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: 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: The development of bioresorbable materials for temporary implantation
enables progress in medical technology. Iron (Fe)-based degradable materials are
biocompatible and exhibit good mechanical properties, but their degradation rate
is low. Aside from alloying with Manganese (Mn), the creation of phases with high
electrochemical potential such as silver (Ag) phases to cause the anodic dissolution
of FeMn is promising. However, to enable residue-free dissolution, the Ag needs
to be modified. This concern is addressed, as FeMn modified with a degradable
Ag-Calcium-Lanthanum (AgCaLa) alloy is investigated. The electrochemical properties
and the degradation behavior are determined via a static immersion test. The local
differences in electrochemical potential increase the degradation rate (low pH
values), and the formation of gaps around the Ag phases (neutral pH values) demonstrates
the benefit of the strategy. Nevertheless, the formation of corrosion-inhibiting
layers avoids an increased degradation rate under a neutral pH value. The complete
bioresorption of the material is possible since the phases of the degradable AgCaLa
alloy dissolve after the FeMn matrix. Cell viability tests reveal biocompatibility,
and the antibacterial activity of the degradation supernatant is observed. Thus,
FeMn modified with degradable AgCaLa phases is promising as a bioresorbable material
if corrosion-inhibiting layers can be diminished.

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: The development of bioresorbable materials for temporary implantation
enables progress in medical technology. Iron (Fe)-based degradable materials are
biocompatible and exhibit good mechanical properties, but their degradation rate
is low. Aside from alloying with Manganese (Mn), the creation of phases with high
electrochemical potential such as silver (Ag) phases to cause the anodic dissolution
of FeMn is promising. However, to enable residue-free dissolution, the Ag needs
to be modified. This concern is addressed, as FeMn modified with a degradable
Ag-Calcium-Lanthanum (AgCaLa) alloy is investigated. The electrochemical properties
and the degradation behavior are determined via a static immersion test. The local
differences in electrochemical potential increase the degradation rate (low pH
values), and the formation of gaps around the Ag phases (neutral pH values) demonstrates
the benefit of the strategy. Nevertheless, the formation of corrosion-inhibiting
layers avoids an increased degradation rate under a neutral pH value. The complete
bioresorption of the material is possible since the phases of the degradable AgCaLa
alloy dissolve after the FeMn matrix. Cell viability tests reveal biocompatibility,
and the antibacterial activity of the degradation supernatant is observed. Thus,
FeMn modified with degradable AgCaLa phases is promising as a bioresorbable material
if corrosion-inhibiting layers can be diminished.

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 development of bioresorbable materials for temporary implantation
enables progress in medical technology. Iron (Fe)-based degradable materials are
biocompatible and exhibit good mechanical properties, but their degradation rate
is low. Aside from alloying with Manganese (Mn), the creation of phases with high
electrochemical potential such as silver (Ag) phases to cause the anodic dissolution
of FeMn is promising. However, to enable residue-free dissolution, the Ag needs
to be modified. This concern is addressed, as FeMn modified with a degradable
Ag-Calcium-Lanthanum (AgCaLa) alloy is investigated. The electrochemical properties
and the degradation behavior are determined via a static immersion test. The local
differences in electrochemical potential increase the degradation rate (low pH
values), and the formation of gaps around the Ag phases (neutral pH values) demonstrates
the benefit of the strategy. Nevertheless, the formation of corrosion-inhibiting
layers avoids an increased degradation rate under a neutral pH value. The complete
bioresorption of the material is possible since the phases of the degradable AgCaLa
alloy dissolve after the FeMn matrix. Cell viability tests reveal biocompatibility,
and the antibacterial activity of the degradation supernatant is observed. Thus,
FeMn modified with degradable AgCaLa phases is promising as a bioresorbable material
if corrosion-inhibiting layers can be diminished.

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.

text: The quasi in-situ indentation behaviour of <110>||BD and <111>||BD-oriented
grains in a FeCo alloy is studied in this investigation. The effect of build height
on melt pool shape and melt pool size is also studied by finite element method
simulations. As the building height increases, the aspect ratio of the elliptical
melt pool increases. Correspondingly, the effect of the laser scan speed on the
melt pool shape and size is studied by the finite element method, because, as
the laser scan speed increases, the aspect ratio of the elliptical melt pool increases,
too. The microstructural characterisation of the indentation area before and after
indentation is performed by electron backscatter diffraction (EBSD). Based on
the EBSD data grain reference orientation deviation (GROD), calculations are performed
to describe the effect of indentations on the neighbouring grain orientations.
High GROD angles are detected in the neighbouring grain region adjoining the indented
grain. An in-depth slip trace analysis shows the activation of all three slip
systems ({110}<111>, {112}<111> and {123}<111>) which is also
confirmed by slip lines on the sample surface that are detected by laser scanning
confocal microscopy. A high concentration of geometrically necessary dislocations
(GNDs) are observed on the adjoining area to the indentation. Local surface topography
measurements by laser scanning confocal microscopy confirmed the formation of
pile-ups near the indentation.
