Abstract:
Wear resistance is vital for parts that require sliding contact. Different surface treatments have existed in industry and anodizing is the one of techniques for forming a protective oxide coating to improve hardness and abrasion resistance. [..]

Abstract:
Hot tearing is one of the most critical casting defects that affect the castability of an alloy and the final integrity of a component. Despite being extensively studied over the past 70 years, multiple theories persist regarding the mechanism that control the crack development and the key influencing phenomena. [..]

Abstract:
<div>AlCoCrFeNi2.1 alloy belongs to a group of materials called eutectic high-entropy alloys (EHEAs). These have gained attention due to the fact that there is no so-called "strength ductility trade-off". [..]

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. [..]

Abstract:
<div>This paper concerns the characteristics of the material considered as one of the potentially applicable ones under the research topic "Sustainable lead-free fittings for drinking water and gas installations - machinability and connection possibilities".One of the main assumptions of the project were eliminating the recrystallization annealing process because of the use of controlled cooling after forging. The test material was lead-free brass CuZn21Si3P. [..]

Abstract:
<div>Ti nanoparticles were deposited on a glass substrate by a gas aggregation source and coated with a thin layer of Niunder different deposition conditions. The resulting composite consists either of a mixture of TiO2-covered Ti nanoparticles or core-shell Ti-Ni nanoparticles embedded in the Ni matrix. [..]

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. [..]

Abstract:
<div>The so-called tin pest is a phase transformation of white tin ((Sn)) into grey tin((Sn)), where the disintegration of tin materials occurs due to different thermodynamic stability of the phases with a transition at 13.2 °C. The degradation is relatively slow until -50 °C where the maximum speed is located. [..]

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. [..]

Abstract:
<div>Conventional extraction methods like cyanidation face significant challenges with refractory ores, prompting the need for more sustainable alternatives to gold extraction and its metal production. This study evaluates the application of Ethaline, a deep eutectic solvent (DES) composed of choline chloride and ethylene glycol, for dissolving gold from sulfidic refractory ores under varying pH conditions.
