text: Clinching is the manufacturing process of joining two or more metal sheets
under high plastic deformation by form and force closure without thermal support
and auxiliary parts. Clinch connections are applicable to difficult-to-join hybrid
material combinations, such as steel and aluminum. Therefore, this technology
is interesting for the application of AISI 304 components, as this material is
widely used as a highly formable sheet material. A characteristic feature of AISI
304 is its metastability, i.e., the face-centered cubic (fcc) γ-austenite can
transform into a significantly stronger body-centered cubic (bcc) α’-martensite
under plastic deformation. This work investigates the effect of heat treatment—a
process that involves the formation of an oxidation layer on the sheet surface—on
the forming process during joining and the resulting mechanical properties of
clinch joints made from AISI 304. For this purpose, different joints made from
non-heat treated and heat-treated sheets were examined using classical metallography
and advanced SEM techniques, accompanied by further investigations, such as hardness
and feritscope measurements. The shear tensile strength was determined, and the
fracture behavior of the samples was investigated. Clear influences of heat-treatment-induced
surface roughness on the joint geometry and strength were observed.

text: The trend towards lightweight design, driven by increasingly stringent emission
targets, poses challenges to conventional joining processes due to the different
mechanical properties of the joining partners used to manufacture multi-material
systems. For this reason, new versatile joining processes are in demand for joining
dissimilar materials. In this regard, pin joining with cold extruded pin structures
is a relatively new, two-stage joining process for joining materials such as high-strength
steel and aluminium as well as steel and fibre-reinforced plastic to multi-material
systems, without the need for auxiliary elements. Due to the novelty of the process,
there are currently only a few studies on the robustness of this joining process
available. Thus, limited statements on the stability of the joining process considering
uncertain process conditions, such as varying material properties or friction
values, can be provided. Motivated by this, the presented work investigates the
influence of different uncertain process parameters on the pin extrusion as well
as on the joining process itself, carrying out a systematic robustness analysis.
Therefore, the methodical approach covers the complete process chain of pin joining,
including the load-bearing capacity of the joint by means of numerical simulation
and data-driven methods. Thereby, a deeper understanding of the pin joining process
is generated and the versatility of the novel joining process is increased. Additionally,
the provision of manufacturing recommendations for the forming of pin joints leads
to a significant decrease in the failure probability caused by ploughing or buckling
effects.

text: Deformation of continuous fibre reinforced plastics during thermally-assisted
forming or joining processes leads to a change of the initial material structure.
The load behaviour of composite parts strongly depends on the resultant material
structure. The prediction of this material structure is a challenging task and
requires a deep knowledge of the material behaviour above melting temperature
and the occurring complex forming phenomena. Through this knowledge, the optimisation
of manufacturing parameters for a more efficient and reproducible process can
be enabled and are in the focus of many investigations. In the present paper,
a simplified pultrusion test rig is developed and presented to investigate the
deformation behaviour of a thermoplastic semi-finished fiber product in a forming
element. Therefore, different process parameters, like forming element temperature,
pulling velocity as well as the forming element geometry, are varied. The deformation
behaviour in the forming zone of the thermoplastic preimpregnated continuous glass
fibre-reinforced material is investigated by computed tomography and the resultant
pulling forces are measured. The results clearly show the correlation between
the forming element temperature and the resulting forces due to a change in the
viscosity of the thermoplastic matrix and the resulting fiber matrix interaction.
In addition, the evaluation of the measurement data shows which forming forces
are required to change the shape of the thermoplastic unidirectional material
with a rectangular cross-section to a round one.

text: Pin extrusion is a common process to realise pin structures in different geometrical
dimensions for a subsequent joining operation. Nevertheless, the process of pin
extrusion offers process limits regarding sheet thinning as a consequence of the
punch penetration depth into the sheet. Thereby, cracks at the residual sheet
thickness can occur during strength tests, resulting in a failure of the complete
joint due to severe thinning. Therefore, measures have to be taken into account
to reduce the thinning. One possibility is the application of orbital formed tailored
blanks with a local material pre-distribution, which allows a higher sheet thickness
in the desired area. Within this contribution, the novel approach of a process
combination of orbital forming and pin extrusion is investigated. To reveal the
potential of a local material pre-distribution, conventional specimens are compared
with previously orbital formed components. Relevant parameters such as the residual
sheet thickness, the pin height as well as the average hardness values are compared.
The results show a significant positive influence of a local material pre-distribution
on the residual sheet thickness as well as the resulting pin height. Furthermore,
the strain hardening during orbital forming can be seen as an additional advantage.
To conclude the results, the process limits of conventional pin extrusion can
be expanded significantly by the application of specimens with a local material
pre-distribution.

text: This article presents the application and evaluation of a cantilever with
integrated sensing and actuation as part of an atomic force microscope (AFM) with
an adjustable probe direction, which is integrated into a nano measuring machine
(NMM-1). The AFM, which is operated in closed-loop intermittent contact mode,
is based on two rotational axes that enable the adjustment of the probe direction
to cover a complete hemisphere. The axes greatly enlarge the metrology frame of
the measuring system by materials with a comparatively high coefficient of thermal
expansion, which ultimately limits the achievable measurement uncertainty of the
measuring system. Thus, to reduce the thermal sensitivity of the system, the redesign
of the rotational kinematics is mandatory. However, in this article, some preliminary
investigations on the application of a self-sensing cantilever with an integrated
micro heater for its stimulation will be presented. In previous investigations,
a piezoelectric actuator has been applied to stimulate the cantilever. However,
the removal of the piezoelectric actuator, which is enabled by the application
of a cantilever with an integrated micro heater, promises an essential simplification
of the sensor holder. Thus, in the future it might be possible to use materials
with a low coefficient of thermal expansion, which are often difficult to machine
and therefore only allow for rather simple geometries. Furthermore, because of
the creepage of piezoelectric actuators, their removal from the metrology frame
might lead to improved metrological characteristics. As will be shown, there are
no significant differences between the two modes of actuation. Therefore, the
redesigned rotational system will be based on the cantilever with integrated sensing
and actuation.

text: Joining by forming operations presents powerful and complex joining techniques.
Clinching is a well-known joining process for use in sheet metalworking. Currently,
clinched joints are focusing on mechanically enhanced connections. Additionally,
the demand for integrating electrical requirements to transmit electrical currents
will be increased in the future. This integration is particularly important, for
instance, in the e-mobility sector. It enables connecting battery cells with electrical
joints of aluminum and copper. Systematic use of the process-specific advantages
of this joining method opens up the possibility to find and create electrically
optimized connections. The optimization for the transmission of electrical currents
will be demonstrated for clinched joints by adapting the tool geometry and the
clinched joint design. Based on a comparison of the electrical joint resistance,
the limit use temperature is defined for the joining materials used based on the
microstructural condition and the aging condition due to artificial aging. As
a result of the investigations carried out, reliable current transmission at a
constant conductor temperature of up to 120 °C can be achieved for clinched copper–copper
joints. In the case of pure aluminum joints and mixed joints of aluminum and copper,
long-term stable current transmission can be ensured up to a conductor temperature
of 100 °C.

text: A virtual test setup for investigating single fibres in a transverse shear
flow based on a parallel-plate rheometer is presented. The investigations are
carried out to verify a numerical representation of the fluid–structure interaction
(FSI), where Arbitrary Lagrangian–Eulerian (ALE) and computational fluid dynamics
(CFD) methods are used and evaluated. Both are suitable to simulate flexible solid
structures in a transverse shear flow. Comparative investigations with different
model setups and increasing complexity are presented. It is shown, that the CFD
method with an interface-based coupling approach is not capable of handling small
fibre diameters in comparison to large fluid domains due to mesh dependencies
at the interface definitions. The ALE method is more suited for this task since
fibres are embedded without any mesh restrictions. Element types beam, solid,
and discrete are considered for fibre modelling. It is shown that the beam formulation
for ALE and 3D solid elements for the CFD method are the preferred options.

text: Clinching is a cost efficient method for joining components in series production.
To assure the clinch point’s quality, the force displacement curve during clinching
or the bottom thickness are monitored. The most significant geometrical characteristics
of the clinch point, neck thickness and undercut, are usually tested destructively
by microsectioning. However, micrograph preparation goes ahead with a resetting
of elastic deformations and crack-closing after unloading. To generate a comprehensive
knowledge of the clinch point’s inner geometry under load, in-situ computed tomography
(CT) and acoustic testing (TDA) can be combined. While the TDA is highly sensitive
to the inner state of the clinch point, it could detect critical events like crack
development during loading. If such events are indicated, the loading process
is stopped and a stepped in-situ CT of the following crack and deformation development
is performed. In this paper, the concept is applied to the process of clinching
itself, providing a detailed three-dimensional insight in the development of the
joining zone. A test set-up is used which allows a stepwise clinching of two aluminium
sheets EN AW 6014. Furthermore, this set-up is positioned within a CT system.
In order to minimize X-ray absorption, a beryllium cylinder is used within the
set-up frame and clinching tools are made from Si3N4. The actuator and sensor
necessary for the TDA are integrated in the set-up. In regular process steps,
the clinching process is interrupted in order to perform a TDA and a CT scan.
In order to enhance the visibility of the interface, a thin tin layer is positioned
between the sheets prior clinching. It is shown, that the test-set up allows a
monitoring of the dynamic behaviour of the specimen during clinching while the
CT scans visualize the inner geometry and material flow non-destructively.

text: Mechanical clinching is used to create lightweight hybrid structures. In order
to estimate the service life of clinched components, its fatigue properties need
to be known under different mechanical loading conditions. In addition to fatigue,
corrosion is another factor that affects the fatigue life of clinched joints.
In the literature, many corrosion and high-cycle fatigue damage models exist.
However, little is known about how both phenomena interact in clinched joints.
In this article, the influence of galvanic corrosion on clinched EN AW-6014/HCT590X + Z
sheets on the fatigue life is investigated by means of numerical simulations and
experimental results. An accurate prediction of the Wöhler lines of non-corroded
and pre-corroded clinched specimens is shown.

text: "Abstract\r\n The round robin
test investigated the reliability users can expect for AlSi10Mg additive manufactured
specimens by laser powder bed fusion through examining powder quality, process
parameter, microstructure defects, strength and fatigue. Besides for one outlier,
expected static material properties could be found. Optical microstructure inspection
was beneficial to determine true porosity and porosity types to explain the occurring
scatter in properties. Fractographic analyses reveal that the fatigue crack propagation
starts at the rough as-built surface for all specimens. Statistical analysis of
the scatter in fatigue using statistical derived safety factors concludes that
at a stress of 36.87 MPa the fatigue limit of 107 cycles
could be reached for all specimen with a survival probability of 99.999 %."

the fabrication of micron-wide tungsten silicide superconducting nanowire single-photon
detectors on a silicon substrate using laser lithography. We show saturated internal
detection efficiencies with wire widths ranging from 0.59 µm
to 1.43 µm under illumination at 1550 nm. We demonstrate
both straight wires, as well as meandered structures. Single-photon sensitivity
is shown in devices up to 4 mm in length. Laser-lithographically written devices
allow for fast and easy structuring of large areas while maintaining a saturated

text: Background. Clinching is a conventional cold forming process in which two
or more sheets can be joined without auxiliary parts. A pre-forming of the parts
to be joined, which is introduced by previous manufacturing steps, has an influence
on the joining result. When considering the suitability for joining with regard
to the formability of the materials, the influence of the preforming steps must
be taken into account. The influences of strain hardening and sheet thickness
on the joining properties must be investigated. In this context, a Finite Element
Method (FEM) based metamodel analysis of the clinching process was carried out
in [1] to investigate the robustness of the clinching process with respect to
the different material pre-strains. In [2], the method was extended to the load
bearing simulation.Procedure. The metamodel from preliminary work based on various
FE models, which predicts the load-bearing capacity of a clinched joint influenced
by pre-straining, is compared here with experimental data and the accuracy of
the metamodel prediction is discussed. For this purpose an experimental procedure
was further develop which allows the preforming of metal sheets from which joining
specimens can be separated with a certain degree of unidirectional deformation.
In the study, the procedure for preparing the joint specimens and the results
of the loading tests are presented. Different possible relevant pre-strain combinations
are investigated and compared with the simulation results, to validate the FE
models and choose suitable metamodel.

text: "Abstract\r\n Lithium niobate
is a promising platform for integrated quantum optics. In this platform, we aim
to efficiently manipulate and detect quantum states by combining superconducting
single photon detectors and modulators. The cryogenic operation of a superconducting
single photon detector dictates the optimisation of the electro-optic modulators
under the same operating conditions. To that end, we characterise a phase modulator,
directional coupler, and polarisation converter at both ambient and cryogenic
temperatures. The operation voltage \r\n \r\n \r\n \r\n V\r\n
\ \r\n π\r\n
\ \r\n /\r\n
\ \r\n 2\r\n
\ \r\n \r\n
\ \r\n \r\n of these
modulators increases, due to the decrease in the electro-optic effect, by 74%
for the phase modulator, 84% for the directional coupler and 35% for the polarisation
converter below 8.5\r\n \r\n \r\n \r\n K\r\n \r\n \r\n
\ \r\n .
The phase modulator preserves its broadband nature and modulates light in the
characterised wavelength range. The unbiased bar state of the directional coupler
changed by a wavelength shift of 85\r\n \r\n \r\n \r\n n\r\n m\r\n
\ \r\n \r\n \r\n while cooling
the device down to 5\r\n \r\n \r\n \r\n K\r\n \r\n \r\n
\ \r\n .
The polarisation converter uses periodic poling to phasematch the two orthogonal
polarisations. The phasematched wavelength of the utilised poling changes by 112\r\n
\ \r\n
\ \r\n \r\n n\r\n m\r\n
\ \r\n \r\n \r\n when cooling

have been proposed as intrinsically nanoscaled two-dimensional electron gases
(2DEGs) because of their significant conductivity. Here, we quantify these 2DEG
properties through dedicated Hall transport measurements in van der Pauw 4-point
geometry, finding the electron mobility to reach around 400 cm2 (V s)^{−1}, while
the two-dimensional charge density amounts to 7 × 103 cm^{–2}. We underline the
necessity to take into account the thermal and geometrical misalignment offset
voltages by evaluating the Hall resistance under magnetic field sweeps; otherwise,
errors of several hundred percent in the derived transport parameters can occur.

text: AlSi casting alloys combine excellent castability with high strength. Hence,
this group of alloys is often used in the automotive sector. The challenge for
this application is the brittle character of these alloys which leads to cracks
during joint formation when mechanical joining technologies are used. A rise in
ductility can be achieved by a considerable increase in the solidification rate
which results in grain refinement. High solidification rates can be realized in
twin–roll casting (TRC) by water-cooled rolls. Therefore, a hypoeutectic EN AC–AlSi9
(for European Norm - aluminum cast product) is manufactured by the TRC process
and analyzed. Subsequently, joining investigations are performed on castings in
as-cast and heat-treated condition using the self-piercing riveting process considering
the joint formation and the load-bearing capacity. Due to the fine microstructure,
the crack initiation can be avoided during joining, while maintaining the joining
parameters, especially by specimens in heat treatment conditions. Furthermore,
due to the extremely fine microstructure, the load-bearing capacity of the joint
can be significantly increased in terms of the maximum load-bearing force and
the energy absorbed.

text: In many manufacturing areas, multi-material designs are implemented
in which individual components are joined together to form complex structures
with numerous joints. 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.
