text: Resistance spot‐welded joints containing press‐hardened steels are
seen to exhibit a fracture mode called total dome failure, where the weld nugget
completely separates from one steel sheet along the weld nugget edge. The effect
of weld nugget shape and material property gradients is studied based on damage
mechanics modeling and experimental validation to shed light on the underlying
influencing factors. For a three‐steel‐sheet spot‐welded joint combining DP600
(1.5 mm)–CR1900T (1.0 mm)–CR1900T (1.0 mm), experiments under shear loading reveal
that fracture occurs in the DP600 sheet along the weld nugget edge. In subsequent
numerical simulation studies with damage mechanics models whose parameters are
independently calibrated for every involved material configuration, three variations
of the geometrical joint configuration are considered—an approximation of the
real joint, one variation with a steeper weld nugget shape, and one variation
with a less pronounced gradient between weld nugget material and heat‐affected
zone material properties. The results of the finite‐element simulations show that
a shallower weld nugget and a more pronounced material gradient lead to a faster
increase of plastic strain at the edge of the weld nugget and promote the occurrence
of total dome failure.

text: AbstractIn Konstruktionen des Landmaschinenbaus
aus dickeren Blechen (ca. 3–10 mm) findet die Klebtechnik bislang nur wenig Anwendung,
obwohl sie in anderen Einsatzgebieten bereits ein etabliertes Fügeverfahren darstellt
und viele Vorteile gegenüber anderen Fügeverfahren bietet, da es bisher an Regelwerken
bei der Auslegung derartiger Verbindungen fehlt. Ein wesentliches Kriterium bei
der Auslegung von Verbindungen im Landmaschinenbau ist die Ermüdungsfestigkeit
aufgrund der langen Nutzungsphase der Produkte und der in der Landtechnik vorherrschenden
Belastungscharakteristika. Geklebte Verbindungen weisen ein hervorragendes Verhalten
bei zyklischer Belastung auf. Die steigenden Anforderungen im Hinblick auf Ressourceneffizienz
und Leichtbau führen zu einem Umdenken, da durch den vermehrten Einsatz höherfester
Stahlwerkstoffe in Kombination mit der Klebtechnik dieses als umsetzbar erscheint.
Ziel ist die Entwicklung einer Methode zur Auslegung geklebter Verbindungen in
Konstruktionen mit höherfesten Stahlwerkstoffen in Anlehnung an die FKM‐Richtlinie.
Die betriebsrelevanten Beanspruchungen der Landtechnik werden analysiert und an
speziellen Probekörpern untersucht. Dabei werden sowohl die mechanischen, thermischen
und medialen Einflussfaktoren als auch der Einfluss der Klebfugengeometrie und
von Betriebslastenkollektiven untersucht. Die Erkenntnisse werden in einer KMU‐relevanten
Vorgehensweise zur Ermittlung von Abminderungsfaktoren zusammengefasst, wodurch
die Auslegung der Bauteilfestigkeit sowohl statisch als auch dynamisch möglich
ist.

text: "AbstractFeCo alloys are important materials
used in pumps and motors in the offshore oil and gas drilling industry. These
alloys are subjected to marine environments with a high NaCl concentration, therefore,
corrosion and catastrophic failure are anticipated. So, the surface dissolution
of additively manufactured FeCo samples is investigated in a quasi-in
situ manner, in particular, the pitting corrosion in 5.0 wt pct
NaCl solution. The local dissolution of the same sample region is monitored after
24, 72, and 168 hours. Here, the formation of rectangular and circular pits of
ultra-fine dimensions (less than 0.5 µm) is observed
with increasing immersion time. In addition, the formation of a corrosion-inhibiting
surface layer is detected on the sample surface. Surface dissolution leads to
a change in the surface structure, however, no change in grain shape or grain
size is noticed. The surface topography after local dissolution is correlated
to the grain orientation. Quasi-in situ analysis shows
the preferential dissolution of high-angle grain boundaries (HAGBs) leading to
a change in the fraction of HAGBs and low-angle grain boundaries fraction (LAGBs).
For the FeCo sample, a potentiodynamic polarisation test reveals a corrosion potential
(Ecorr) of − 0.475 V referred to the standard hydrogen electrode
(SHE) and a corrosion exchange current density (icorr) of
0.0848 A/m2. Furthermore, quasi-in situ
experiments showed that grains oriented along certain crystallographic directions
are corroding more compared to other grains leading to a significant decrease
in the local surface height. Grains with a plane normal close to the $$\\langle
{1}00\\rangle$$\r\n
\ \r\n ⟨\r\n 100\r\n
\ ⟩\r\n \r\n
direction reveal lower surface dissolution and higher corrosion resistance, whereas
planes normal close to the $$\\langle
{11}0\\rangle$$\r\n
\ \r\n ⟨\r\n 110\r\n
\ ⟩\r\n \r\n
direction and the $$\\langle
{111}\\rangle$$\r\n
\ \r\n ⟨\r\n 111\r\n
\ ⟩\r\n \r\n
direction exhibit a higher surface dissolution."

text: 'AbstractHeated tool butt welding is a method
often used for joining thermoplastics, especially when the components are made
out of different materials. The quality of the connection between the components
crucially depends on a suitable choice of the parameters of the welding process,
such as heating time, temperature, and the precise way how the parts are then
welded. Moreover, when different materials are to be joined, the parameter values
need to be tailored to the specifics of the respective material. To this end,
in this paper, three approaches to tailor the parameter values to optimize the
quality of the connection are compared: a heuristic by Potente, statistical experimental
design, and Bayesian optimization. With the suitability for practice in mind,
a series of experiments are carried out with these approaches, and their capabilities
of proposing well-performing parameter values are investigated. As a result, Bayesian
optimization is found to yield peak performance, but the costs for optimization
are substantial. In contrast, the Potente heuristic does not require any experimentation
and recommends parameter values with competitive quality.'

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: 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: "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: During resistance spot welding of zinc-coated advanced high-strength
steels (AHSSs) for automotive production, liquid metal embrittlement (LME) cracking
may occur in the event of a combination of various unfavorable influences. In
this study, the interactions of different welding current levels and weld times
on the tendency for LME cracking in third-generation AHSSs were investigated.
LME manifested itself as high-penetration cracks around the circumference of the
spot welds for welding currents closely below the expulsion limit. At the same
time, the observed tendency for LME cracking showed no direct correlation with
the overall heat input of the investigated welding processes. To identify a reliable
indicator of the tendency for LME cracking, the local strain rate at the origin
of the observed cracks was analyzed over the course of the welding process via
finite element simulation. While the local strain rate showed a good correlation
with the process-specific LME cracking tendency, it was difficult to interpret
due to its discontinuous course. Therefore, based on the experimental measurement
of electrode displacement during welding, electrode indentation velocity was proposed
as a descriptive indicator for quantifying cracking tendency.

text: The adaptive joining process employing friction-spun joint connectors
(FSJC) is a promising method for the realization of adaptable joints and thus
for lightweight construction. In addition to experimental investigations, numerical
studies are indispensable tools for its development. Therefore, this paper includes
an analysis of boundary conditions for the spatial discretization and mesh modeling
techniques, the material modeling, the contact and friction modeling, and the
thermal boundary conditions for the finite element (FE) modeling of this joining
process. For these investigations, two FE models corresponding to the two process
steps were set up and compared with the two related processes of friction stir
welding and friction drilling. Regarding the spatial discretization, the Lagrangian
approach is not sufficient to represent the deformation that occurs. The Johnson-Cook
model is well suited as a material model. The modeling of the contact detection
and friction are important research subjects. Coulomb’s law of friction is not
adequate to account for the complex friction phenomena of the adaptive joining
process. The thermal boundary conditions play a decisive role in heat generation
and thus in the material flow of the process. It is advisable to use temperature-dependent
parameters and to investigate in detail the influence of radiation in the entire
process.

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.

text: "AbstractWith an innovative optical characterization
method, using high-temperature digital image correlation in combination with thermal
imaging, the local change in strain and change in temperature could be determined
during thermo-mechanical treatment of flat steel specimens. 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

text: In biomedical engineering, laser powder bed fusion is an advanced manufacturing
technology, which enables, for example, the production of patient-customized implants
with complex geometries. 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.
