine the crystalline structure of the test sample post-impact. Most metals crystallize in one of three prevalent structures: body-centered cubic (BCC), hexagonal close-packed (HCP), or face-centered cubic (FCC). Since these crystalline structures are the most expected lattice formations, the samples are examined post impact for changes in the allocation of molecular structure. The results were then tabulated according to the regions relative to the impact crater. In previous research, results show that post-impact inspection of HCP phase change, in iron specifically, is completely and rapidly reversible during impact. However, in this study, traces of HCP were found at some locations in all stages of post-impact. This study also found that the BCC crystalline structure remained the dominant phase structure after impact. This is true with all test samples and all levels of shock loading.
