text: "One of the major topics in the modern automotive industry is reducing emissions
and increasing the mileage\r\nrange. To tackle this challenge, on the one hand,
modifying the powertrain system is a possibility, and on the\r\nother hand, lightweight
design offers various possibilities. Multi-Material Design (MMD) involves designing
car\r\nbodies that combine different materials that require joining. Given the
variety of materials, mechanical joining\r\nprocesses are preferred. Especially
the current development of the Giga/Mega-casting process concerning\r\naluminium
casting and the subsequent mechanical joining illustrates the challenges of this
material group. In car\r\nproduction, aluminium castings are mainly made from
aluminium-silicon (AlSi) alloys. Ultimately, the alloy\r\nsystem's insufficient
ductility leads to crack initiation during mechanical joining. Cast parts are
therefore often\r\nused in areas of the car body that are exposed to high-pressure
loads. For example, self-piercing riveting (SPR) is\r\nused due to its high load-bearing
capacity. In this study, improved joinability is demonstrated by influencing the\r\nmicrostructure
through tailored solidification rates and a developed heat-treatment chain strategy
adapted for\r\nhypoeutectic AlSi systems. Data on microstructure, mechanical,
and joining properties are used to develop a\r\nsolidification-joining correlation
for the SPR process across a range of Si contents and solidification rates. The\r\npurpose
is to develop the ability to produce suitable aluminium castings with sufficient
joinability, thereby\r\nimproving versatility."

text: Lightweight design is a driving concept in modern automotive engineering to
minimize resource consumption over a vehicle's lifecycle through multi-material
design, which relies on the use of joining techniques in car body fabrication.
Multi-material design and the increasing trend towards producing large structural
components using the megacasting process pose considerable challenges, particularly
in the mechanical joining of aluminium-silicon (AlSi) castings. These castings
typically exhibit low ductility and are prone to cracking when mechanically joined.
Based on the excellent castability of hypoeutectic AlSi alloys, these are applied
in sand casting and die casting as well as in megacasting. With a silicon content
between 7 wt% and 12 wt%, these AlSi-alloys have a plate-like silicon phase that
initiates cracks during mechanical joining. To enhance the joinability of castings,
the research hypothesis is that improved solidification conditions enable a significant
modification in the microstructure and therefore, increase the mechanical properties.
During the manufacture of the castings using the sand casting process, the solidification
conditions within the structural elements are varied to modify the microstructure
to obtain castings with graded microstructure. The castings are evaluated using
mechanical, microstructural and joining testing methods and finally, a microstructure-joinability
correlation is established.

text: "One of the most important strategies for reducing CO2 emissions in the mobility
sector is lightweight construction. In particular, the car body offers several
opportunities for weight reduction. Multi-material designs are increasingly being
applied to select the most suitable material for the respective load and ultimately
achieve synergy effects. For example, aluminium castings are used at the nodes
of a spaceframe body. Subsequently, these are joined with profiles to form the
bodyshell. To join different materials mechanical joining techniques, such as
semi-tubular self-piercing riveting, are deployed. According to the current state
of the art, cracks occur in the aluminium castings during the mechanical joining
process as a result of the high degree of deformation. Although the aluminium
casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent
castability. In particular, the ability to cast thin structural parts is enabled
by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis
study addresses the mechanical joining properties of the near eutectic aluminium
casting alloy AlSi12, depending on different microstructures. These are achieved
by annealing processes and modifying agents. Through an adapted heat treatment,
the previously lamellar morphology can be transformed into a globular morphology,
which leads to increased ductility and prevents the formation of cracks during
the self-piercing riveting (SPR). The joinability is investigated using different
die geometries, whereas the joint formation is analysed regarding crack initiation.
To evaluate the increased ductility, microstructural and mechanical tests are
performed and finally, a microstructure-joinability correlation is established."

text: Abstract. Lightweight design is one of the central topics of the automotive
industry since reducing mass can save emissions over the entire life cycle of
a component. Nowadays, vehicle structures usually consist of a multi-material
design, which poses the additional challenge of joining these different materials.
Mechanical joining is the most common way of joining different types of materials.
Cast aluminium alloys of the AlSi system have a low ductility, which causes cracks
during the mechanical joining process in the joint. One research approach is to
achieve a fine microstructure by influencing the solidification rate since this
results in increased mechanical properties, specifically the elongation at fracture
and yield strength. A very fine microstructure can be achieved by utilizing Twin-roll
casting (TRC) which is a continuous casting process in which high solidification
rates of more than 100 K/s occur. In this study, the hypoeutectic cast aluminium
alloy AlSi9 is processed in the TRC process using copper rollers. The cast strips
are investigated regarding the microstructure-property correlation. A variation
of the roller materials and cooling conditions allows for an increase in the solidification
rate, whereby a defined, fine microstructure can be achieved, which enhances the
mechanical properties of the hypoeutectic aluminium casting alloys.

text: Abstract. Twin-Roll-Casting (TRC) is an energy- and cost-efficient
process to produce near-net-shape aluminum strips. Due to the high affinity of
molten aluminum to steel surfaces, those rollers show signs of wear throughout
the rolling campaign. This leads to the necessity of restoring the worn surfaces
to suitable parameters. The easiest way is to grind the surface till all superficial
defects are omitted. However, the thickness of the roller is not endless, therefore
the rollers must be replaced after a certain amount of surface reconditioning.
This ultimately leads to the non-usability of the roller. This research shows
a route to recondition the surface including the possibility of renewing worn-down
surfaces with an energy- and cost-efficient high-velocity oxygen fuel (HVOF) treatment
with subsequent grinding to the desired initial surface parameters.

text: "Aluminium-Silizium-Legierungen (AlSi) werden insbesondere bei der gießtechnischen\r\nHerstellung
von Leichtbaukomponenten für Fahrzeuge verwendet. Dieses Legierungssystem hat
hervorragende\r\nGießeigenschaften bei gleichzeitig akzeptablen mechanischen Eigenschaften.
Aufgrund des hohen\r\nSilizium-(Si)-Gehaltes, wodurch die Volumenkontraktion im
Phasenübergang von flüssig-fest nahezu\r\nunterbunden wird, neigen AlSi-Legierungen
dazu, feinere oder gröbere Si-Platten bei unterschiedlichen\r\nErstarrungsgeschwindigkeiten
zu bilden. Um die mechanischen Eigenschaften zu verbessern, werden\r\ndem Legierungssystem
in der Schmelzphase entweder Natrium (Na) oder Strontium (Sr) zugesetzt. Dies\r\nhat
zur Folge, dass sich eine fein lamellare Si-Morphologie bei der Erstarrung ausbildet;
dies kann ebenfalls\r\ndurch hohe Erstarrungsgeschwindigkeiten erreicht werden.
Ein nachfolgendes Lösungsglühen bewirkt\r\neine Sphäroidisierung der Si-Partikel
und dient der Steigerung der Duktilität. Aktuell fehlen fundierte\r\nErkenntnisse
zur Ausprägung der Si-Morphologie in Abhängigkeit der Erstarrungsgeschwindigkeit
oder\r\ninfolge einer Wärmebehandlung. Vor diesem Hintergrund werden in dieser
Studie verschiedene Behandlungsparameter\r\nin Bezug auf das Einformverhalten
der Si-Partikel mit einem bildauswertenden Verfahren\r\nevaluiert sowie unter

text: "Aluminium-silicon alloys (AlSi) are used in the casting of lightweight vehicle
components. This\r\nalloy system has excellent casting properties accompanied
by acceptable mechanical properties. Due to\r\nthe high silicon (Si) content,
which almost completely prevents volume contraction during the liquid-solid\r\nphase
transition, AlSi alloys tend to form finer or coarser Si plates at different solidification
rates. To\r\nimprove the mechanical properties, either sodium (Na) or strontium
(Sr) is added to the alloy system in\r\nthe melting phase. This results in the
formation of a fine lamellar Si morphology during solidification, which\r\ncan
also be achieved by high solidification rates. Subsequent solution annealing causes
spheroidisation\r\nof the Si particles and increases ductility. Currently, there
is a lack in scientific knowledge regarding the\r\nSi-morphology as a function
of solidification rate or as a result of heat treatment. Therefore, this study\r\nevaluates
various treatment parameters in relation to the shaping behaviour of Si particles
using an image\r\nanalysis method and correlates them with different chemical
compositions."

text: Titanium alloys are widely employed for biomedical implants due to
their high strength, biocompatibility, and corrosion resistance, yet their lack
of intrinsic antibacterial activity remains a major limitation. Incorporating
copper, an antibacterial and β-stabilising element, offers a promising strategy
to enhance implant performance. This study investigates Ti-6Al-7Nb modified with
1–9 wt.% Cu via in situ alloying during metal-based laser powder bed fusion (PBF-LB/M),
with the aim of assessing processability, microstructural evolution, and mechanical
properties. Highly dense samples (>99.9%) were produced across all Cu levels,
though chemical homogeneity strongly depended on processing parameters. Increasing
Cu content promoted β-phase stabilisation, Ti2Cu precipitation, and pronounced
grain refinement. Hardness and yield strength increased nearly linearly with Cu
addition, while ductility decreased sharply at ≥5 wt.% Cu due to intermetallic
formation, hot cracking, and brittle fracture. These results illustrate both the
opportunities and constraints of rapid alloy screening via PBF-LB/M. Overall,
moderate Cu additions of 1–3 wt.% provide the most favourable balance between
mechanical performance, manufacturability, and potential antibacterial functionality.
These findings provide a clear guideline for the design of Cu-functionalised titanium
implants and demonstrate the efficiency of in situ alloy screening for accelerated
materials development.

text: 'Die DFG-Projekte AddFeRo-PM (406108415) und AddFeRo-SR (465089065) untersuchten
die Potenziale des LB-PBF/M-Verfahrens zur Herstellung von Rotoren für unterschiedliche
elektrische Maschinen. Im interdisziplinären Ansatz wurden Materialentwicklung
und mechanische sowie elektromagnetische Optimierung verbunden. Im Projekt „AddFeRo-PM“
wurde der Rotor einer permanentmagneterregten Synchron- maschine (PMSM) untersucht.
FeSi erwies sich als geeignete Legierung, konnte aber wegen Spannungsrissen nur
bis zu 3 % Siliziumanteil (kurz: FeSi3) verarbeitet werden. Mechanische und elektromagnetische
Untersuchungen ermöglichten eine 3D-Optimierung der Rotorgeometrie und -struktur.
Der Demonstrator wurde additiv gefertigt und zeigt Leicht-baupotenziale sowie
reduzierte Drehmomentwelligkeit. Im Folgeprojekt „AddFeRo-SR“ kam eine Hochtemperatur-Bauraumheizung
(HTBH) zum Einsatz, die FeSi mit 6,5 % Siliziumanteil verarbeitbar machte, welches
bessere elektro- magnetische Eigenschaften bietet. Sie wurde bei einer Synchron-Reluktanzmaschine
(SynRM) getestet. Eine hybride Rotorfertigung erwies sich jedoch aufgrund von
HTBH-Einschränkungen als ungeeignet, weshalb eine einteilige Fertigung mit FeSi3
umgesetzt wurde. Experimente bestätigten vergleichbare Betriebsergebnisse zur
konventionellen Fertigung bei reduzierter Rotormasse. Zusätzlich wurde eine Methodik
entwickelt, um additive Verfahren als Ergänzung zur konventionellen Fertigung
zu integrieren. Beide Projekte zeigen das Potenzial additiver Fertigung für Leichtbau
und Wirkungsgradsteigerung im Elektromaschinenbau und bieten wertvolle Grundlagen
für industrielle Anwendungen.'

text: Abstract. The process of joining is used in numerous sectors of the
manufacturing industry, where constructions composed of individual components
or metal sheets are combined to form complex structures. A straightforward and
pervasive approach for joining materials of disparate natures and coated surfaces
is clinching. During the clinching process, plastic deformation, residual stresses
and damage are introduced into the joint. Due to time-varying service loads cracks
can initiate and propagate in the vicinity of the joint which limits the lifetime
of the clinched structure. In order to prevent those damage cases, it is crucial
to perform fracture mechanical evaluation of cracks in the joint region. Therefore,
this publication deals with the question of how plastic deformation, residual
stresses and damage need to be considered for the assessment of a crack. For this
purpose, simple substitute models are employed to illustrate the principles based
on the clinching application example.

text: Through tailoring the geometry and design of biomaterials, additive
manufacturing is revolutionizing the production of metallic patient-specific implants,
e.g., the Ti-6Al-7Nb alloy. Unfortunately, studies investigating this alloy showed
that additively produced samples exhibit anisotropic microstructures. This anisotropy
compromises the mechanical properties and complicates the loading state in the
implant. Moreover, the minimum requirements as specified per designated standards
such as ISO 5832-11 are not met. The remedy to this problem is performing a conventional
heat treatment. As this route requires energy, infrastructure, labor, and expertise,
which in turn mean time and money, many of the additive manufacturing benefits
are negated. Thus, the goal of this work was to achieve better isotropy by applying
only adapted additive manufacturing process parameters, specifically focusing
on the build orientations. In this work, samples orientated in 90°, 45°, and 0°
directions relative to the building platform were manufactured and tested. These
tests included mechanical (tensile and fatigue tests) as well as microstructural
analyses (SEM and EBSD). Subsequently, the results of these tests such as fractography
were correlated with the acquired mechanical properties. These showed that 90°-aligned
samples performed best under fatigue load and that all requirements specified
by the standard regarding monotonic load were met.

text: AbstractRolling processes of conventional
cast Al-Li alloys quickly reach their limits due to relatively poor material formability.
This can be overcome by using twin-roll casting to produce thin sheets. Further
thermomechanical treatment, including hot or cold rolling, and heat treatment
can adjust the mechanical properties of twin-roll cast Al-Li sheets. The whole
manufacturing chain requires detailed knowledge of the precipitation and dissolution
behavior during heating, soaking and cooling, to purposefully select any process
parameters. This study shows the process chain of a twin-roll cast Al–Cu–Li alloy
achieving a hardness of around 180 HV1 by adapting the heat treatment parameters
for homogenisation, hot rolling and age hardening. Both hardness and microstructure
evolution are visualised along the process chain.
