One possibility for energy storage are fuels. With gaseous fuels like hydrogen or methane, significant efforts are necessary for a feasible storage in terms of compression or liquefaction. This is of particular importance in the mobility sector. An alternative to high-pressure or cryogenic gas storage is the storage by adsorption in porous media using nano-carbons, metal–organic...
As a nickel-based super alloy, Inconel 718 (In718) has gained attention in different industries due to its excellent mechanical behavior under elevated temperatures. Nevertheless, its low thermal conductivity limits its application in many fields, such as thermal energy conversion and heat dissipation. GRCop-84, in contrast, is a copper-based alloy with extremely high thermal...
Choice selection and application variation of physical beneficiation techniques usually employed on heavy minerals (HMs) depends greatly on mineralogy, composition, shape, particle size distribution, and physicochemical properties of the minerals. Recent advancements in the applications of HM products by modern science, engineering, technological, and metallurgical production...
Commercial electrical steels, Fe-Si alloys with < 4 wt.% Si, are inexpensive and efficient materials for electrical power conversion. Further efficiency improvements require increasing the silicon concentration to 6 wt.%, at which point the material becomes brittle and difficult to form by conventional rolling and sheet fabrication methods. Additive manufacturing stands to...
Models exploring electrochemistry-mechanics coupling in liquid electrolyte lithium-ion battery anodes have traditionally incorporated stress impact on thermodynamics, bulk diffusive transport, and fracture, while stress-kinetics coupling is more explored in the context of all solid-state batteries. Here, we showcase the existence of strong link between active particle surface...
Flora and fauna have evolved to distribute their structural mass efficiently in response to their environment. Inspired by this structural efficiency, functionally graded lattices (FGL) are an emerging subset of non-uniform lattices that employ density gradients for a function-driven mechanical response. These gradients are controlled by stepwise or continuous changes in the...
The article describes the application of the Kaplan–Meier and Weibull procedures for the qualitative assessment of aluminum bronzes obtained from the remelting of metals (e.g., copper, aluminum, iron, manganese). The analysis was carried out on the example of selected bronzes, evaluating the influence of chemical composition on fatigue strength. Melting kinetics and method of...
Functionally graded materials (FGMs) provide a unique solution to combine distinct properties within a single component to enhance its overall performance. Understanding the microstructure and residual stress distribution is particularly important as the material dissimilarity in FGMs can result in high residual stress that affects the mechanical integrity of structural...
Cerium-doped Ca2Al2SiO7 phosphors were synthesized via the combustion technique and annealed at 1073 K, 1173 K, and 1373 K. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), photoluminescence (PL), and thermoluminescence (TL) studies were performed to explore the variation of structural, morphological, luminescence, and...
The effects of hydrothermal and cold sealing processes on the scratch and wear resistance of the anodic layer have been studied. High-pressure diecast AlSi9Cu3(Fe) alloy plates were anodized in a sulfuric acid electrolyte at 16°C and further sealed in boiled water or in a NiF2 solution at 25°C. To analyze the influence of pre-anodizing machining operations, the plates were...
Recycling of aluminum (Al) alloys is critical to meet the demands of global net zero emission targets. The major challenge in the recycling of Al alloys is the presence of a higher content of iron as an impurity in Al alloy scraps, which deteriorates the mechanical properties of recycled alloys. In the present work, Al-7%Si alloys and Al-7%Si-2Fe alloys were cast at three...
High-entropy alloys (HEAs) have attracted much attention for laser additive manufacturing, due to their superb mechanical properties. However, their industry application is still hindered by the high entry barriers of design for additive manufacturing and the limited performance library of HEAs. In most machine learning methods used to predict the properties of HEAs, their...
Aluminum (Al) is used in packaging due to its density, strength, and preservative qualities. The Norwegian packaging flows in 2020 are shown. The paper outlines a laboratory methodology to evaluate the recycling performance of Al packaging where parameters of collection type and pre-treatment are alternated with measurement of yield and analysis of metal quality. Further, the...
