Unveiling the mechanical and microstructural properties of SiC reinforced aluminum wires recycled from scraps by friction stir extrusion

Friction Stir Extrusion (FSE) has been proven as an effective solid-state process to directly recycle metal chips into high-quality wires/rods/tubes. However, the demand for Al-based composite wires with enhanced properties is substantial, and achieving a uniform distribution of the strengthening phase within the composite wire by establishing a robust metal/ceramic interface remains a significant challenge. In this study, AA6082 Aluminum alloy wires reinforced with 12.5 vol% SiC particles, exhibiting homogeneous particle distribution and superior mechanical properties, were successfully produced through the FSE technique. The investigation focused on examining the influence of processing parameters and the addition of SiC reinforcement on the microstructure and mechanical characteristics of the extruded wires. Scanning electron microscopy (SEM), Electron Backscatter Diffraction (EBSD), together with microhardness, bending, and tensile tests, were used to comprehensively analyze the resulting properties. The findings demonstrate a substantial enhancement in the wires' mechanical properties due to the SiC particles. Both tool rotation and tool force were varied during the experimental campaign. Notably, the reduction in porosity and grain refinement resulted in a 12.78 % increase in tensile strength and an 18.6 % improvement in microhardness compared to Al 6082 alloy extruded wires. Grain orientation analysis revealed a fully recrystallized microstructure with a weak texture. Furthermore, the study evaluated power consumption and surface roughness while assessing the feasibility of deposition, thereby highlighting the potential application of this technique in advanced additive manufacturing processes.

Thermo-hydraulic performance of a parabolic trough solar collector filled with three different waste materials

This study presents the experimental investigation of the performance enhancement of a parabolic trough solar collcector (PTC) utilising air as the working fluid and various metallic waste materials as absorber fillers. The experiments have been carried out according to the ISO 9806:2017 norm under clear sky conditions for several days. The application of wire mesh, metal chips and bearing balls as the absorber filling has led to the increase in the performance of PTC and higher outlet temperatures compared to the smooth pipe as a receiver: 282 % (117.6 °C), 250 % (103.1 °C) and 335 % (128.3 °C) respectively. A decrease in PTC performance due to pressure drop was observed. The maximum drop for wire mesh, metal chips and bearing balls filling was: 9.7 %, 5.7 % and 5.7 % respectively. It has been shown that the use of metallic waste materials can significantly improve the thermal performance of PTC, but the rapidly increasing hydraulic resistance may limit their application for high flow rates.

Superconducting surface trap chips for microwave-driven trapped ions

Microwave-driven trapped ion logic gates offer a promising avenue for advancing beyond laser-based logic operations. In future microwave-based operations, however, the joule heat produced by large microwave currents flowing through narrow microwave electrodes would potentially hinder improvements in gate speed and fidelity. Moreover, scalability, particularly in cryogenic trapped ion systems, is impeded by the excessive joule heat. To address these challenges, we present a novel approach: superconducting surface trap chips that integrate high-Q microwave resonators with large current capacities. Utilizing sub-ampere microwave currents in superconducting Nb resonators, we generate substantial magnetic field gradients with significantly reduced losses compared to conventional metal chips. By harnessing the high Q factors of superconducting resonators, we propose a power-efficient two-qubit gate scheme capable of achieving a sub-milliwatt external microwave input power at a gate Rabi frequency of 1 kHz.

Исследование параметров системы аспирации рельсошлифовального поезда

The rail-grinding technology is used for the railway network of the JSC RZhD to eliminate rail defects and extend the lifecycle of the railway track. In order to implement the rail-grinding technology, currently, rail-grinding trains RShP-48 are used. Rails are ground with special grinding wheels made of zirconium electro-corundum manufactured based on aluminum oxide and zirconium oxide, with bakelite organic bond as a binder. In addition, the abrasive wheel composition includes various chemical components. When an abrasive tool is destructed, grinding waste in the form of suspensions is generated during its mechanic work. The suspensions spread over long distances and negatively affect both the environment and the working conditions of the rail-grinding train maintenance personnel. Today, the company «Sinara — Transport Machines» is developing a new rail-grinding train RShP 2.0 with a pre-installed aspiration system to collect grinding wastes for further utilization. When developing the technical design of RShP 2.0, the main characteristics of the aspiration system have been determined. In order to confirm the efficiency of the obtained parameters of the aspiration system, laboratory tests have been conducted on a special rail-grinding unit. According to the results, the aspiration system with the stated technical characteristics absorbs the fine fraction of grinding products which is about 50 % of the total lost mass of the grinding wheel. Considering a large abrasive that sticks to the spark arrestors together with metal chips, the aspiration system RShP 2.0 will enable removing up to 90 % of grinding waste.

Critical analysis of enhanced photovoltaic thermal systems: a comparative experimental study of PCM, TEG, and nanofluid applications

Phase change materials (PCM), thermoelectric generators (TEG), and nanofluids are popular methods investigated for improving conventional photovoltaic thermal (PVT) systems. These methods are particularly used in warm climates where high temperatures negatively impact photovoltaic (PV) power output and energy efficiency. This experimental study evaluated the effects of 32 °C melting point PCM and TEG integration on PVT units, as well as 42 °C melting point PCM and nanofluid incorporation on concentrated PVT (CPVT) units. Technical, exergetic, and economic performance were compared using a small-scale PVT module. Low-cost commercially available materials were used to construct all PVT units. Industrial metal waste was introduced to enhance the thermal conductivity of paraffin wax and salt hydrate PCMs. The results indicated that applying PCMs, porous media, and concentrator plates increased energy generation, potentially offsetting their higher initial cost and achieving an energy cost of approximately $0.135/kWh. However, TEG and nanofluid implementation remained uneconomical, leading to a 15–35 % increase in energy cost. The water-based CPVT unit, enhanced with paraffin wax and copper fins, demonstrated the best technical performance. This unit achieved electrical, thermal, and exergy efficiencies of approximately 15.5 %, 37.4 %, and 16.7 %, respectively, with more than a 20 % reduction in cell temperature. The study also revealed that severe structural changes caused by corrosion of metallic materials in hydrated PCMs could alter the melting point by more than 30 %. This change negatively impacts heat storage capacity. Conversely, incorporating metal chips in non-hydrated PCMs improved the time to reach the melting point state by 30–60 minutes.

Tensile Strength and Mode I Fracture Toughness of Polymer Concretes Enhanced with Glass Fibers and Metal Chips.

This study experimentally investigates the influence of metal chips and glass fibers on the mode I fracture toughness, energy absorption, and tensile strength of polymer concretes (PCs) manufactured by waste aggregates. A substantial portion of the materials employed in manufacturing and enhancing the tested polymer concrete are sourced from waste material. To achieve this, semi-circular bend (SCB) samples were fabricated, both with and without a central crack, to analyze the strength and fracture behavior of the composite specimens. The specimens incorporated varying weight percentages comprising 50 wt% coarse mineral aggregate, 25 wt% fine mineral aggregate, and 25 wt% epoxy resin. Metal chips and glass fibers were introduced at 2, 4, and 8 wt% of the PC material to enhance its mechanical response. Subsequently, the specimens underwent 3-point bending tests to obtain tensile strength, mode I fracture toughness, and energy absorption up to failure. The findings revealed that adding 4% brass chips along with 4% glass fibers significantly enhanced energy absorption (by a factor of 3.8). However, using 4% glass fibers alone improved it even more (by a factor of 10.5). According to the results, glass fibers have a greater impact than brass chips. Introducing 8% glass fibers enhanced the fracture energy by 92%. However, in unfilled samples, aggregate fracture and separation hindered crack propagation, and filled samples presented added barriers, resulting in multiple-site cracking.

Improved effective thermal conductivity of sand bed in thermal energy storage systems

Thermal energy storage (TES) is becoming increasingly important in the modern energy landscape. As the global energy demand continues to rise and the integration of renewable energy becomes crucial, there is a growing need for sustainable and affordable ways to store energy. TES materials, such as sand, molten salts and heat transfer fluids, are a significant contributing factor to the cost-effective characteristics of TES systems. In recent advancements, sand has been viewed as a high-potential TES material for TES applications, attributed to its thermal resistance, widespread availability, safety, and affordability. However, the low thermal conductivity of sand remains a challenge for some TES applications. This study evaluates different correlations for effective thermal conductivity in a sand-based experimental study where the best correlation was adapted for a numerical simulation of the sand bed. The study further explores the use of discarded metallic chips to enhance the thermal conductivity of the sand. Our experiments assessed two integration techniques using three distinct metallic materials. It was found that the maximum heat rate could be achieved with 20 % (volumetric basis) of aluminium chips mixed in sand (1.7 times that of pure sand).

Occupational Nerve Injuries due to Metallic Foreign Bodies: A Case Series of Eighteen Patients.

Peripheral nerve injuries (PNIs) remain an important health problem. PNIs mostly affect young men as this age group is mostly involved in road traffic accidents and other injuries at workplace. PNI can occur from foreign bodies like metal chips while working in industries using lathe machines. Among PNI's, injuries to the ulnar nerve, the brachial plexus and the median nerve are the most frequent lesions encountered. This presentation is on a series of 18 cases of nerve injuries among industrial workers located from finger level up to the arm excluding the brachial plexus due to metallic foreign bodies entering while operating lathe machines over a period of two years with patients being followed-up over a one year period. Mean age in this series was 31.3 years with age range 16-40 years and all were males. Two patients had more than one nerve involvement and one patient had associated vascular injury. All the patients showed functional improvement. Most common nerve injured was median nerve. Most common site for nerve injury was forearm. Combined lesions most commonly involved the ulnar and median nerves. Social cost of traumatic peripheral nerve injuries is significant since it has a higher incidence in young, previously healthy, and economically active people.

Axisymmetric Pressing Problem of Discrete Metal Materials

The paper presents an analytically closed solution to the problem of axisymmetric pressing of discrete metal materials by the method of jointly solving the differential equations of equilibrium of the metal and the plasticity conditions of the porous body, taking into account all pressing factors without exception: the type and properties of the charge, loading conditions, porosity, temperature, friction, etc. The purpose of this work is to develop the foundations of the engineering theory of pressure processing of discrete materials using the example of solving the problem of axisymmetric pressing of structurally inhomogeneous metal chips in a movable closed matrix. The basis for constructing a physical and mathema-tical model of the process is the idealized case of uniform compaction of a porous body with the subsequent determination of the lateral pressure coefficient corresponding to the actual degree of compaction at various stages of loading. The resulting equation for the relationship between the stress tensor components and the yield stress and relative compaction density represents the cylindrical Mises plasticity condition, which in the limit at zero porosity transforms into the plasticity condition for compact metals. The boundary value problem is solved for tangential stresses, taking into account the magnitude and direction of action of contact friction forces, which in their physical nature do not differ from the friction forces in the depth of the pressed material. The physico-mathematical model makes it possible to calculate the stress fields and density of the body according to the coordinates of the deformation zone, as well as energy-power parameters (pressure, force, work of deformation) provided that three structural and rheological characteristics are determined: the yield strength, relative compression and the degree of deformation compaction. Due to the fact that the problem is solved in relation to bodies of rotation in a general form and in a general formulation, the solution itself should be considered as methodological for any axisymmetric loading scheme.

Tribological and thermal characteristics of copper-free brake friction composites

Abstract The effects of zinc, steel, aluminum, and brass materials that can be used instead of copper in brake friction composites on braking performance were investigated in this study. The specimens containing three different ratios of metallic shavings were produced by the dry mixing method. In terms of comparison, a total of 16 specimens were examined by producing the specimen containing copper at the same rates and the specimen containing no metallic chip. The weight loss, specific wear rate, and friction coefficient of the specimens were determined by the brake test results. The hardness and density tests were carried out. Thermal conductivity tests of the specimens were carried out to determine the thermal characteristic of copper. Among the metallic chips used, aluminum and steel wool were found to be good alternatives to copper.

Environmental Assessment of Metal Chip Recycling – Quantification of Mechanical Processing's Global Warming Potential

Material recycling is an essential lever for improving the sustainability of production processes. One way of reusing metal chips that occur as waste in machining or other subtractive manufacturing processes is to mechanically pretreat and remelt them. In mechanical pretreatment, the chips are separated from the cutting fluid by a centrifuge and then briquetted directly on site. This simplifies the handling and makes the transport and subsequent remelting more efficient than in thermal processing alone. The main objective of this work is to quantitatively assess the environmental impacts of the described recycling process, focusing on the global warming potential. Furthermore, recycling by means of mechanical chip processing is compared with alternatives such as thermal drying and primary material extraction. A parametric life cycle assessment (LCA) model has been developed for this purpose. The model considers equipment, material, throughput and location variations to analyze different use cases. The results of the LCA of an exemplary use case show that environmental benefits result from a higher bulk density during transport and a lower energy input during remelting due to a lower liquid content.

Solutions to minimise waste formation at machine-building enterprises

The world is striving to create a cyclical economy, which implies multiple use of production waste. In this regard, the problem of waste production, generation and recycling requires an effective solution. Unfortunately, the average level of waste recycling in Russia is about 52%. To improve this indicator, it is necessary to introduce the principles of resource saving into production, to use the most efficient technologies of waste recycling, to apply the principles of eco-design in the development of new products, etc. One of the large-scale types of waste generated at machine-building enterprises can be metal chips contaminated with oil products. The article considers the methods of chip recycling used at machine-building enterprises and chooses the method that allows to improve the quality of remelted metal and reduce environmental pollution.

Inkjet Printed Ti3C2 Electrodes for Anode-Free Zinc-Ion Battery

Additive manufacturing techniques are coming to the fore in many technological fields as cheaper and more versatile manufacturing routes alternative to the physical deposition methods. In particular, when miniaturized, thin-film or patterned structures are needed, Inkjet printing (IJP) has been widely demonstrated as suitable techniques to fabricate coated electrodes and microdevices for many applications including energy storage 1. In this regard, Zinc-ion batteries (ZIBs) are a promising alternative to the traditional lithium-ion batteries due to the abundance and low cost of zinc. In ZIBs, a metallic Zn chips is usually employed as the anode and a variety of materials, such as metal oxides or polymers, as the cathode. Zinc-ion batteries have the potential for high energy density and long cycle life, however they suffer of the well-known issue of Zn dendritic growth and poor efficiency of the plating-dissolution process 2. Ti3C2 MXene have been recently demonstrated as a high-performance “zincophilic” substrate for smooth and efficient zinc with high reversibility 3,4.In this work, we investigate inkjet-printed Ti3C2 MXene thin coatings as an ideal substrate for anode-free ZIBs. Stable aqueous Ti3C2 MXene inks were formulated and successfully inkjet printed on different substrates. The zinc metal nucleation phenomena on MXene 2D sheets were investigated by electrochemical potentiodynamic polarization techniques as well as galvanostatic ones, comparing them to a zinc metallic foil. Ex-situ electron scanning microscopy (SEM) analyses were employed to observe the plated Zn morphology after cycling at both low and high current density. Taking advantage of the smooth inkjet-printed Ti3C2 MXene coatings, electrochemical atomic force microscopy (EC-AFM) was used for the first time to perform in-operando investigation of the Zn plating process, allowing to reveal the early stage Zn plating mechanism on the as-printed Bibliography C.

Flexural strength increases of concrete with AISI 4140 steel chip as reinforcement

This work is an experimental and numerical study of the flexural strength increase in concrete with steel chips as reinforcement. The concrete was reinforced with different thicknesses of AISI 4140 steel chips: 1.0, 1.5, 2.0, and 2.5 mm, respectively. The metal chip replaced the sand in different percentages: 0 %, 15 %, 25 %, and 50 %. A two-level factor analysis was carried out to study the effect of metal chip thicknesses and their percentages on the flexural strength, making 13 different samples. Flexural tests were carried out in triplicate, making 39 tests. The 39 samples were weighed and measured. Flexural tests, the weights, and the measurements showed that the modulus of rupture and the density increase with the metal chip thicknesses and with its percentage from 2.20 to 2.55 g/cm3 and from 4.6 to 8.6 MPa, respectively. Numerical studies made by the Finite Element Method using Calculix® showed that the concrete can be simulated as an elastic isotropic material where the Younǵs Modulus can be supposed equal to the Flexural Modulus, except in the cracking zone of the concrete, where its behavior is not linear. Flexural tests and numerical studies showed that the mechanical behavior of concrete does not change significantly at the elastic zone, but after the elastic zone, when beginning the microcracking, the effect of metal chips as reinforcement agents is noticeable. The increase in flexural strength of the concrete due to the metal chips is noticeable after the first micro-cracks appear in the specimen.

Recycling metal cutting chips into a consolidated deposition with friction surfacing

The objective of this research is to evaluate the feasibility of using metal cutting chips as a feedstock in solid-state metal additive manufacturing, with friction surfacing used as a demonstrator. To date, the recycling of metal cutting chips is an energy-intensive process. Compared to recycling processes that melt down metal chips, friction surfacing is a solid-state process, which should reduce the overall embodied energy needed to reuse the chips. While friction surfacing is primarily used for coating surfaces to improve their wear properties, it is also showing promising results as an additive manufacturing process for repair / remanufacturing features on large metal parts. Metal cutting chips of 316L stainless steel, produced by a milling operation, were pressed into hollow 304L stainless steel rods. The chip-filled rods were used as the [consumable] friction surfacing tools to deposit on 304L stainless steel substrates. The properties of the resultant deposits are analyzed and compared with deposits made by solid 304L and 316L tools, including deposition geometry, efficiency, process forces, and bond strength. Results indicate that a fully consolidated deposition can be created from the metal cutting chips using this process. Compared with a solid 304L tool, deposits made with metal chip-filled tools were narrower but thicker in the steady-state region when deposited with the same process parameters.

Ambient temperature impact on the parameters of the electrical circuit of sensing element in cluster eddy current sensor of metal chips in the lubrication systems of gas turbine engines

The detection of the wear particles in the engines lubrication systems is one of the most effective ways to assess the state of the bearing assemblies of machines and mechanisms. The most promising existing systems for online monitoring of wear particles are based on the eddy current methods for monitored parameters conversion. The reason is that such systems have the ability not only to determine the particle size, but also to recognize its magnetic properties, which makes it possible (under certain conditions) to localize the place of the defect development. At the same time, it is known that the ambient temperature changes in the monitored zone are one of the main external factors that have a significant impact on the informative parameters of eddy current converters. This is of particular importance for debris monitoring systems in high-power plants lubrication systems (e.g. gas turbine engine), where the oil temperature can vary widely (-50...+160 C). The temperature impact on the parameters of the electrical circuit of sensing element in the cluster single-coil eddy current sensor of metal chips, which is a part of the debris continuous monitoring system prototype for high-thrust aviation gas turbine engine, is studied in the article. A typical design of the single-coil sensing element is considered. The study results of the temperature effect on the sensing element inductance, as well as on the parameters of the current lead that connects the sensing element to the matching transformer and to the measuring circuit are presented. Methods for reducing the impact of temperature changes in the monitored area on the parameters of the electrical circuit of the sensing element are proposed, too.

Recycling of brass chips by sustainable friction stir extrusion

Due to the high economic and environmental benefits, researchers have considered recycling metal chips, especially for the more valuable alloys of copper, brass, aluminium, etc. Several methods have been used including casting and solid-state techniques for recycling the metal chips, wasted annually in large quantities by machining processes. This work examines the sustainability of the Friction Stir Extrusion (FSE) technique, as one of the most recently developed methods for recycling metal chips, comparing it to six different casting methods. Four sustainability indicators of economic, environmental, social, and mechanical performance are calculated and compared for the FSE and casting methods, using a multi-dimensional sustainability methodology. In terms of environmental, social, and mechanical indicators, the FSE method gained significantly the highest levels and in overall sustainability, it achieved the best score of 0.78, while the worst casting technique for recycling was 0.514. However, economically, the FSE has not yet gained a foothold in the industry and needs more attention from manufacturers, environmentally friendly craftsmen, and recycling firms side. Despite the higher investment required for the FSE process (compared to conventional casting techniques) and its lower economic feasibility, the FSE is expected to become more economically viable in the future by further research and development in its tools.

Producing Metal Powder from Machining Chips Using Ball Milling Process: A Review.

In the pursuit of achieving zero emissions, exploring the concept of recycling metal waste from industries and workshops (i.e., waste-free) is essential. This is because metal recycling not only helps conserve natural resources but also requires less energy as compared to the production of new products from virgin raw materials. The use of metal scrap in rapid tooling (RT) for injection molding is an interesting and viable approach. Recycling methods enable the recovery of valuable metal powders from various sources, such as electronic, industrial, and automobile scrap. Mechanical alloying is a potential opportunity for sustainable powder production as it has the capability to convert various starting materials with different initial sizes into powder particles through the ball milling process. Nevertheless, parameter factors, such as the type of ball milling, ball-to-powder ratio (BPR), rotation speed, grinding period, size and shape of the milling media, and process control agent (PCA), can influence the quality and characteristics of the metal powders produced. Despite potential drawbacks and environmental impacts, this process can still be a valuable method for recycling metals into powders. Further research is required to optimize the process. Furthermore, ball milling has been widely used in various industries, including recycling and metal mold production, to improve product properties in an environmentally friendly way. This review found that ball milling is the best tool for reducing the particle size of recycled metal chips and creating new metal powders to enhance mechanical properties and novelty for mold additive manufacturing (MAM) applications. Therefore, it is necessary to conduct further research on various parameters associated with ball milling to optimize the process of converting recycled copper chips into powder. This research will assist in attaining the highest level of efficiency and effectiveness in particle size reduction and powder quality. Lastly, this review also presents potential avenues for future research by exploring the application of RT in the ball milling technique.

REGULARITIES OF VIBRATION FINISHING AND GRINDING PROCESSING AND DIRECTIONS OF IMPROVEMENT OF ITS INTENSITY AND QUALITY

The data on the labor intensity of manufacturing engineering products and the share of finishing and grinding operations in the total labor costs of their manufacture are presented. The list and the degree of mastering the technological operations of finishing and grinding processing, performed in the conditions of machine-building industries during the last years are given. The grounds are given for highlighting the method of vibration processing as the most promising for ensuring complete mechanization of the process of finishing and cleaning, as well as achieving high technological characteristics of the surface roughness of parts. An assessment was made of the influence of modes, the trajectory of the movement of the reservoir and the grain size of the granules of the abrasive medium on metal removal. It is indicated that the intensity and quality of vibration treatment is estimated quantitatively by the weight removal of metal and qualitatively by the roughness of the processed surface. It is indicated that the determining factor in this case is the speed of the oscillating movement of granules and parts, the difference of which represents the speed of vibration processing, depending on the speed of the oscillating movement of the medium. It is noted that in order to increase the productivity of the process, it is necessary to increase the speed of the medium by increasing the frequency and amplitude of the reservoir oscillations. The layer-by-layer transmission of a force impulse from the bottom of the reservoir to the bulk medium is considered. The physical meaning of increasing productivity by increasing the amplitude of the reservoir oscillations is indicated. The conditions for obtaining metal removal are indicated, which provide increased efforts for the interaction of granules with parts at high micro-cutting speeds. Experimental studies are described to determine the influence of the amplitude and frequency of oscillations on the results of vibration finishing and grinding. Graphic dependences of metal removal were obtained for various ratios of the sample weight to the weight of the medium granule. The dependence of metal removal on the ellipticity coefficient and the amplitude of the reservoir oscillations was obtained in a similar way. It is noted that the vertical component of the amplitude during in-plane oscillations of the reservoir is the determining factor of the complex influence of the parameters of the ellipse coefficient of the trajectory of the reservoir and its amplitude of oscillations. It has been established that when using a coarse-grained abrasive, the penetration of grains into the metal of the part occurs to a greater depth and larger metal chips are removed with a large metal removal. With a small grain size of the abrasive, small chips are removed with a small metal removal and a decrease in the height of micro-roughness.
