Increasing Demand

The growing interest in the process of hydrostatic extrusion is reflected by numerous publications on experimental results, fundamental researches and theoretical studies (e. g., [1] to [20]). In recent years it was the increasing demand for new materials and semiproducts with special cross-section dimensions and properties that substantiated the necessity of defining the application of hydrostatic extrusion in the field of non-ferrous metallurgy. Thus, it is the aim of the researches carried out with the experimental hydrostatic extrusion press type QEH 12 recently installed by the Swedish company ASEA in the Forschungsinstitut für NE-Metalle Freiberg of the VEB Mansfeld Kombinat “Wilhelm Pieck” to solve problems of materials and deformation engineering and to develop new technologies of producing special semiproducts from non-ferrous metals.

Device “DRECE - Dual Rolls Equal Channel Extrusion” is used for production of metallic materials with very fine grain size (UFG). During the actual forming process the principle of severe plastic deformation is used. Metallic strip with dimensions 57×2×1000 mm is inserted into the device. During the forming process the main cylinder in synergy with the pressure roller extrude the material through the forming tool without any change of cross section of the strip. In this way a significant refinement of grain is achieved by severe plastic deformation. This method is used for various types of metallic materials, non-ferrous metals and their alloys. The DRECE device is also being verified from the viewpoint of achievement of a UFG structure in a blank of circular cross-section (wire) with diameter of ϕ 8 mm × 1000 mm.

The Impact

Since the beginning of the XXI century, the raw material of non-ferrous metallurgy began to acquire new outlines. First, due to the growing demand for resources from the rapidly developing countries of Asia (China, India, South Korea), the volume of world production and international flows of both raw ore and ore dressing – concentrates have increased. Secondly, the concentration of countries that produce raw materials on the one hand and consume them on the other has increased. The article is devoted to comparative statistical analysis of international flows of raw materials of non-ferrous metals. The leading countries in the world exporting non-ferrous metal ores and countries importing them have been identified. The impact of new applications of non-ferrous metals on increasing international trade, such as the expansion of the production of batteries for electromobile and consumer electronics, the development of nuclear energy, etc., is highlighted.

Introduction. The article is devoted to the problems of implementation of the state’s entrepreneurial function for diversifying the economy within the framework of global institutional changes during late Middle Ages and early New Age. Particular emphasis is made on economic aspects of transformation of the of non-ferrous metallurgy from small dispersed craft to a centralized industry. The purpose of the article is to determine the behavior of the Russian state and society under the conditions of exchange and production during late XV – early XVIII. Materials and Methods. The research was based on interdisciplinary approach that allows to perform an all-round analysis of the topical area of the research. Specific problems were solved using a set of complimentary methods of historical analysis (retrospective, comparative historical, cross-checking of historical sources) that allowed to create a basis for research. Approximation of existing data into a prognostic function was done with the help of economic theoretical and methodological abstraction (functional analysis method, modeling, positive and normative analysis). Results. The article analyzes the peculiarities of data collection measures on the subject of ore-bearing deposits of non-ferrous metals in the Pechersk region. Implementation of the entrepreneurial function in terms of mining and copper production management on an industrial scale. The reasons for failures in this sphere and the search for alternative solutions for satisfying the public needs for non-ferrous metals. Discussion and Conclusions. The proposed provisions and conclusions create prerequisites for further study of the state policy aimed at effective control over consumption of public goods and their distribution among the population under influence of external factors. This experience can be useful in nowadays conditions of constant pressure of the leading economies and their use of non-economic measures for upholding corporate interests.

Increasing Demand

Rapid development of automotive industry brings increasing demand for die forgings made from non-ferrous metals. Market economy stimulates drop forges to produce forged pieces of highest quality and dimension precision with the accent on reduction in production costs. Precision die forging without flash belongs to progressive and economical technologies of die forgings production. This paper describes an experiment of precision forging in closed die of magnesium alloy type AZ 31. Given alloy type Mg-Al-Zn is suitable for bulk forming and is characterized by good hot formability. Achieved results may be applied in practice at production of longitudinal shaped forgings e.g. levers and connecting rods. In order to verify a design of closed die forging technology regarding the lever-shaped forged piece, simulation program MSC.SuperForge was used. Numeric simulation was significantly helpful at optimization of semi-product shape and dimensions and confirmed correct plastic flow of material in closed die cavity. The objective of this contribution was to point out current trends in searching for economical measures at production of die forgings from alloys of non-ferrous metals.

High Polymers

High polymers, or plastics, are new materials very much with us today. They have already taken over many of the medium-strength uses, and some of the high-strength uses of metals; their volume of production is already greater than that of all non-ferrous metals put together, and a fifth of that of steel, and it doubles about every 6 years. My village ironmonger has sold more plastic than iron for several years now, but plastics are not limited to the knockabout household uses of buckets and so forth, but the best fishing rod, the best pole-vaulting pole, the best motorboat hull will be found to be made of resin-bonded fibreglass. That takes us into the field of composite materials, which others will speak about, but let me say immediately that in these materials, while the glass contributes much of the strength, and particularly the elastic modulus, it is the plastic which contributes the toughness, or counters the brittleness of the glass. It is the intrinsic toughness of the plastics, at their best, which is their most valuable property, and we must seek a deeper understanding of it so that we may know how, perhaps, to increase it, and, most especially, how to prevent the loss of toughness which may occur in unfavourable circumstances.
