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.

text: "For a reliable, strength-compliant and fracture-resistant design of components
and technical structures and for the prevention of damage cases, both the criteria
of strength calculation and fracture mechanics are essential. In contrast to strength
calculation the fracture mechanics assumes the existence of cracks which might
further propagate due to the operational load. First, the present paper illustrates
the general procedure of a fracture mechanical evaluation of fatigue cracks in
order to assess practical damage cases. Fracture mechanical fundamentals which
are essential for the calculation of the stress intensity factors K\r\n
\ I and the experimental determination of
fracture mechanical material parameters (e.g. threshold ΔK\r\n
\ I,th against fatigue crack growth, crack
growth rate curve) are explained in detail. The subsequent fracture mechanical
evaluation on the basis of the local stress situation at the crack tip and the
fracture mechanical material data is executed for different materials and selected
crack problems. Hereby, the main focus is on the material HCT590X as it is the
essential material being investigated by TRR285."

text: The additive manufacturing (AM) of innovative lattice structures with
unique mechanical properties has received widespread attention due to the capability
of AM processes to fabricate freeform and intricate structures. The most common
way to characterize the additively manufactured lattice structures is via the
uniaxial compression test. However, although there are many applications for which
lattice structures are designed for bending (e.g., sandwich panels cores and some
medical implants), limited attention has been paid toward investigating the flexural
behavior of metallic AM lattice structures with tunable internal architectures.
The purpose of this study was to experimentally investigate the flexural behavior
of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio
(PR). Four configurations of lattice structure beams with positive, negative,
hybrid PR, and a novel hybrid PR with graded density were manufactured via the
laser powder bed fusion (LPBF) AM process and tested under four-point bending.
The manufacturability, microstructure, micro-hardness, and flexural properties
of the lattices were evaluated. During the bending tests, different failure mechanisms
were observed, which were highly dependent on the type of lattice geometry. The
best response in terms of absorbed energy was obtained for the functionally graded
hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed
a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the
positive PR (PPR) structure. This highlights the great potential for FGHPR lattices
to be used in protective devices, load-bearing medical implants, and energy-absorbing
applications.

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: Aluminium-steel clad composite was manufactured by twin-roll casting. An intermetallic
layer of Al5Fe2 and Al13Fe4 formed at the interface upon annealing above 500 °C.
During in-situ annealing in transmission electron microscope, the layer grew towards
the steel side of the interface in tongue-like protrusions. A study of furnace-annealed
samples revealed, that the bulk growth of the interface phase proceeds towards
the aluminium side. The growth towards steel is a surface effect that takes place
simultaneously with the bulk growth towards aluminium. At the beginning of the
intermetallic layer formation diffusion of Fe into aluminium prevails, afterwards
Al atoms diffuse throught the newly formed intermetallic layer towards steel and
the whole interface shifts towards aluminium. The kinetics of growth of the intermetallic
layer follows parabolic law in both cases, indicating that the growth is governed
by diffusion.

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.

text: "In order to reduce CO2 emissions in the transport sector, the approach of
load-adapted components is increasingly being pursued. For the design of such
components, it is crucial to determine their resulting microstructure and mechanical
properties. For this purpose, continuous cooling transformation diagrams and deformation
continuous cooling transformation diagrams are utilized, however, their curves
are strongly influenced by the chemical composition, the initial state and especially
the process parameters.\r\n\r\nIn this study, the influence of the process parameters
on the transformation kinetics is systematically investigated using an innovative
characterization method. The experimental setup allowed a near-process analysis
of the transformation kinetics, resulting microstructure and mechanical properties
for a specific process route with a reduced number of specimens. A systematic
investigation of the effects of different process parameters on the microstructural
and mechanical properties made it possible to reveal interactions and independencies
between the process parameters in order to design a partial heating or differential
cooling process. Furthermore, the implementation of two different cooling conditions,
representative of differential cooling in the die relief method with tool-contact
and non-contact areas, showed that the soaking duration has a significant influence
on the microstructure in the non-contact tool area."

text: In this study, the design, additive manufacturing and experimental
as well as simulation investigation of mechanical and thermal properties of cellular
solids are addressed. For this, two cellular solids having nested and non-nested
structures are designed and additively manufactured via laser powder bed fusion.
The primary objective is to design cellular solids which absorb a significant
amount of energy upon impact loading without transmitting a high amount of stress
into the cellular solids. Therefore, compression testing of the two cellular solids
is performed. The nested and non-nested cellular solids show similar energy absorption
properties; however, the nested cellular solid transmits a lower amount of stress
in the cellular structure compared to the non-nested cellular solid. The experimentally
measured strain (by DIC) in the interior region of the nested cellular solid is
lower despite a higher value of externally imposed compressive strain. The second
objective of this study is to determine the thermal insulation properties of cellular
solids. For measuring the thermal insulation properties, the samples are placed
on a hot plate; and the surface temperature distribution is measured by an infrared
camera. The thermal insulating performance of both cellular types is sufficient
for temperatures exceeding 100 °C. However, the thermal insulating performance
of a non-nested cellular solid is slightly better than that of the nested cellular
solid. Additional thermal simulations predict a relatively higher temperature
distribution on the cellular solid surfaces compared to experimental results.
The simulated residual stress shows a similar distribution for both types, but
the magnitude of residual stress is different for the cellular solids upon cooling
from different temperatures of the hot plate.

text: The additive manufacturing (AM) of innovative lattice structures with
unique mechanical properties has received widespread attention due to the capability
of AM processes to fabricate freeform and intricate structures. The most common
way to characterize the additively manufactured lattice structures is via the
uniaxial compression test. However, although there are many applications for which
lattice structures are designed for bending (e.g., sandwich panels cores and some
medical implants), limited attention has been paid toward investigating the flexural
behavior of metallic AM lattice structures with tunable internal architectures.
The purpose of this study was to experimentally investigate the flexural behavior
of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio
(PR). Four configurations of lattice structure beams with positive, negative,
hybrid PR, and a novel hybrid PR with graded density were manufactured via the
laser powder bed fusion (LPBF) AM process and tested under four-point bending.
The manufacturability, microstructure, micro-hardness, and flexural properties
of the lattices were evaluated. During the bending tests, different failure mechanisms
were observed, which were highly dependent on the type of lattice geometry. The
best response in terms of absorbed energy was obtained for the functionally graded
hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed
a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the
positive PR (PPR) structure. This highlights the great potential for FGHPR lattices
to be used in protective devices, load-bearing medical implants, and energy-absorbing
applications.

text: Titanium alloys, especially β alloys, are favorable as implant materials
due to their promising combination of low Young’s modulus, high strength, corrosion
resistance, and biocompatibility. In particular, the low Young’s moduli reduce
the risk of stress shielding and implant loosening. The processing of Ti-24Nb-4Zr-8Sn
through laser powder bed fusion is presented. The specimens were heat-treated,
and the microstructure was investigated using X-ray diffraction, scanning electron
microscopy, and transmission electron microscopy. The mechanical properties were
determined by hardness and tensile tests. The microstructures reveal a mainly
β microstructure with α″ formation for high cooling rates and α precipitates after
moderate cooling rates or aging. The as-built and α″ phase containing conditions
exhibit a hardness around 225 HV5, yield strengths (YS) from 340 to 490 MPa, ultimate
tensile strengths (UTS) around 706 MPa, fracture elongations around 20%, and Young’s
moduli about 50 GPa. The α precipitates containing conditions reveal a hardness
around 297 HV5, YS around 812 MPa, UTS from 871 to 931 MPa, fracture elongations
around 12%, and Young’s moduli about 75 GPa. Ti-24Nb-4Zr-8Sn exhibits, depending
on the heat treatment, promising properties regarding the material behavior and
the opportunity to tailor the mechanical performance as a low modulus, high strength
implant material.
