Abstract: Among titanium-based alloys, Ti-6Al-4V is the most extensively utilized material for structural applications due to its exceptional strength-to-weight ratio, outstanding corrosion resistance, and excellent biocompatibility. It has been widely processed via laser powder bed fusion (L-PBF), a leading additive manufacturing technique that allows for the fabrication of near-net-shape components, offering substantial cost and material savings.

Abstract: Recycled aluminum in tailor-welded blanks (TWBs) offers sustainable solutions for automotive applications. However, variations in impurity levels, depending on the source of the scrap, negatively impact weldability with conventional fusion-based welding methods, limiting its usage compared to primary aluminum.

Abstract: La-Ni compounds are considered promising candidates for future hydrogen-storage applications. Some of the La-Ni phases have been insufficiently studied so far and some critically important data are missing. [..] Read more

Abstract: The strong magnetic field systems are widely used in modern fundamental and applied research, as well as in the most advanced industrial processes. These systems generate magnetic fields ranging from 5 to 100 Tesla, which can expose conductors due to extremely high Lorentz forces. [..] Read more

Abstract: High entropy alloys (HEAs), unlike conventional alloy systems, have attracted growing attention due to their unique combination of structural and functional properties arising from their multi-principal element design. In recent years, Bio-HEAs, composed of elements with proven biocompatibility, have emerged as promising candidates for biomedical applications. [..] Read more

Abstract: This study investigates the feasibility of processing the Zn0.4Mg0.4Ca alloy using Selective Laser Melting (SLM) for potential application in biodegradable medical implants. As part of the initial phase of a broader research effort, five test samples were successfully printed and subjected to basic material characterization. [..] Read more

Abstract: Quarry dust and concrete recycling dust, generated as solid waste during rock and concrete crushing operations, poses a significant environmental challenge. Rich in SiO₂, these fine-grained materials hold potential as fluxing agents in pyrometallurgical processes, yet their metallurgical applications remain underexplored due to the complexity of such waste streams.

Abstract: Manganese ore fines generated during manganese production are either partially recycled as agglomerates using binders, or stored, leading to pollution, and negative environmental impacts due to landfilling. Fines have for long been considered as environmental unfriendly, loss if not recycled and stage threats in the metallurgical industry if not taken care of. [..] Read more

Abstract: The subject of this thesis is to perform mechanical tests of rigid ballistic protection made of composite materials. The topic builds on already developed composite ballistic materials and complements the study of mechanical properties by assessing the changes in these properties after exposure to ultraviolet (UV) electromagnetic radiation.

Abstract: Plasma electrolytic oxidation (PEO) has emerged as a promising surface modification technique to enhance corrosion resistance of magnesium alloys. This study investigates the influence of different surface pretreatments: polishing, grinding, and shot-peening, on the formation and performance of PEO coatings on pure magnesium and WE43 (Mg-4Y-3RE) alloy.

Abstract: In the current business environment, characterised by globalisation and technological advances, metallurgical companies are facing unprecedented challenges. In order to maintain competitiveness, these companies must demonstrate a capacity to respond to these emerging trends. [..] Read more

Abstract: Wastewater contaminant emissions are currently of global concern because they pose risks to the ecosystem and human health. In the present study, a process of coal fly ash leaching by sulphuric acid was carried out. [..] Read more

Abstract: The smelting units, which are used for melting metal waste, are equipped with lances for blowing gaseous media. In case of refining lances, this is oxygen. [..] Read more

Abstract: Assessing and quantifying the impact of various factors on nitrogen content in metal is vital for optimizing technological and operational strategies to minimize or prevent nitridation in the final steel product. Recognizing how individual factors affect nitrogen levels is crucial for predicting nitrogen quantities during both production and processing stages within a closed production cycle. [..] Read more

Abstract: The presented research is focused on identifying differences in the lengths of transition areas during the continuous casting of steel in a three-strand "T"-type tundish, considering various numbers of active strands. The study compares results from three types of measurements: in the first measurement, casting was simulated with three active strands (full capacity); in the second measurement, the simulation was realised with the middle strand disabled; and in the third measurement, the continuous casting process was simulated with one of the outer strands disabled.

Abstract: In light of the European Union’s energy transition strategy aimed at minimizing dependence on fossil fuels, hydrogen has emerged as a key non-carbonaceous reducing agent, offering significant potential for application in metallurgical processes. This study focuses on the material characterization of selected high-grade manganese ores and evaluates their suitability for hydrogen-based reduction. [..] Read more
