  text: Abstract. Mechanical joints are traditionally analyzed through destructive
    micrograph analysis, which may compromise internal geometry and morphology, as
    evidenced by radial cracks in semi-tubular self-pierce riveting. In contrast,
    industrial X-ray computed tomography (XCT) offers a non-destructive method for
    component diagnosis, providing volumetric insights without damaging the sample
    and enabling dimensional measurement. The DFG-funded Collaborative Research Center
    TRR 285 is exploring XCT's application in assessing mechanical joinability across
    various joining processes and materials, particularly in multi-material systems
    like steel-aluminum joints. XCT faces challenges in accurately capturing multi-material
    compositions, leading to artifacts that complicate interface detection. This research
    aims to validate XCT for joint investigations, yielding quantitative characteristics
    that surpass those from traditional micrograph analysis.

  text: <jats:p>Abstract. Reducing the weight of vehicles can significantly lower
    the energy or fuel consumed and thus the emissions during operation. One possibility
    to assess this is the use of a property adapted multi-material systems containing
    high strength steel, light metals like aluminium or magnesium and fibre reinforced
    plastics. While expanding the number of materials used new challenges arise for
    the production and furthermore the joining technology to manufacture the vehicle
    made of the multi-material systems. One approach to overcome these challenges
    is to use innovative and adaptable joining techniques which allows the manufacturing
    of joints of different material combinations. Extensive research activities on
    the two stage thermo-mechanical joining process with adaptable joining elements
    was able to demonstrate the great potentials in terms of joining dissimilar materials
    with good strength. The previously kinematic and path-based fabrication of auxiliary
    joining elements is modified in this publication to a form-based approach with
    a perspective of establishing an efficient process chain using easily and cheaply
    available rods. Based on the new approach to produce the auxiliary joining elements,
    it can be demonstrated that a reproducible production of the geometry is possible
    for the investigated steel as well as aluminium material. </jats:p>

  text: <jats:p> Lightweight design by using low-density and load-adapted materials
    can reduce the weight of vehicles and the emissions generated during operation.
    However, the usage of different materials requires innovative joining technologies
    with increased versatility. In this investigation, the focus is on describing
    and characterising the failure behaviour of connections manufactured by an innovative
    thermomechanical joining process with adaptable auxiliary joining elements in
    single-lap tensile-shear tests. In order to analyse the failure development in
    detail, the specimens are investigated using in-situ computed tomography (in-situ
    CT). Here, the tensile-shear test is interrupted at points of interest and CT
    scans are conducted under load. In addition, the interrupted in-situ testing procedure
    is validated by comparing the loading behaviour with conventional continuous tensile-shear
    tests. The results of the in-situ investigations of joints with varying material
    combinations clearly describe the cause of failure, allowing conclusions towards
    an improved joint design. </jats:p>

  text: Die weltweit erzeugten Emissionen müssen in allen emittierenden Sektoren signifikant
    gesenkt werden, um die Auswirkungen des Klimawandels zu reduzieren. Dies ist unter
    anderem durch die energieeffiziente Wiederverwertung vorhandener Ressourcen und
    damit der Einstellung einer nachhaltigen Kreislaufwirtschaft möglich. Aufgrund
    der hohen erforderlichen Energiemenge in der primären Herstellung von Aluminium
    existieren hier im Vergleich zu anderen Konstruktionswerkstoffen große Einsparpotentiale.
    Mit dem in dieser Arbeit erforschten reibungsinduzierten Recyclingverfahren (RIR)
    wird eine alternative und energieeffiziente Prozessroute zum direkten Recycling
    von unterschiedlichen Aluminiumschrotten geschaffen. Zur Charakterisierung der
    Prozessroute werden u. a. die Erkenntnisse aus sich gegenseitig unterstützenden
    experimentellen und theoretischen Untersuchungen zu den Vorgängen der der Verdichtung,
    Plastifizierung als auch Extrusion der recycelten Profile dargelegt. Die Einflüsse
    unterschiedlicher Eingangsgrößen wie z. B. der Werkzeuggestaltung oder der Verarbeitung
    unterschiedlicher Legierungen werden zudem zur zukünftigen Auslegung des Prozesses
    erläutert. Aus der abschließenden energetischen Bilanzierung kann geschlossen
    werden, dass aufgrund der geringeren Verarbeitungstemperatur signifikante Energieersparnisse
    bei Verwendung des RIR im Vergleich zu den konventionellen Produktionsstrategien
    erzielt werden können.

  text: <jats:title>Abstract</jats:title><jats:p>The constantly increasing challenges
    of production technology for the economic and resource-saving production of metallic
    workpieces require, among other things, the optimisation of existing processes.
    Forming technology, which is confronted with new challenges regarding the quality
    of the workpieces, must also organise the individual processes more efficiently
    and at the same time more reliably in order to be able to guarantee good workpiece
    quality and at the same time to be able to produce economically. One way to meet
    these challenges is to carry out the forming processes in closed-loop control
    systems using softsensors. Despite the many potential applications of softsensors
    in the field of forming technology, there is still no definition of the term softsensor.
    This publication therefore proposes a definition of the softsensor based on the
    definition of a sensor and the distinction from the observer, which on the one
    hand is intended to stimulate scientific discourse and on the other hand is also
    intended to form the basis for further scientific work. Based on this definition,
    a wide variety of highly topical application examples of various softsensors in
    the field of forming technology are given.</jats:p>

  text: <jats:p>Abstract. Requirements of multi-material construction involve adjustments
    to standard joining techniques. Especially the growing importance of integral
    cast components poses additional engineering challenges for the industry. One
    approach to achieve these goals are adaptable joining elements formed by friction
    spinning. This approach uses friction-induced heat to form customisable joining
    elements to join sheets for different boundary conditions, even for brittle cast
    materials. It is possible to react immediately to adapt to the joining process
    inline and reduce the amount of different joining elements. As the joining partner
    serve casting plates of the aluminium casting alloy EN AC–AlSi9, which is processed
    in the sand casting. Joining hypoeutectic AlSi alloys constitutes a challenge
    because the brittle character of these cause cracks in the joint during conventional
    mechanical joining. Furthermore, the friction-induced heat of the novel joining
    process causes a finer microstructure in the hypoeutectic AlSi9 casting alloy.
    In particular, the eutectic Si is more fine-grained, resulting in higher joint
    ductility. This study indicates the joining suitability of a hypoeutectic aluminium
    casting alloy in combination with adaptive manufactured additional joining elements.
    Here, various mechanical and microstructural investigations validate the influence
    of the thermomechanical joining technique. In conclusion, the potential of this
    joining process is presented regarding the joinability of cast aluminium components.

  text: <jats:p>Consistent lightweight construction in the area of vehicle manufacturing
    requires the increased use of multi-material combinations. 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

    alloys is challenging as their brittle character leads to cracks in the joint
    during conventional mechanical joining. To solve this, the frictional heat of

  text: <jats:p>Abstract. In order to reduce global energy consumption in production
    and industry along with the associated CO2 emissions, existing resources must
    be used more efficiently. This includes the energy-efficient and comprehensive
    recycling of a wide range of metals. Especially for the production of aluminium,
    there is a large potential for saving energy using efficient recycling processes.
    With regard to the recycling of aluminium studies have shown that solid-state
    recycling processes are significantly more efficient considering the used energy
    and resources compared to the conventional, smelting-metallurgical recycling process.
    In this paper, the direct and energy-efficient friction-induced recycling process
    (FIRP) based on the conform process is further described and analysed in terms
    of the temperature-property relationships. For this purpose, the influence of
    the processing temperature on the microstructure and properties of the recycled
    semi-finished products is investigated using the toll system that enables an ECAP
    forming. Specific sections of the (in theory) infinite, recycled semi-finished
    product are taken and analysed at different process temperatures of the solid
    state recycling process. Based on these sections, the properties in terms of mechanical
    hardness, strength, ductility and grain size are analysed and a degressive relationship
    between process temperature and mechanical hardness up to a temperature of 270
    °C can be shown. Applying the Hall-Petch relationship, it is analysed whether
    there is a correlation between the strength and the microstructure in the form
    of the grain size. </jats:p>

  text: <jats:p>The demands on joining technology are constantly increasing due to
    the consistent lightweight construction and the associated increasing material
    mix. To meet these requirements, the adaptability of the joining processes must
    be improved to be able to process different material combinations and to react
    to challenges caused by deviations in the process chain. One example of a highly
    adaptable process due to the two-step process sequence is thermomechanical joining
    with Friction Spun Joint Connectors (FSJCs) that can be individually adapted to
    the joint. In this paper, the potentials of the adaption in the two-stage joining
    process with aluminium auxiliary joining elements are investigated. To this end,
    it is first investigated whether a thermomechanical forming process can be used
    to achieve a uniform and controlled manufacturing regarding the process variable
    of the temperature as well as the geometry of the FSJC. Based on the successful
    proof of the high and good repeatability in the FSJC manufacturing, possibilities,
    and potentials for the targeted influencing of the process and FSJC geometry are
    shown, based on an extensive variation of the process input variables (delivery
    condition and thus mechanical properties of the raw parts as well as the process
    parameters of rotational speed and feed rate). Here it can be shown that above
    all, the feed rate of the final forming process has the strongest influence on
    the process and thus also offers the strongest possibilities for influencing it.</jats:p>

  text: Due to current global challenges regarding energy security as well as climate
    change the importance of preserving the nature and all available resources is
    steadily increasing. In order to achieve the energy-saving and climate targets,
    it is not only necessary to develop new processes and processing possibilities,
    but also to optimise known process chains with regard to energy and resource efficiency
    in the area of production technology. Here, the recycling of supposed production
    waste represents an opportunity to save energy. In addition to the conventional
    and smelting metallurgical recycling process, extensive research activities have
    therefore been carried out for alternative solid-state recycling processes. One
    example is the friction-induced recycling process, which has been used in past
    studies to demonstrate the energy- and resource-efficient production of semi-finished
    products from aluminium scrap such as chips. In addition, properties like chemical
    composition and strength can be adjusted locally and in terms of processing time.
    This can be used to improve the versatility of further processing steps.

  text: <jats:title>Abstract</jats:title><jats:p>Efforts to enhance sustainability
    in all areas of life are increasing worldwide. 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.</jats:p>

  text: <jats:p>Modern forming processes often allow today the efficient production
    of complex parts. In order to increase the sustainability of forming processes
    it would be favorable if the forming of workpieces becomes possible using production
    waste. At the Chair of Forming and Machining Technology of the Paderborn University
    (LUF) research is presently conducted with the overall goal to produce workpieces
    directly from secondary aluminum (e.g., powder and chips). Therefore, friction-based
    forming processes like friction spinning (or cognate processes) are used due to
    their high efficiency. As a pre-step, the production of semi-finished parts was
    the subject of accorded research work at the LUF. Therefore, a friction-based
    hot extrusion process was used for the full recycling or rework of aluminum chips
    into profiles. Investigations of the recycled semi-finished products show that
    they are comparable to conventionally produced semi-finished products in terms
    of dimensional stability and shape accuracy. An analysis of the mechanical properties
    of hardness and tensile strength shows that a final product with good and homogeneously
    distributed properties can be produced. Furthermore, significant correlations
    to the friction spinning process could be found that are useful for the above-mentioned
    direct part production from secondary aluminum.</jats:p>
