Abstract: Ti15Mo metastable β-Ti alloy was subjected to severe plastic deformation by high pressure torsion. The microstructure and chemical composition of the studied Ti15Mo alloy was investigated by scanning electron microscope. [..] Read more

Abstract: Acoustic emission (AE) has been used to study magnesium alloys for many years. The advantage of AE is getting the data from the entire volume with high time resolution. [..] Read more

Abstract: Presented paper compares fatigue behaviour of alloy AlSi9Cu3 produced by gravity casting and Selective Laser Melting (SLM). SLM is one of the additive manufacturing methods. [..] Read more

Abstract: Magnesium alloy AE42 was prepared by powder metallurgy technique of spark plasma sintering. The effect of sintering parameters, particularly sintering temperature, on the microstructure and mechanical strength was investigated. [..] Read more

Abstract: Phase transformations in several metastable β-titanium alloys were studied during linear heating by in-situ electrical resistance measurement. The initial decrease of electrical resistance is caused by a reverse shuffle transformation of athermal ω phase particles to β matrix. [..] Read more

Abstract: In the European Union (EU) serious discussion about granting market economy status (MES) to China for the purposes of trade defence investigations arose in 2016 and the WTO Panel is currently settling this dispute between China and the EU. As the steel sector is very often the target of anti-dumping investigations, firstly, the paper is focused on the analysis of changes in the development of the Chinese, EU and Czech steel production and trade in the period 2001−2016.

Abstract: The article describes a case study of internal transport solutions for persons of executive managers, dispatchers, maintenance staff, referents in the company spread over large premises of technological facilities, warehouses, administrative buildings, managerial centers, transport routes (metallurgical complex, chemical factory) where passenger cars are needed for staying and communicating. The solution can be to assign them to personal service, which often leads to inefficient use for capacitive and economic reasons. [..] Read more

Abstract: Quality management tools are instruments that enable collecting and processing data on events and processes taking place in the organization, related to various aspects of quality management. The most important group of tools is called Seven Basic Tools of Quality, Magnificent Seven or 7 QC Tools. [..] Read more

Abstract: The paper describes a case study of the Activity-Based Costing application in a selected metallurgical enterprise which operates heat treatment processes of metallic materials. Activity-Based Costing (abbr. [..] Read more

Abstract: The article deals with quality power grids in metallurgical industry. Nowadays the power grids are loaded by non-linear loads which cause distortion of voltage and current track. [..] Read more

Abstract: The thesis deals with the control of setting the position of the welding head on the line welded tubes with spiral weld. The industrial line is located in the premises of large metallurgical company in Silesian region. [..] Read more

Abstract: An expression of economical, technical and technological processes by means of models consists in a selection of such facts which can be expressed with help of mathematical tools to provide us a suitable possibility of simpler descriptions or predictions of changes.A situation can occur that a functional expression is not possible or invokes so complicated mathematical relations that their explicit solving is not possible. Some numerical approximations are then attempted or simulated of the processes elements. [..] Read more

Abstract: Current situation on the Czech labor market complicates management of employee performance from many reasons. First of all, it is the absolute lack of qualified work power, secondly inefficient relations between appraisal and remuneration systems and last but not least too complicated employee appraisal systems.The paper presents outputs of more than five-year authors’ own surveys among metallurgical companies located in the Czech Republic, supplemented by outputs of surveys published by renowned HR professionals and counselling companies. [..] Read more

Abstract: The expedition processes of the metallurgical enterprise are characterized by the high complexity that results from wide product portfolio, considerable size of products or the ever-increasing complexity of individual orders. Expedition centers of metallurgical enterprises are historically adapted to the formerly prevailing rail transport, instead of the currently prevailing road transport, and during the development there was not implemented a continuous improvement system that would allow them to adapt effectively to changing conditions. [..] Read more

Abstract: The fundamental role of data analytics in the era of Industry 4.0 is characterized. The main types of data-driven advanced models, including learning systems, are presented. [..] Read more

Abstract: Management of metal and fossil fuels resources is one of the goals of the electromobility development. The aim of this study was to evaluate cumulative metal demand in battery electric vehicles (BEVs) based on life cycle assessment (LCA). [..] Read more

Abstract: Over the last decade, sustainable development is a key strategy used by global leaders in all industries. The implementation of this strategy is regularly published through sustainability reports. [..] Read more

Abstract: To reduce production cost of steel products, it is necessary to control quality stabilization for preventing nonconformance of material properties. The quality stability is improved by constructing a highly accurate prediction model of material properties and incorporating it into the quality control system. [..] Read more

Abstract: The macroeconomic situation in the steel market has a large impact on the functioning of enterprises producing steel and steel-based products. Currently, global steel production continues to increase in 2017, seeing a rise of about 5.3 % over 2016. [..] Read more

Abstract: The paper deals with attributes control charts, especially with the control charts for fraction nonconforming, and their use in retrospective analysis of a process. Several forms of these charts are applied in a case study. [..] Read more
