Abstract: Small punch test is an advantageous method for evaluation of mechanical properties of components because much less material is required for sampling and subsequent material testing. This is especially valuable in cases where not enough bulk material is available, and the repair of sampled place is complicated e.g. [..] Read more

Abstract: <div>Household appliances often utilize polymer-metal bonding, typically achieved through adhesive bonding or press-fitting techniques. Corrosion resistance is a major factor in household appliances, as corrosion can compromise the functionality and aesthetics of household appliances. [..] Read more

Abstract: The work concerns the analysis of the effect of deformation under static and dynamic conditions of high-manganese X42 steel with the SFE value of 24 mJ/m2 on energy absorption capacity and microstructure. X42 steel is graded as a steel that strengthens by mechanical twinning (TWIP effect). [..] Read more

Abstract: <div>High-strength low-alloy (HSLA) steels are low-carbon steels, making them an excellent construction material for automotive applications, transportation of media such as oil and gas, or responsible marine structures often operating in the harsh weather conditions of northern seas. These steels gain unique properties from micro-additives of Nb, V or Ti (up to 0.15 wt%) and can, for example, reduce the weight of structures by up to 40 % compared with the classic S235JR steel.

Abstract: <div>High-silicon grain oriented steels require strict requirements for chemical composition. The steelmaking process must therefore be extremely tightly controlled due to the need to achieve elemental compactness within strictly defined ranges. [..] Read more

Abstract: <div>The pack-cementation technique was used to manufacture iron (Fe) silicides on Mirrax steel in this study. In an open atmospheric furnace, pack siliconizing process was performed using silicon (Si), ammonium chloride (NH4Cl), and alumina (Al2O3) at 900-950-1000°C and with variable deposition periods of 2-4-6 h.

Abstract: <div>This study investigates the microstructure and thermal performance of Cu-Nb microcomposite conductors welded using various techniques, including thermite welding, laser welding, electron beam welding, and pressure welding with a strong magnetic field. The goal was to assess how different welding methods impact the microstructure and temperature distribution of the welded joints. [..] Read more

Abstract: <div>Influence of various parameters of final machining on stress corrosion cracking of austenitic stainless steel was investigated. Boiling magnesium chloride solution was used as a medium for exposure of samples to find out the susceptibility for corrosion cracking. [..] Read more

Abstract: <div>The boronizing is a thermochemical process in which the boron atoms are introduced into the steel surfaces. This study evaluates the fracture toughness of boride layers developed by powder boronizing of high-chromium steels Sleipner, K 190, Royalloy, Sverker 21 and Sverker 3. [..] Read more

Abstract: <div>Surface treatment methods are often necessary to achieve the desired functionality of parts produced by conventional technologies. Plasma-electrolyte (ELP) technology is an advanced technology for surface treatment. [..] Read more

Abstract: <div>Aircraft fuselage shells made from aluminium are coated to withstand the external influences from aviation. The corrosion protection consists mainly of an anodic oxide layer as the interface (IF) and a primer as the coating. [..] Read more

Abstract: <div>During hot forming, the formation of oxide layers when heating ferrous materials such as steels can hardly be prevented. On the one hand, the formation of oxides is beneficial, as certain oxide phases can have a lubricating effect. [..] Read more

Abstract: <div>The material in nuclear reactors of the VVER 440 type and their main circulation pipes is exposed to temperatures in the range of 100-300 °C during the operating conditions, but in some nodes can be this range of temperatures exceeded. These temperature conditions are suitable for low-temperature sensitization and the microstructure sensitized in this way may be susceptible to inter-granular corrosion during long-term operation.

Abstract: <div>The nickel diamond coating NiDi is made up of two materials: electroless nickel (Ni-P) and diamond. Because of the electroless chemical method of deposition, nickel diamond coating covers all surfaces of the work piece with essentially perfect uniformity. [..] Read more

Abstract: <div>This paper presents the results of a study on composite coatings with a copper matrix and embedded carbon dispersion phase particles. For comparative purposes, the study also includes copper coatings without embedded dispersion phase particles. [..] Read more

Abstract: Controlling the quality of coatings is a significant objective. The large area parts require the construction of multi-track laser cladding layers, which are influenced by the overlapping conditions. [..] Read more

Abstract: <div>An energy and environmental assessment of the processing of secondary raw materials during hydrometallurgical zinc production using the Waelz process was made. The exergy method of thermodynamic analysis was used as a research method. [..] Read more

Abstract: <div>Metal-matrix composites (MMCs) are usually characterized by soft matrix and hard reinforcement. In contrast, we focused in this work on the production and properties of metastable MMCs formed by pure Ag matrix and pure Cu particulates. [..] Read more

Abstract: <div>The aim of this work is to analyze the phase composition, microstructure, and thermal behavior of Sn-3.0Ag-0.5Cu solders with (0.1, 0.4, 1, 4) wt% Ni addition using experimental techniques (scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, differential scanning calorimetry) and computational thermodynamics (Thermo-Calc). The results show that the microstructure of all samples consisted of β-Sn dendrites in eutectic matrix (β-Sn + Ag3Sn) and elongated particles of Cu6Sn5 intermetallic phase. [..] Read more

Abstract: High-temperature superconducting tapes made from rare-earth element barium copper oxide have significant potential for use in high-field magnet applications, owing to their outstanding superconducting properties.However, they experience high magnetization losses when subjected to transient or alternating magnetic fields. To tackle this issue, it is crucial to reduce the width of tapes, which can be achieved through the striation of superconducting layer. [..] Read more
