Abstract: In this study different amounts (up to 15 wt-%) of pure nickel powders were added to pure aluminium powders. The powders were mechanically mixed using a ball mill for 2 hours. [..] Read more

Abstract: Weight reduction is one of the major issues in many industrial areas. New structural materials which meet the highest standards, good mechanical properties, such as strength and ductility, and thermal stability are required. [..] Read more

Abstract: In-situ Low Cycle Fatigue test (LCF) at temperature 635 °C have been performed in Scanning Electron Microscope (SEM) equipped with Electron Backscatter Diffraction analysis (EBSD) on a small dog-bone-shaped specimen of cast Inconel 713LC superalloy. The aim of the work was to study early stage fatigue damage at high temperature by the observations of the characteristic surface relief evolution and crystallographic characterization changes by EBSD together with post observation of internal dislocation structures on FIB prepared TEM lamella.

Abstract: Aluminium alloys belong to the most widely used alloys in industrial applications. Their mechanical properties at elevated temperatures can be enhanced by addition of small amount of zirconium. [..] Read more

Abstract: The paper is concerned with two methods of fabrication Cu-matrix fibrous composites, their microstructure and properties. The composites were reinforced with particles synthesized from elemental Cu and Ti powders. [..] Read more

Abstract: Low strength of biomedical beta titanium alloys in solution treated condition restricts their application. Commercial Ti-Nb-Zr-Ta biomedical alloy was used for this study. [..] Read more

Abstract: The deformation-aging process developed by us for the alloy (wt.%) 16 Co - 33 Cr - 2 Cu - 0.5 Nb - Fe (balance) includes the (1) quenching from 1100 °C to form the single-phase α-solid solution, (2) aging resulting in the formation of spherical α1-phase precipitates during cooling in a temperature range of 650 - 625 °C at a rate of 40 °C/h; (3) monoaxial plastic deformation with the ε = 79 % reduction of area in order to give the shape anisotropy of α1-phase precipitates and to produce the mechanical texture, and (4) final controlled cooling from 605 °C to 540 °C at a rate of 8 °C /h, in the course of which the more complete compositional separation of strongly magnetic α1-phase and weakly magnetic α2-matrix precipitates is reached. The developed heat treatment allowed us to obtain the following magnetic characteristics of the Kh33K16D2B alloy: %& = 64-64.5 kA/m, Br = 1.02-1.1 T and (BH)max = 41.4 - 42.2 kJ/m3.. [..] Read more

Abstract: The quality of cast components is largely dependent on the structure of the casting. With the achievement of optimal fine grain structure, without any internal or surface defects, it is possible to obtain sufficient mechanical properties of the casting. [..] Read more

Abstract: Mining industry in the CIS countries is intensively developing and constantly exploring new fields of natural resources. The opening, exploring and developing of the new fields is highly capital intensive, and requires considerable capital investments in the early stage of development. [..] Read more

Abstract: The paper presents the identification of the distribution structure in the logistic system of an enterprise, while considering the analysis of distribution channels used in business practice and the analysis of the sphere of strategic assumptions for the distribution system. The area of empirical studies covered one of the Silesian metallurgical companies. [..] Read more

Abstract: The paper deals with modelling processes the output of which is affected by both continuous quantitative variables and qualitative variables. Three examples working with simulated data show how to perform regression involving one or two qualitative variables. [..] Read more

Abstract: The steel sector is important for the European Union industrial base. The paper is focused on the analysis of the steel demand in the European Union (EU) and China, the two main producers and traders in the world. [..] Read more

Abstract: The topic of this paper is the electronic reverse auctions with focus on the companies in metallurgical industry. In the introduction part, theoretical information about auctions are provided, along with current researches in this field. [..] Read more

Abstract: The paper presents example results of numerical and photogrammetric analysis leading to identify the causes of cracking and wrinkling during bathtub W1000 production. The verification of tools for the stamping of bathtub W1000 was performed using finite element method and photogrammetric system ATOS Triple Scan. [..] Read more

Abstract: Significance of water footprint assessment in steel supply chain will be discussed in the paper. Water footprint (WF) is new concept which allows quantification of freshwater appropriation. [..] Read more

Abstract: As the competition gets stiffer, it is imperative for many companies to stay competitive. To do so, companies must fine-tune their products in terms of what these products offer to the customer, i.e. [..] Read more

Abstract: The optimization of technological aggregates is important from several aspects. These aspects include high requirements according to the technology of heating, shorter retention times, a rapid heating, and improving of products quality a friendly handling of technologies and a reducing of an ecological footprint. [..] Read more

Abstract: Standards for the quality management system require the application of statistical methods and techniques for measuring, monitoring and process improvement in business practice. The paper addresses the application of statistical methods in the die forging process in a metal working company. [..] Read more
