In the field of manufacturing technology, a wide variety of approaches are being used to improve both resource and energy efficiency. Efficiency as well as sustainability can be improved by creating a circular economy or through energy-efficient recycling processes. As part of the interdisciplinary research group "Light—Efficient—Mobile" investigations on the energy-efficient friction-induced recycling process have been carried out at the department of Forming and Machining Technology at Paderborn University. E.g. using the friction-induced recycling process, different formless solid aluminum materials can be direct recycled into semi-finished products in an energy-efficient manner. The results of investigations with regard to the influence of the geometrical shape and filling rate of the aluminum particles to be recycled as well as the rotational speed of the continuously rotating wheel are explained in this paper. In addition to the recycling of aluminum chips, aluminum particles like powders from the field of additive manufacturing are processed. Based on these results, the future potentials of solid-state recycling processes and their contribution to the circular economy are discussed. The main focus here is on future interdisciplinary research projects to achieve circularity in the manufacturing of user-individual semi-finished products as well as the possibility to selectively adjust the product properties with the continuous recycling process. article_number: '59' article_type: original author: - first_name: Thomas full_name: Borgert, Thomas id: '83141' last_name: Borgert - first_name: Dennis full_name: Milaege, Dennis last_name: Milaege - first_name: Swetlana full_name: Schweizer, Swetlana id: '8938' last_name: Schweizer - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Borgert T, Milaege D, Schweizer S, Homberg W, Schaper M, Tröster T.

This, in turn, requires an adaptation of standard joining techniques. In multi-material combinations, the importance of integral cast components, in particular, is increasing and poses additional technical challenges for the industry. One approach to solve these challenges is adaptable joining elements manufactured by a thermomechanical forming process. By applying an incremental and thermomechanical joining process, it is possible to react immediately and adapt the joining process inline to reduce the number of different joining elements. In the investigation described in this publication, cast plates made of the cast aluminium alloy EN AC-AlSi9 serve as joining partners, which are processed by sand casting. The joining process of hypoeutectic AlSi alloys is challenging as their brittle character leads to cracks in the joint during conventional mechanical joining. To solve this, the frictional heat of the novel joining process applied can provide a finer microstructure in the hypoeutectic AlSi9 cast alloy. In detail, its Si is finer-grained, resulting in higher ductility of the joint. This study reveals the thermomechanical joining suitability of a hypoeutectic cast aluminium alloy in combination with adaptively manufactured auxiliary joining elements. article_number: '169' article_type: original author: - first_name: Thomas full_name: Borgert, Thomas id: '83141' last_name: Borgert - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Borgert T, Neuser M, Hoyer K-P, Homberg W, Schaper M.

Hereby, the combination of different materials, metal sheets, or cast components, is mechanically joined, often by forming joining processes. The cast components mostly used are high-strength, age-hardenable aluminium alloys of the Al–Si system. Here, the low ductility of the AlSi alloys constitutes a challenge because their brittle nature causes cracks during the joining process. However, by using suitable solidification conditions, it is possible to achieve a microstructure with improved mechanical and joining properties. For this study, we used the twin-roll casting process (TRC) with water-cooled rollers to manufacture the hypoeutectic AlSi10Mg for the first time. Hereby, high solidification rates are realisable, which introduces a microstructure that is about four times finer than in the sand casting process. In particular, it is shown that a fine microstructure close to the modification with Na or Sr is achieved by the high solidification rate in the TRC process without using these elements. Based on this, the mechanical properties increase, and especially the ductility is enhanced. Subsequent joining investigations validate the positive influence of a high solidification rate since cracks in joints can be avoided. Finally, a microstructure-property-joint suitability correlation is presented. article_number: '132' author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin citation: ama: Neuser M, Schaper M, Grydin O.

Thin foils for combined STEM and SEM experiments were prepared by electrolytic twin-jet polishing. They were in-situ heated in a TEM heating stage and observed at 200 kV in the JEOL JEM 2200FS electron microscope equipped with STEM HAADF and BF detectors and SEM BSE and SE detectors working both in composition and topographic modes. The resulting structures were combined with EDS mapping performed directly in the heating holder. Dissolution and transformation of Cu- and Fe-rich particles occur above 500 °C. EDS maps acquired on the foil cooled down to room temperature show that Cu and Fe are both still present in newly formed particles, most likely indicating the presence of the Al7Cu2Fe phase. author: - first_name: Miroslav full_name: CIESLAR, Miroslav last_name: CIESLAR - first_name: Barbora full_name: KŘIVSKÁ, Barbora last_name: KŘIVSKÁ - first_name: Rostislav full_name: KRÁLÍK, Rostislav last_name: KRÁLÍK - first_name: Lucia full_name: BAJTOŠOVÁ, Lucia last_name: BAJTOŠOVÁ - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin - first_name: Mykhailo full_name: STOLBCHENKO, Mykhailo last_name: STOLBCHENKO - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'CIESLAR M, KŘIVSKÁ B, KRÁLÍK R, et al.

For example, in the automotive sector, cast components are used at the junctions of the body and joined with different types of sheet metal and extruded profiles. To be able to join structures consisting of different materials, alternative joining technologies have emerged in recent years. This includes clinching, which allows assembling of two or more thin sheet metal and casting parts by solely cold forming the material. Clinching the brittle and usually less ductile cast aluminium alloys remains a challenge because the brittle character of the cast aluminium alloys can cause cracks during the forming of the clinched joint. In this study, the influence of the heat treatment time of an aluminium casting alloy AlSi9 on the joinability in the clinching process is investigated. Specific heat treatment of the naturally hard AlSi9 leads to a modification of the eutectic microstructure, which can increase ductility. Based on this, it will be examined if specific clinching die geometries can be used, which achieve an optimized geometrical formation of the clinched joint. The load-bearing capacities of the clinched joints are determined and compared by shear tensile and head tensile tests. Furthermore, the joints are examined microscopically to investigate the influence of the heat treatment on the failure behaviour during the load-bearing tests as well as crack initiation within the joining process. article_number: '146442072210758' author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Max full_name: Böhnke, Max id: '45779' last_name: Böhnke - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 citation: ama: 'Neuser M, Böhnke M, Grydin O, Bobbert M, Schaper M, Meschut G.

In spaceframe technology, both sheet metal and continuous cast are joined to castings at the nodal points of the chassis. Since resistance spot welding is not an option when different materials are joined, research is focusing on mechanical joining methods for multi-material designs. To reduce weight and achieve the required strength, hardenable cast aluminium alloys of the AlSi-system are widely used. Thus, 85–90% of aluminium castings in the automotive industry are comprised of the AlSi-system. Due to the limited weldability, mechanical joining is a suitable process. For this application, various optimisation strategies are required to produce a crack-free joint, as the brittle character of the AlSi alloy poses a challenge. Thus, adapted castings with appropriate ductility are needed. Hence, in this study, the age-hardenable cast aluminium alloy AlSi10Mg is investigated regarding the correlation of the different thicknesses, the microstructural characteristics as well as the resulting mechanical properties. A variation of the thicknesses leads to different solidification rates, which in turn affect the microstructure formation and are decisive for the mechanical properties of the casting as well as the joinability. For the investigation, plates with thicknesses from 2.0 to 4.0 mm, each differing by 0.5 mm, are produced via sand casting. Hence, the overall aim is to evaluate the joinability of AlSi10Mg and derive conclusions concerning the microstructure and mechanical properties. article_type: original author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin - first_name: Y. full_name: Frolov, Y. last_name: Frolov - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Neuser M, Grydin O, Frolov Y, Schaper M.

Preparation of these alloys by twin-roll casting (TRC), which combines rapid metal solidification and subsequent plastic reduction in a single processing step, could improve the properties of the alloys compared to materials prepared by conventional direct-chill casting. A commonly used approach for identifying primary phases is a chemical analysis by energy dispersive spectroscopy (EDS). More accurate results can be achieved by combining the method with diffraction analysis. This process can be considerably simplified in microscopes equipped with automated crystal orientation and phase mapping (ACOM-TEM). Al-Cu-Li-Mg-Zr alloy was prepared by twin-roll casting. A combination of TEM and STEM images with chemical analysis by EDS and ACOM-TEM was used to obtain complex information about phases of boundary primary particles. The efficiency of the individual methods for the phase identification in TRC Al-Li-based alloys is discussed. author: - first_name: Lucia full_name: BAJTOŠOVÁ, Lucia last_name: BAJTOŠOVÁ - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin - first_name: Mykhailo full_name: STOLBCHENKO, Mykhailo last_name: STOLBCHENKO - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Barbora full_name: KŘIVSKÁ, Barbora last_name: KŘIVSKÁ - first_name: Rostislav full_name: KRÁLÍK, Rostislav last_name: KRÁLÍK - first_name: Michaela full_name: ŠLAPÁKOVÁ, Michaela last_name: ŠLAPÁKOVÁ - first_name: Miroslav full_name: CIESLAR, Miroslav last_name: CIESLAR citation: ama: 'BAJTOŠOVÁ L, Grydin O, STOLBCHENKO M, et al.

The most common way to characterize the additively manufactured lattice structures is via the uniaxial compression test. However, although there are many applications for which lattice structures are designed for bending (e.g., sandwich panels cores and some medical implants), limited attention has been paid toward investigating the flexural behavior of metallic AM lattice structures with tunable internal architectures. The purpose of this study was to experimentally investigate the flexural behavior of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio (PR). Four configurations of lattice structure beams with positive, negative, hybrid PR, and a novel hybrid PR with graded density were manufactured via the laser powder bed fusion (LPBF) AM process and tested under four-point bending. The manufacturability, microstructure, micro-hardness, and flexural properties of the lattices were evaluated. During the bending tests, different failure mechanisms were observed, which were highly dependent on the type of lattice geometry. The best response in terms of absorbed energy was obtained for the functionally graded hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the positive PR (PPR) structure. This highlights the great potential for FGHPR lattices to be used in protective devices, load-bearing medical implants, and energy-absorbing applications. article_number: '4072' author: - first_name: Osama full_name: Abdelaal, Osama last_name: Abdelaal - first_name: Florian full_name: Hengsbach, Florian last_name: Hengsbach - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer citation: ama: Abdelaal O, Hengsbach F, Schaper M, Hoyer K-P.

With data obtained by this optical method, the transformation kinetics for every area of interest along the whole measuring length of a flat specimen could be analyzed by the generation of dilatation curves. The benefit of this innovative optical characterization method compared to a dilatometer test is that the experimental effort for the design of a tailored component could be strongly reduced to the investigation of only a few tailored thermo-mechanical processed specimens. Due to the implementation of a strain and/or temperature gradient within the flat specimen, less metallographic samples are prepared for hardness analysis and analysis of the microstructural composition by scanning electron microscopy to investigate the influence of different process parameters. Compared to performed dilatometer tests in this study, the optical method obtained comparable results for the transformation start and end temperatures. For the final design of a part with tailored properties, the optical method is suitable for a time-efficient material characterization.\r\n \ Graphical Abstract" author: - first_name: Alexander full_name: Reitz, Alexander id: '24803' last_name: Reitz orcid: 0000-0001-9047-467X - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'Reitz A, Grydin O, Schaper M.

Iron (Fe)-based degradable materials are biocompatible and exhibit good mechanical properties, but their degradation rate is low. Aside from alloying with Manganese (Mn), the creation of phases with high electrochemical potential such as silver (Ag) phases to cause the anodic dissolution of FeMn is promising. However, to enable residue-free dissolution, the Ag needs to be modified. This concern is addressed, as FeMn modified with a degradable Ag-Calcium-Lanthanum (AgCaLa) alloy is investigated. The electrochemical properties and the degradation behavior are determined via a static immersion test. The local differences in electrochemical potential increase the degradation rate (low pH values), and the formation of gaps around the Ag phases (neutral pH values) demonstrates the benefit of the strategy. Nevertheless, the formation of corrosion-inhibiting layers avoids an increased degradation rate under a neutral pH value. The complete bioresorption of the material is possible since the phases of the degradable AgCaLa alloy dissolve after the FeMn matrix. Cell viability tests reveal biocompatibility, and the antibacterial activity of the degradation supernatant is observed. Thus, FeMn modified with degradable AgCaLa phases is promising as a bioresorbable material if corrosion-inhibiting layers can be diminished. author: - first_name: Jan Tobias full_name: Krüger, Jan Tobias id: '44307' last_name: Krüger orcid: 0000-0002-0827-9654 - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Jingyuan full_name: Huang, Jingyuan last_name: Huang - first_name: Viviane full_name: Filor, Viviane last_name: Filor - first_name: Rafael Hernan full_name: Mateus-Vargas, Rafael Hernan last_name: Mateus-Vargas - first_name: Hilke full_name: Oltmanns, Hilke last_name: Oltmanns - first_name: Jessica full_name: Meißner, Jessica last_name: Meißner - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Krüger JT, Hoyer K-P, Huang J, et al.

An intermetallic layer of Al5Fe2 and Al13Fe4 formed at the interface upon annealing above 500 °C. During in-situ annealing in transmission electron microscope, the layer grew towards the steel side of the interface in tongue-like protrusions. A study of furnace-annealed samples revealed, that the bulk growth of the interface phase proceeds towards the aluminium side. The growth towards steel is a surface effect that takes place simultaneously with the bulk growth towards aluminium. At the beginning of the intermetallic layer formation diffusion of Fe into aluminium prevails, afterwards Al atoms diffuse throught the newly formed intermetallic layer towards steel and the whole interface shifts towards aluminium. The kinetics of growth of the intermetallic layer follows parabolic law in both cases, indicating that the growth is governed by diffusion. article_number: '112005' article_type: original author: - first_name: Michaela full_name: Šlapáková, Michaela last_name: Šlapáková - first_name: Barbora full_name: Křivská, Barbora last_name: Křivská - first_name: Klaudia full_name: Fekete, Klaudia last_name: Fekete - first_name: Rostislav full_name: Králík, Rostislav last_name: Králík - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin - first_name: Mykhailo full_name: Stolbchenko, Mykhailo last_name: Stolbchenko - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Šlapáková M, Křivská B, Fekete K, et al.

Ti-6Al-7Nb shows promising improvements, especially regarding biocompatibility, compared with other titanium alloys. The biocompatible features are investigated employing cytocompatibility and antibacterial examinations on Al2O3-blasted and untreated surfaces. The mechanical properties of additively manufactured Ti-6Al-7Nb are evaluated in as-built and heat-treated conditions. Recrystallization annealing (925 °C for 4 h), β annealing (1050 °C for 2 h), as well as stress relieving (600 °C for 4 h) are applied. For microstructural investigation, scanning and transmission electron microscopy are performed. The different microstructures and the mechanical properties are compared. Mechanical behavior is determined based on quasi-static tensile tests and strain-controlled low cycle fatigue tests with total strain amplitudes εA of 0.35%, 0.5%, and 0.8%. The as-built and stress-relieved conditions meet the mechanical demands for the tensile properties of the international standard ISO 5832-11. Based on the Coffin–Manson–Basquin relation, fatigue strength and ductility coefficients, as well as exponents, are determined to examine fatigue life for the different conditions. The stress-relieved condition exhibits, overall, the best properties regarding monotonic tensile and cyclic fatigue behavior. article_number: '122' article_type: original author: - first_name: Maxwell full_name: Hein, Maxwell id: '52771' last_name: Hein orcid: 0000-0002-3732-2236 - first_name: David full_name: Kokalj, David last_name: Kokalj - first_name: Nelson Filipe full_name: Lopes Dias, Nelson Filipe last_name: Lopes Dias - first_name: Dominic full_name: Stangier, Dominic last_name: Stangier - first_name: Hilke full_name: Oltmanns, Hilke last_name: Oltmanns - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Manfred full_name: Kietzmann, Manfred last_name: Kietzmann - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Jessica full_name: Meißner, Jessica last_name: Meißner - first_name: Wolfgang full_name: Tillmann, Wolfgang last_name: Tillmann - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Hein M, Kokalj D, Lopes Dias NF, et al.

For the design of such components, it is crucial to determine their resulting microstructure and mechanical properties. For this purpose, continuous cooling transformation diagrams and deformation continuous cooling transformation diagrams are utilized, however, their curves are strongly influenced by the chemical composition, the initial state and especially the process parameters.\r\n\r\nIn this study, the influence of the process parameters on the transformation kinetics is systematically investigated using an innovative characterization method. The experimental setup allowed a near-process analysis of the transformation kinetics, resulting microstructure and mechanical properties for a specific process route with a reduced number of specimens. A systematic investigation of the effects of different process parameters on the microstructural and mechanical properties made it possible to reveal interactions and independencies between the process parameters in order to design a partial heating or differential cooling process. Furthermore, the implementation of two different cooling conditions, representative of differential cooling in the die relief method with tool-contact and non-contact areas, showed that the soaking duration has a significant influence on the microstructure in the non-contact tool area." article_number: '142780' article_type: original author: - first_name: Alexander full_name: Reitz, Alexander id: '24803' last_name: Reitz orcid: 0000-0001-9047-467X - first_name: Olexandr full_name: Grydin, Olexandr id: '43822' last_name: Grydin - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'Reitz A, Grydin O, Schaper M.

Iron (Fe)-based degradable materials are biocompatible and exhibit good mechanical properties, but their degradation rate is low. Aside from alloying with Manganese (Mn), the creation of phases with high electrochemical potential such as silver (Ag) phases to cause the anodic dissolution of FeMn is promising. However, to enable residue-free dissolution, the Ag needs to be modified. This concern is addressed, as FeMn modified with a degradable Ag-Calcium-Lanthanum (AgCaLa) alloy is investigated. The electrochemical properties and the degradation behavior are determined via a static immersion test. The local differences in electrochemical potential increase the degradation rate (low pH values), and the formation of gaps around the Ag phases (neutral pH values) demonstrates the benefit of the strategy. Nevertheless, the formation of corrosion-inhibiting layers avoids an increased degradation rate under a neutral pH value. The complete bioresorption of the material is possible since the phases of the degradable AgCaLa alloy dissolve after the FeMn matrix. Cell viability tests reveal biocompatibility, and the antibacterial activity of the degradation supernatant is observed. Thus, FeMn modified with degradable AgCaLa phases is promising as a bioresorbable material if corrosion-inhibiting layers can be diminished. article_number: '185' author: - first_name: Jan Tobias full_name: Krüger, Jan Tobias id: '44307' last_name: Krüger orcid: 0000-0002-0827-9654 - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Jingyuan full_name: Huang, Jingyuan last_name: Huang - first_name: Viviane full_name: Filor, Viviane last_name: Filor - first_name: Rafael Hernan full_name: Mateus-Vargas, Rafael Hernan last_name: Mateus-Vargas - first_name: Hilke full_name: Oltmanns, Hilke last_name: Oltmanns - first_name: Jessica full_name: Meißner, Jessica last_name: Meißner - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Krüger JT, Hoyer K-P, Huang J, et al.
