Abstract: The aim of the following article is to define measures to reduce costs in the metallurgical enterprises. One possibility is the usage of alternative materials – waste. [..] Read more

Abstract: An important contribution for the enterprise is an analysis of the supply chain and market in the area of outsourcing of logistics activities. The paper presents the determination of suitable ways of its application in the selected enterprise. [..] Read more

Abstract: The main purpose of this case study is to identify processes of knowledge management, information and communication technology (ICT) support, and reverse logistics and relations between them in a studied enterprise. Moreover, this study attempts to describe approaches and methods used for performance evaluation of identified processes. [..] Read more

Abstract: The blast furnace process is a collection of a large number of physicochemical, thermal and mechanical processes. All processes do not run in isolation, but in parallel and in a certain interaction. [..] Read more

Abstract: Research and development of construction materials for fusion reactors is an important international task. CuCrZr material is a promising material for fabrication of coolant tubes inside the divertor and other components. [..] Read more

Abstract: This paper is focused at increasing the efficiency of the supply and demand chain in a company engaged in the assembly and production of individual components for the automotive industry. Each company uses different tools to increase its competitiveness. [..] Read more

Abstract: During the pressing of sheet metal parts, cracks may form around the holes that weren't predicted by numerical simulations. These cracks are caused by the partial depletion of the forming capacity at the edges of the hole due to the preparation technology used, most often shearing. [..] Read more

Abstract: Phase identification of corroded metal objects might be problematic because corrosion products are usually a complex mixture of different phases. Furthermore, some of present phases may be either semi-crystalline or amorphous. [..] Read more

Abstract: It is already known, that porphyrin–bases are offering better protection against steel corrosion than metalloporphyrins due to their ability to form very stable metallic complexes by linking in their inner core the iron contained in different steels. In this respect, 5-(4-carboxy-phenyl)-10,15,20-tris-(4-phenoxy-phenyl)-porphyrin was synthesized by multicomponent Adler-Longo synthesis, using two different aldehydes and pyrrole, characterized to certify the structure and further used for formulating double thin layers in all possible combinations with MnTa2O6.

Abstract: Nanoindentation methods used for evaluation surface layers are static indentation and scratch indentation too. Static indentation methods are used namely for evaluation hardness characteristics and for evaluation elastic deformation and plastic deformation of surface layers too based on measurement indentation curves – dependence depth indentation and normal force during all indentation process during loading and unloading.

Abstract: The paper presents the possibility of using the ImageJ computer program for image analysis as a method of assessing the proportion of sample surfaces occupied by corrosion. The program allows to calculate the size of any graphic selection and calculates the number of pixels contained in it, can also measure distances and angles between points or elements of images. [..] Read more

Abstract: Military filters introduced in the Army of the Czech Republic are most commonly used when working with combat equipment and weapons and in manoeuvring activities in the terrain with the use of explosives or chemical warfare agents. During such activities, a large number of pollutants in the form of nanoparticles are released. [..] Read more

Abstract: The iron and steel metallurgy produces significant quantities of solid, liquid and gaseous wastes. The solid wastes like dusts, sludges and mill scales have been stored in dumping area due to their chemical composition, mainly by high content of zinc, cadmium, lead or organic compounds contamination. [..] Read more

Abstract: Top-gas dedusting at blast furnaces (BF) is usually done with venturi scrubbers. However, in recent years, the total dry dedusting of BF top-gas has become a common technology. [..] Read more

Abstract: Ferritic-martensitic Eurofer-97 and oxide dispersion strengthened (ODS) Eurofer steels are potential candidates for structural applications in advanced nuclear reactors. Influence of scandium, yttrium, and aluminum addition was studied at 600 °C using 10-6 wt.% oxygen concentration. [..] Read more

Abstract: Early steel bars corrosion in reinforced concrete elements are difficult to detect because of the lack of visible changes on the concrete surface. To assess reinforcement corrosion risk level without structure damage some non-destructive diagnostic methods are applied. [..] Read more
