Résumé :
Forty years ago there were essentially no academic departments with titles of “Materials Science” or “Materials Engineering.” There were, of course, many materials departments. They were called “Metallurgy,” “Metallurgical Engineering,” “Mining and Metallurgy,” and other permutations and combinations. There were also a small number of “Ceramic” or “Ceramic Engineering” departments. Essentially none included “polymers.” Over the years titles have evolved via a route that frequently followed “Mining and Metallurgy,” to “Metallurgical Engineering,” to “Materials Science and Metallurgical Engineering,” and finally to “Materials Science and Engineering.” The evolution was driven by recognition of the commonality of material structure-property correlations and the concomitant broadening of faculty interests to include other materials. However, the issue is not department titles but whether a single degree option in materials science and engineering best serves the needs of students.Few proponents of materials science and engineering dispute the necessity for understanding the relationships between processing (including synthesis), structure, and properties (including performance) of materials. However, can a single BS degree in materials science and engineering provide the background in these relationships for all materials and satisfy the entire market now served by several different materials degrees?The issue is not whether “Materials Science and Engineering” departments or some other academic grouping of individuals with common interests should or should not exist.

Résumé :
Increasing global cement and steel consumption means that a significant amount of greenhouse gases and metallurgical wastes are discharged every year. Using metallurgical waste as supplementary cementitious materials (SCMs) shows promise as a strategy for reducing greenhouse gas emissions by reducing cement production. This strategy also contributes to the utilization and management of waste resources. Controlled low-strength materials (CLSMs) are a type of backfill material consisting of industrial by-products that do not meet specification requirements. The preparation of CLSMs using metallurgical waste slag as the auxiliary cementing material instead of cement itself is a key feature of the sustainable development of the construction industry. Therefore, this paper reviews the recent research progress on the use of metallurgical waste residues (including blast furnace slag, steel slag, red mud, and copper slag) as SCMs to partially replace cement, as well as the use of alkali-activated metallurgical waste residues as cementitious materials to completely replace cement for the production of CLSMs. The general background information, mechanical features, and properties of pozzolanic metallurgical slag are introduced, and the relationship and mechanism of metallurgical slag on the performance and mechanical properties of CLSMs are analyzed. The analysis and observations in this article offer a new resource for SCM development, describe a basis for using metallurgical waste slag as a cementitious material for CLSM preparation, and offer a strategy for reducing the environmental problems associated with the treatment of metallurgical waste.

Résumé :
The interface bonding method has a great influence on the mechanical properties of aluminum foam sandwich (AFS). This study aims to investigate the effect of different interface bonding methods on the mechanical properties of AFS. In this paper, the metallurgical-bonding interface-formation mechanism of AFS prepared by powder metallurgy was investigated. The shear properties of metallurgical-bonded AFS were determined by the panel peeling test. The flexural properties and energy absorption of metallurgical-bonded and glued AFS were analyzed through the three-point bending test. The results show that the magnesium, silicon, and copper elements of the core layer diffuse to panels and form a metallurgical composite layer. The metallurgical-bonding strength between the panel and core layer is higher than that of the foam core layer. The peak load of metallurgically-bonded AFS is 24% more than that of glued AFS, and energy absorption is 12.2 times higher than that of glued AFS.

Résumé :
The iron and steel industry is one of the largest sources of waste materials, primarily in the form of steelmaking dusts, sludge and slag. Those wastes are a serious threat to the environment. Main precondition for the protection of natural resources in the environment is to recover raw material and energy from waste. The use of waste as raw materials does not involve the storage and creates the possibility of closure of the existing landfill. The article presented utilization of same metallurgical waste containing 4-20 wt. % zinc in non-metallurgical industry. Performed chemical analyzes of pollutants contained in waste tested (dusts, sludge and slag) and in manufactured products (cement bricks, ceramic construction materials, colored glass products and slag for road construction). Aqueous extracts analysis results were compared with the maximum values for the sewage entering into water and soil. The performed research proves that proposed technologies (production of cement clinker, construction bricks, hollow glass, decorated glass) do not pose threat to environment. Harmful impurities are eluted from the products – clinker, constructions bricks and slag after the recovery of zinc recovery. Proposed technologies substitution of primary raw materials recyclable materials can reduce environmental degradation.

Texte intégral
Résumé :
This paper discusses a sustainable way to prepare construction materials from metallurgical slags. Steel slag, copper slag, lead-zinc slag, and electric furnace ferronickel slag are the most common metallurgical slags that could be used as supplementary cementitious materials (SCMs) and aggregates. However, they have some adverse effects that could significantly limit their applications when used in cement-based materials. The setting time is significantly delayed when steel slag is utilized as an SCM. With the addition of 30% steel slag, the initial setting time and final setting time are delayed by approximately 60% and 40%, respectively. Because the specific gravity of metallurgical slags is 10–40% higher than that of natural aggregates, metallurgical slags tend to promote segregation when utilized as aggregates. Furthermore, some metallurgical slags deteriorate the microstructure of hardened pastes, resulting in higher porosity, lower mechanical properties, and decreased durability. In terms of safety, there are issues with the soundness of steel slag, the alkali-silica reaction involving cement and electric furnace ferronickel slag, and the environmental safety concerns, due to the leaching of heavy metals from copper slag and lead-zinc slag.

Résumé :
The article considers the possibilities of using decarbonization technologies in the production of steel products. The world experience of using advanced technologies is generalized and the possibilities of their application in metallurgical production are presented, taking into account the emissions of carbon dioxide responsible for the greenhouse effect and global warming of the Earth. The directions of research projects in the metallurgical industry, the results and the conclusions that follow from them are presented. Possibilities of application of decarbonization technologies in the process of preparation of charge materials, production of cast iron and steel are shown. It is noted that the trend of decarbonization of steel significantly changes traditional metallurgy. At the same time, the possibilities of modern technologies of metal production do not allow to significantly abandon the use of natural gas and carbon (coal and coke) as a reducing agent and energy source in metallurgical production processes. Possibilities of modern and perspective metallurgical processes concerning production of products with the minimum carbon trace are shown. The problems facing the metallurgy of Ukraine to reduce СО2 emissions and the introduction of technologies for decarbonization of metal production are highlighted. It is shown that for the implementation of steel decarbonization processes it is necessary to take into account the following: the need for structural restructuring of the metallurgical industry; the need for radical modernization of the metallurgical industry through the introduction of fundamentally new energy-saving production technologies; limiting inefficient exports of raw materials and semi-finished products; introduction of "green" steel production technologies; strengthening the role of research in the production of metallurgical products with low carbon footprint; strengthening the interaction of science, enterprises and the state in the implementation of global projects for the production of low-carbon metallurgical products.

Résumé :
The modern development of the construction industry needs to find ways to create new competitive materials. Such materials are polymer composites, since the range of their application can be wide, due to the possibility of regulating their technical properties. This work presents a research on the development and production of polymer composites and products from them with the improved mechanical properties by adding finely dispersed techno-genic mineral raw materials as a functional filler. As a dispersed filler of the polyvinyl chloride composition, waste from the production of refined silicon was used, which is dust from the entrainment of furnaces captured by an electrostatic precipitator. To predict the characteristics of the materials obtained, the applicability criteria of techno-genic raw materials in the polyvinyl chloride composition are studied. Studies of the mechanical and operational properties of the obtained composites have confirmed the possibility of using techno-genic raw materials as functional fillers that affect the mechanics, durability, and also significantly reduce the cost of finished products.

Résumé :
The main objective of this paper is to present results of the research in the development of a specialized self-propagating high-temperature synthesis (SHS) technology for ferroalloy composites, as applied to steelmaking. The problem of creating such a production cycle has been solved by developing a new approach to the practical implementation of self-propagating high-temperature synthesis, as applied to metallurgy. The metallurgical variation of SHS is based on the use of different metallurgic alloys (including waste in the form of dust from ferroalloy production) as basic raw materials in the new process. Here, the process of synthesis by combustion is realized through exothermic exchange reactions. The process produces a composite, based on inorganic compositions with a bond of iron and/or alloy based on iron. It has been shown that in terms of the aggregate state of initial reagents, metallurgical SHS processes are either gasless or gas-absorbing. Combustion regimes significantly differ when realized in practice. To organize the metallurgical SHS process in weakly exothermic systems, different variations of the thermal trimming principle are used. In the present study, self-propagating high-temperature synthesis of ferrovanadium nitride, which is widely used in steel alloying, was investigated. It has been shown that the phase composition of the initial alloy has a profound impact on the regular patterns in ferrovanadium combustion in nitrogen and on the mechanism itself. During the nitriding of σ-(Fe-V), process activation is taking place. The activation is due to the transformation of the intermetallide into an α-solid solution, when the temperature of phase transition is reached (~1200 °C). The composite structure of the products of ferrovanadium is nitriding by the fusion of particles-droplets composed of molten Fe and solid VN.

Focused ion beam (FIB) microscopes, the use of which is well established in the semiconductor industry, are rapidly gaining attention in the field of materials science, both as a tool for producing site specific, parallel sided TEM specimens and as a stand alone specimen preparation and imaging tool.Both FIB secondary ion images (FIB SII) and FIB secondary electron images (FIB SEI) contain novel crystallographic and chemical information. The ability to see “orientation contrast” in FIB SEI and to a lesser extent SII is well known for cubic materials and more recently stress-free FIB sectioning combined with FIB imaging have been shown to reveal evidence of plastic deformation in metallic specimens. Particularly in hexagonal metals, FIB orientation contrast is sometimes reduced or eliminated by the FIB sectioning process. We have successfully employed FIB gas assisted etching during FIB sectioning using XeF2 for zirconium alloys and Cl2 for zinc coatings on steels to retain orientation contrast during subsequent imaging.

The present paper reveals one of the energy efficient ways of science investigation in light construction of materials. The small hollow spheres made from different materials could change the weight of a construction part essentially, used as acoustic and thermal insulation and also as protection against vibrations and energy, induced by plastic deformation of material. They can be used as a unit cell for big parts and alone filled with an inert gas, e.g. fusion targets. The methods of their production could be divided in chemical, powder and metallurgical. The metallurgical method requires the intelligence application, because it is based on the own properties of the materials and boundary conditions of the process, not involving any organically core and preparation of the powder.

Résumé :
Sand has been considered to be something of an immeasurable quantity. There are many indications that this view is no longer valid and that the limiting of natural aggregates usage is doubly justified. Firstly, the extraction of natural aggregates is expensive and has a huge impact on the environment. The main issues in sand and gravel mining are the large areas that are affected, ground water level changes, illegal mining, unsuitability of desert and marine sand, and costs of transport. Secondly, metallurgical waste can be used as a substitute for natural aggregates. This is doubly beneficial—the waste is recycled and the use of natural aggregates is reduced. Waste is stored in landfills that take up large areas and there is also the possibility of ground and groundwater pollution by hazardous compounds. The research presented in this article focuses on the technological conditions of using metallurgical waste in its original form and as a component of recycled concrete aggregate (RCA). The use of metallurgical sludge waste or crushed or round RCA to produce concrete deteriorates the consistency and does not significantly affect the air content and density of the concrete mix. RCA lowers the density of hardened concrete. Metallurgical sludge waste or RCA usage adversely affect the absorbability and permeability of concrete.

Résumé :
Developing cost-effective electroactive materials for advanced energy devices is vital for the sustainable development of electrochemical energy conversion/storage systems. To reduce the fabrication cost of electroactive materials (electrocatalysts and electrodes), growing attention has been paid to low-cost precursors. Recently, mining and metallurgical waste has been used to design electroactive materials, which shows great economic and environmental benefits. Herein, current achievements in the applications of mining and metallurgical waste-derived electroactive materials in sustainable energy conversion/storage fields (batteries, supercapacitors, fuel cells, and small-molecule electro-conversion) are comprehensively analyzed. The waste-to-materials conversion methods and materials’ structure–performance relationships are emphasized. In addition, perspectives related to the further development and applications of waste-derived high-performance electroactive materials are pointed out.

Résumé :
The processing of polymetallic materials provides some challenges to every flowsheet. Within Aurubis Cu-Pb-metallurgical flowsheet, a broad range of raw materials and intermediates are processed. Continuous improvements are required to adapt the flowsheet according to the changing material quantity and quality. Therefore, thermodynamic modeling is the desired and most efficient way to conduct scenario analysis. Hence, databases and software are becoming better and better as the acceptance of this method increased. Further understanding is promoted by conducting experimental test work to validate the calculated results. In this research work, the impact of various oxygen potential on the formation of the condensed phases’ slag, matte, speiss and crude lead were investigated. A frequent check of slag metallurgy, in particular, the iron and lead concentration, provide feedback if the metallurgical process is operating at the right oxygen potential. Following, the calculated distribution coefficients for Cu, Pb, As, Sb, Sn and Ni between matte/speiss and speiss/lead are discussed.

Résumé :
From the point of view that pellet microstructure determines its metallurgical properties, an improved support vector machine (SVM) model for pellet metallurgical properties forecast is studied based on the mineral phase characteristics, in order to improve the evaluation efficiency of pellet metallurgical properties. The forecast model is composed of a SVM with self-adaptive selection of kernel parameters and a SVM with self-adaptive compounding of kernel types. This not only guarantees the super interpolation ability of the forecast model, but also takes into account its good generalization performance. Based on 200 sets of original sample information, the quantitative relationship between the main characteristics of mineral phase and the grade labels of pellet metallurgical properties (reduction expansion index RSI, reduction index RI, low temperature reduction and pulverization index RDI) was determined by the improved SVM model. With the simulation results of RSI, RI, and RDI with the accuracy of 100%, 98%, and 100% respectively, the precise forecast of pellet metallurgical properties based on mineral phase is realized.

Texte intégral
Résumé :
Simulating the additive manufacturing process of Ti-6Al-4V is very complex due to the microstructural changes and allotropic transformation occurring during its thermomechanical processing. The α -phase with a hexagonal close pack structure is present in three different forms—Widmanstatten, grain boundary and Martensite. A metallurgical model that computes the formation and dissolution of each of these phases was used here. Furthermore, a physically based flow-stress model coupled with the metallurgical model was applied in the simulation of an additive manufacturing case using the directed energy-deposition method. The result from the metallurgical model explicitly affects the mechanical properties in the flow-stress model. Validation of the thermal and mechanical model was performed by comparing the simulation results with measurements available in the literature, which showed good agreement.
