Abstract: Currently, many attempts have been taken to enhance the coercivity and reduce the heavy rare-earth consumption of Nd–Fe–B sintered magnets simultaneously. Some progresses have been made in efforts to introduce Dy and/or Tb in many forms, namely, oxides, fluorides, hydrides, intermetallic compounds and alloys. [..] Read more

Abstract: A comparative analysis of sound emitted by two identical bells cast of bell bronze at different pouring temperatures was carried out. The influence of pouring temperature on the change of sound, the structure, and the porosity of castings was assessed. [..] Read more

Abstract: The paper deals with the optimization of manufacturing of cast metal foams and possibilities of using of this specific material. It is focused on castings from aluminum alloy with a regular arrangement of internal cells. [..] Read more

Abstract: In connection with the end of life of the first commercially produced thin-film photovoltaic panels, the issue of recycling them is very topical. One of the methods for the production of the first photovoltaic cells was thin film technology, based on the CdTe content. [..] Read more

Abstract: The paper presents results of research on a new type of copper component that enables the production of Cu paste. Two pastes were applied during investigations: 1 – Pv19B commercial paste manufactured by Du Pont, 2 – experimental containing more than 50 % copper. [..] Read more

Abstract: The characteristics of cast aluminum alloys are shown in the paper with particular emphasis put on AlSi7Mg alloy and method of silumin modification. Heat treatments have been described to enhance the mechanical properties of cast aluminum alloy. [..] Read more

Abstract: Biocompatible β-titanium alloy Ti35.3Nb7.3Zr5.7Ta0.7O (wt.%) shows high strength and reduced elastic modulus when compared to commercial alloys for total joint endoprostheses (e.g. Ti6Al4V). [..] Read more

Abstract: The hard magnetic materials play an important role in modern technology, e.g. automotive, electronics and many daily use equipment. [..] Read more

Abstract: Titanium alloys such as Ti-6Al-4V are applied in production of structural parts mainly in aircraft and automotive industry, mostly due to favorable relationships between density and mechanical properties as well as good corrosion and crack resistance. Nowadays the most common process of plastic deformation of this material at the industry is hot forging. [..] Read more

Abstract: The paper presents quality control tests performed to monitor aluminum beverage can making process. The analysis comprises tests performed from the moment when the aluminum stripe is about to be fed into the line, to the moment when cans are packed in a palletizer. [..] Read more

Abstract: The work is devoted to the development of technology for obtaining and studying the physicochemical characteristics of oxide coatings of noble (IrO2, RuO2), rare earth (Ta, Nb, Ce) metals, and TiO2, SnO2 based on a titanium, that has undergone the primary chemistry.Important technological characteristics (adhesion, roughness) which show the principal possibility of using the obtained samples as anode materials for the electrolysis of aqueous solutions for the purpose of purifying wastewater or the production of sodium hypochlorite as a reagent were determined. Studies conducted by the XPS, obtained microphotographs and surface profiles confirm the prospect of using these oxide coatings as electrode materials.The electrochemical characteristics we studied make it possible to determine the field of application of the obtained electrodes more accurately for the reaction of chlorine and oxygen evolution with RuO2 and IrO2..

Abstract: The mechanism of dezincification is a relatively common cause of water networks defects and is involved with the composition and the terms of the water flow. This process is a typical representative of the selective corrosion of brass when a portion of the original material from copper and zinc alloy into a spongioid copper changed. [..] Read more

Abstract: Ion implantation and plasma technologies have been proved to be useful techniques to control structure and surface properties of titanium-based materials. In this work the different properties such as microstructure, phase and element composition, microhardness and their influence on the biocompatibility of Ti-based coatings (pure Ti, nitride, oxide, oxynitride) produced by metal plasma immersion ion implantation and deposition (MePIIID) were investigated. [..] Read more

Abstract: The paper is devoted to the issue of co-financing of socially responsible activities of metallurgical companies operating in the Czech Republic from EU funds. The goal of the article is to formulate recommendations for the conduct of companies in this sector of the national economy in the programming period 2014-2020 based on an analysis of projects supporting socially responsible activities of metallurgical companies in the period 2007-2013 and an analysis of relevant government documents and scientific studies.

Abstract: Process capability indexes can be defined as statistical measures of process capability: the ability of a process to produce output within specification limits. It is important especially in case of ribbed bars where all characteristics should be kept. [..] Read more

Abstract: Variability in the modern world is the only thing that is constant. This is due to the globalization of the economy, introduction of new technologies and materials. [..] Read more

Abstract: The organization and supervision of logistics processes which are related to the implementation and delivery of welded pillars, has been presented in this work. The article contains the characteristics of logistics processes that affect the creation of plans to executions’ schedule. [..] Read more

Abstract: The paper presents the analysis of non-conformances of metal plates produced in one of Polish steelworks. Selected quality tools were used in the analysis. [..] Read more

Abstract: All companies have to face a variety of everyday problems, regardless of the sector or particular focus of the organization. It also applies to enterprises in the metallurgical industry. [..] Read more

Abstract: This article focuses on the flexible variable cost budgeting of metallurgical production and its usage for valuation of actual variable cost. In case that this flexible budget is not available, it is not possible to identify the main influences that affect the total differences between the planned and actual values of variable cost.
