Abstract: Many industries desire to use aluminum alloys due to their properties, including low weight, good strength properties, corrosion resistance and good castability. This growing popularity of aluminum alloys increases the requirements for their purity and hence any associated structural defects and degradation of casting properties. [..] Read more

Abstract: This paper aims to assess the efficiency of graphite impellers type A and B, investigated in the study of an aluminum refinement process using a physical model of the foundry degassing unit. This model operates in the laboratories of the Environmental Research Department of the Institute of Technology and Business in České Budějovice. [..] Read more

Abstract: Selective laser melting (SLM) is a metal additive manufacturing technology that allows the fabrication of complex near-net-shape titanium parts. Among possible applications, titanium is important for the biomedical sector, in particular for orthopaedics due to its low elastic modulus, biocompatibility, high mechanical strength and corrosion resistance.

Abstract: Titanium shows minimal encapsulation when implanted in bone tissue and develops a direct interfacial contact with bone. The higher surface roughness of titanium leads to a stronger anchorage in comparison with polished smooth surfaces, but the fixation is due to mechanical interlocking rather than chemical bonding.

Abstract: The purpose of this work is to investigate the structure formation in intermetallic alloys by metallothermic reduction of oxide titanium-containing raw materials. The diagram feature of the state of the TiAl system is that a whole spectrum of intermetallic compounds is formed in it: two intermetallic compounds with wide homogeneity regions (α2-Ti3Al, γ-TiAl), two intermetallic compounds with narrow homogeneity regions (TiAl2 and TiAl3) and a number of metastable phases.

Abstract: A study of A3003 aluminium alloy in H12 temper regarding microstructure analysis, tensile testing, fatigue loading and fractography of fracture surfaces was carried out. Specimens were cyclic loaded at five stress amplitude levels of 62, 68, 70, 72 and 76 MPa so that the results for both the low cycle fatigue and high cycle fatigue are obtained. [..] Read more

Abstract: Among additive manufacturing technologies, robocasting emerges as a versatile and an affordable method for processing metallic materials. However, the success and competitiveness of robocasting depend on the development of easy-to-process metallic inks that do not generate residues after debinding and production of high purity metallic parts.

Abstract: Aluminum alloys as hypoeutectic AlSi9Mg alloy have at microstructure a granular and acicular β phase, with α phase as matrix. The hard, irregular, often pointed β phase is responsible for the poor mechanical properties of said alloy. [..] Read more

Abstract: This article is focus on different alloys used to casting same part ,,COVER” 5 different aluminum alloys were studied for the best mechanical properties. Mechanical properties were evaluated in the same place from casting. [..] Read more

Abstract: One of the stages of extracting gold and platinum from copper-nickel sulphide materials is their melting in electric furnaces, where the melt is separated into matte and slag. Gold and platinum are concentrated in the matte, but a significant part of them ends up in the slag, which reduces the recovery of metals. [..] Read more

Abstract: Aluminum alloy EN AW-2024 (AlCu4Mg1 - dural) – Al-Cu-Mg group is one of the most used alloys from this group, which achieves considerable strength after heat treatment. It is an alloy with higher and high strength, but low corrosion resistance. [..] Read more

Abstract: Inoculation of aluminum alloys is performed to improve the mechanical and technological properties of the material. In the case of inoculation, this improvement is mainly due to an increase in chemical and structural homogeneity and a decrease in the tendency to segregate individual elements. [..] Read more

Abstract: The microstructure and fatigue properties of specimens prepared using the selective laser melting technology were analyzed and compared to specimens produced of Ti6Al4V alloy by a conventional way, it means by the casting and forging. The forged samples were studied in both as-received and annealed + hot isostatic pressed conditions; the selective laser melted samples were tested after annealing + hot isostatic pressing.

Abstract: This paper presents the results of phase composition calculating by the CALPHAD method using the Thermo-Calc software package for thermodynamic calculations of high-entropy carbides (TiZrHfTaNb)C, (TiZrHfTaNbW)C, (TiZrHfTaNbMo)C. The starting materials lattice parameters influence the possibility of high-entropy carbides single-phase solid solutions formation. [..] Read more

Abstract: Shape memory alloy represents metallic material that can return to its original forms, shapes, or sizes when subjected to a process of memorization between two transformation phases. The basic application of these materials is always simple, i.e. [..] Read more

Abstract: The aim of the paper is to analyze and describe current usage of project management methodologies in foundries in Europe, Middle East and Africa (EMEA) region that produce castings for automotive, aerospace and oil & gas industry. The research goal is to present which project management methodologies are currently the most used and together with that which project managers certification in the research sample. [..] Read more

Abstract: Maintaining competitiveness is becoming increasingly difficult, not only for industrial companies in an open economy. Especially in times of extended crisis, only those who respond most quickly to change will succeed. [..] Read more

Abstract: The paper presents the results of the analysis of prices of exported and imported steel products in total in Poland. Changes in prices of steel products were analyzed in the period from 2005 to 2020. [..] Read more

Abstract: This paper defines the individual types of depreciation and the methods for depreciation of tangible fixed assets in a metallurgical company. It analyses the potential impact on the economic results and evaluates how the depreciation methods were applied. [..] Read more

Abstract: The aim of the article is to show the use of artificial intelligence in improving the heating process in continuous industrial furnaces. To improve the heating in continuous furnaces, heating control based on models that consider the dimensions, material, and heating method can be used. [..] Read more
