text: 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
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.

text: 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.

text: Abstract. Friction-spinning as an innovative incremental forming process
enables large degrees of deformation in tube and sheet metal-forming due to a
self-induced heat generation in the forming zone. This paper presents new process
designs for energy and resource-efficient forming of gas cylinders by friction-spinning
without the use of an external heat supply. The self-generated heat enables friction-spinning
process to reduce the energy demand in the manufacture of gas cylinders, which
are usually manufactured with external heat (mostly fossil fuels), by 95 %. Typical
gas cylinder contours, such as flattened and spherical bottom ends and cylinder
necks, are manufactured by friction-spinning of AW 6060 tubular profiles with
specifically designed tool path strategies. It is shown that friction-spinning
enables the manufacture of typical gas cylinder contours with sufficient wall
thickness and the required gas tightness without the input of external heat. Thus,
this process can contribute to an increase in the energy and resource efficiency
of forming processes.

text: Abstract. The combination of incremental sheet metal forming and high-speed
forming offers new possibilities for flexible forming processes in the production
of large sheet metal components of increased complexity with relatively low forming
energies. In this paper, the general feasibility and process differences between
the pulse-driven high-speed forming technologies of electrohydraulic and electromagnetic
forming were investigated. An example component made of EN AW 6016 aluminum sheet
metal was thus formed incrementally by both processes and the forming result evaluated
by an optical 3D measurement system. For this purpose, a forming strategy for
electromagnetic incremental forming (EMIF) was developed, tested and adapted to
the electrohydraulic incremental forming process (EHIF). The discharge energy,
the tool displacement and the pressure field of the forming zone were determined
as relevant parameters for the definition of an adequate tool path strategy. It
was found that the EHIF process is less affected by larger distances between the
tool and the blank, while this is a critical variable for force application to
the component during EMIF. On the other hand, the more uniform pressure distribution
of the EMIF process is advantageous for forming large steady component areas.

text: The pressure fields generated by two simultaneous discharges have
not been investigated on any notable scale for the electrohydraulic impulse forming
method. In this study, the synchronicity of two discharges is ensured by the sequential
connection of two wires mounted in two spark gaps in a common volume of liquid.
The objective is to experimentally confirm the equilibrium of the energies evolved
in two spark gaps by means of pressure measurements. In addition, multipoint membrane
pressure gauges demonstrated the feasibility of easily recording detailed pressure
maps. Based on the membrane deformation mechanism and material strengthening under
static and impulse conditions, the processing procedure is further developed so
as to achieve better accuracy in the determination of pressure field parameters.
The practical equality of the pressure fields on the left and right halves of
the flat-loaded area confirms the equality of energies evolved in the two spark
gaps. The direct shock waves create zones with the most intensive loading. These
results provide a basis for the development of new electrohydraulic technologies
involving the application of two simultaneous discharges with equal energy and
pressure parameters.

text: 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.

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: "Zusammenfassung\r\n Aufgrund
aktueller Transformationsprozesse kommt der automatisierten und ressourceneffizienten
Fertigung hochfester Leichtbauteile eine steigende Bedeutung zu, beispielsweise
im Flugzeug- und Fahrzeugbau. Für kleine Losgrößen bietet sich hier insbesondere
das Fertigungsverfahren des Drückwalzens an. Der konventionelle, industriell genutzte
Drückwalzprozess stößt allerdings aufgrund der Prozesskomplexität hinsichtlich
der Reproduzierbarkeit an seine Grenzen. Dies wird in der Praxis teilweise durch
personengebundenes Erfahrungswissen kompensiert. Auch ist es nicht möglich, Bauteileigenschaften
definiert einzustellen. Aus diesem Grund bietet der Einsatz einer neuartigen Eigenschaftsregelung
Chancen zur Weiterentwicklung des Fertigungsprozesses und die Möglichkeit zur
Prozessautomatisierung. Hier werden die Werkzeugbahnen abhängig einer Online-Eigenschaftsmessung
über eine zusätzliche Reglerkaskade manipuliert. Die Entwicklung einer solchen
Eigenschaftsregelung erfordert den Einsatz geeigneter, modellbasierter Entwurfsmethoden.
In diesem Beitrag wird daher ein regelungstechnisches Systemmodell für das Drückwalzen
metastabiler austenitischer Edelstähle vorgestellt. Das Simulationsmodell weist
aufgrund seiner Echtzeitfähigkeit neben dem Einsatz als reines Entwurfsmodell
weitere Nutzungsmöglichkeiten z.B. in Beobachtern auf und grenzt sich somit von
domänenspezifischen Simulationstools wie der FEM ab."

text: Abstract. Climate change, rare resources and industrial transformation
processes lead to a rising demand of multi-complex lightweight forming parts,
especially in aerospace and automotive sectors. In these industries, flow forming
is often used to produce cylindrical forming parts by reducing the wall thickness
of tubular semifinished parts, e.g. for the production of hydraulic cylinders
or gear shafts. The complexity and functionality of flow forming workpieces could
be significantly increased by locally graded microstructure and geometry structures.
This enables customized complex hardness distributions at wear surfaces or magnetic
QR codes for a unique, tamper-proof product identification. The production of
those complex, 2D (axial and angular) graded forming parts currently depicts a
great challenge for the process and requires new solutions and strategies. Hence,
this paper proposes a novel control strategy that includes online measurements
from an absolute encoder to determine the angular workpiece position. Workpieces
of AISI 304L stainless steel with 2D-graded structures are successfully manufactured
using this new strategy and analyzed regarding the possible accuracy and resolution
of the gradation. At this point, a dependency of the gradations on the sensor
and actuator dynamics, accuracy and geometry could be noted. It is further evaluated
how the control strategy could be extended by an observer-based closed-loop property
control approach to enhance the accuracy of the suggested strategy.

text: AbstractEfforts 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.

text: Pillow-plate heat exchangers (PPHEs) represent a suitable alternative
to conventional shell-and-tube and plate heat exchangers. The inherent waviness
of their channels promotes fluid mixing in the boundary layers and facilitates
heat transfer. The overall thermo-hydraulic performance of PPHEs can further be
enhanced by applying secondary surface structuring, thus increasing their competitiveness
against conventional heat exchangers. In this work, various secondary structures
applied on the PPHE surface were studied numerically to explore their potential
to enhance near-wall mixing. Computational fluid dynamics (CFD) simulations of
single-phase turbulent flow in the outer PPHE channel were performed and pressure
drop, heat transfer coefficients, and overall thermo-hydraulic efficiency were
determined. The simulation results clearly demonstrate a positive impact of secondary
structuring on heat transfer in PPHEs.

text: Mechanical joining technologies are increasingly used in multi-material lightweight
constructions and offer opportunities to create versatile joining processes due
to their low heat input, robustness to metallurgical incompatibilities and various
process variants. They can be categorised into technologies which require an auxiliary
joining element, or do not require an auxiliary joining element. A typical example
for a mechanical joining process with auxiliary joining element is self-piercing
riveting. A wide range of processes exist which are not requiring an auxiliary
joining element. This allows both point-shaped (e.g., by clinching) and line-shaped
(e.g., friction stir welding) joints to be produced. In order to achieve versatile
processes, challenges exist in particular in the creation of intervention possibilities
in the process and the understanding and handling of materials that are difficult
to join, such as fiber reinforced plastics (FRP) or high-strength metals. In addition,
predictive capability is required, which in particular requires accurate process
simulation. Finally, the processes must be measured non-destructively in order
to generate control variables in the process or to investigate the cause-effect
relationship. This paper covers the state of the art in scientific research concerning
mechanical joining and discusses future challenges on the way to versatile mechanical
joining processes.

text: Friction-spinning as an innovative incremental forming process enables
large degrees of deformation in the field of tube and sheet metal forming due
to a self-induced heat generation in the forming zone. This paper presents a new
tool and process design with a driven tool for the targeted adjustment of residual
stress distributions in the friction-spinning process. Locally adapted residual
stress depth distributions are intended to improve the functionality of the friction-spinning
workpieces, e.g. by delaying failure or triggering it in a defined way. The new
process designs with the driven tool and a subsequent flow-forming operation are
investigated regarding the influence on the residual stress depth distributions
compared to those of standard friction-spinning process. Residual stress depth
distributions are measured with the incremental hole-drilling method. The workpieces
(tubular part with a flange) are manufactured using heat-treatable 3.3206 (EN-AW
6060 T6) tubular profiles. It is shown that the residual stress depth distributions
change significantly due to the new process designs, which offers new potentials
for the targeted adjustment of residual stresses that serve to improve the workpiece
properties.

text: Friction-spinning as an innovative incremental forming process enables
high degrees of deformation in the field of tube and sheet metal forming due to
self-induced heat generation in the forming area. The complex thermomechanical
conditions generate non-uniform residual stress distributions. In order to specifically
adjust these residual stress distributions, the influence of different process
parameters on residual stress distributions in flanges formed by the friction-spinning
of tubes is investigated using the design of experiments (DoE) method. The feed
rate with an effect of −156 MPa/mm is the dominating control parameter for residual
stress depth distribution in steel flange forming, whereas the rotation speed
of the workpiece with an effect of 18 MPa/mm dominates the gradient of residual
stress generation in the aluminium flange-forming process. A run-to-run predictive
control system for the specific adjustment of residual stress distributions is
proposed and validated. The predictive model provides an initial solution in the
form of a parameter set, and the controlled feedback iteratively approaches the
target value with new parameter sets recalculated on the basis of the deviation
of the previous run. Residual stress measurements are carried out using the hole-drilling
method and X-ray diffraction by the cosα-method.
