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. author: - first_name: Lilia full_name: Schuster, Lilia last_name: Schuster - first_name: Viktoria full_name: Olfert, Viktoria id: '5974' last_name: Olfert - first_name: Oleksii full_name: Sherepenko, Oleksii last_name: Sherepenko - first_name: Clemens full_name: Fehrenbach, Clemens last_name: Fehrenbach - first_name: Shiyuan full_name: Song, Shiyuan last_name: Song - first_name: David full_name: Hein, David id: '7728' last_name: Hein - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Elliot full_name: Biro, Elliot last_name: Biro - first_name: Sebastian full_name: Münstermann, Sebastian last_name: Münstermann citation: ama: Schuster L, Olfert V, Sherepenko O, et al.

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. article_number: '117' author: - first_name: Dennis full_name: Milaege, Dennis id: '35461' last_name: Milaege - first_name: Niklas full_name: Eschemann, Niklas last_name: Eschemann - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Milaege D, Eschemann N, Hoyer K-P, Schaper M.

HF significantly influences the performance of Li-ion batteries, for example by impacting the formation of the solid electrolyte interphase at the anode and by affecting transition metal dissolution at the cathode. Additionally, HF complicates studying fundamental interfacial electrochemistry of Li-ion battery electrolytes, such as direct anion reduction, because it is electrocatalytically relatively unstable, resulting in LiF passivation layers. Methods to selectively remove ppm levels of HF from LiPF6-containing carbonate-based electrolytes are limited. We introduce and benchmark a simple yet efficient electrochemical in situ method to selectively remove ppm amounts of HF from LiPF6-containing carbonate-based electrolytes. The basic idea is the application of a suitable potential to a high surface-area metallic electrode upon which only HF reacts (electrocatalytically) while all other electrolyte components are unaffected under the respective conditions. article_type: original author: - first_name: Xiaokun full_name: Ge, Xiaokun last_name: Ge - first_name: Marten full_name: Huck, Marten last_name: Huck - first_name: Andreas full_name: Kuhlmann, Andreas last_name: Kuhlmann - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger - first_name: Xiaodan full_name: Xu, Xiaodan last_name: Xu - first_name: Zhenyu full_name: Zhao, Zhenyu last_name: Zhao - first_name: Hans-Georg full_name: Steinrueck, Hans-Georg last_name: Steinrueck citation: ama: Ge X, Huck M, Kuhlmann A, et al.

Despite their reduced dimensionality, they can exhibit complex non-Ising polarization configurations and unexpected physical properties. Here, the impact of the three-dimensional (3D) curvature on the polarization profile of nominally uncharged 180° domain walls in LiNbO3 is studied using second-harmonic generation microscopy and 3D polarimetry analysis. Correlations between the domain-wall curvature and the variation of its internal polarization unfold in the form of modulations of the Néel-like character, which we attribute to the flexoelectric effect. While the Néel-like character originates mainly from the tilting of the domain wall, the internal polarization adjusts its orientation due to the synergetic upshot of dipolar and monopolar bound charges and their variation with the 3D curvature. Our results show that curved interfaces in solid crystals may offer a rich playground for tailoring nanoscale polar states. article_type: original author: - first_name: Ulises full_name: Acevedo-Salas, Ulises last_name: Acevedo-Salas - first_name: Boris full_name: Croes, Boris last_name: Croes - first_name: Yide full_name: Zhang, Yide last_name: Zhang - first_name: Olivier full_name: Cregut, Olivier last_name: Cregut - first_name: Kokou Dodzi full_name: Dorkenoo, Kokou Dodzi last_name: Dorkenoo - first_name: Benjamin full_name: Kirbus, Benjamin last_name: Kirbus - first_name: Ekta full_name: Singh, Ekta last_name: Singh - first_name: Henrik full_name: Beccard, Henrik last_name: Beccard - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng - first_name: Riccardo full_name: Hertel, Riccardo last_name: Hertel - first_name: Eugene A. full_name: Eliseev, Eugene A. last_name: Eliseev - first_name: Anna N. full_name: Morozovska, Anna N. last_name: Morozovska - first_name: Salia full_name: Cherifi-Hertel, Salia last_name: Cherifi-Hertel citation: ama: Acevedo-Salas U, Croes B, Zhang Y, et al.

The fabrication of low-loss optical waveguides, as well as high-grade periodically poled ferroelectric domain structures, requires a profound understanding of the material properties and crystal structure. In this regard, Raman spectroscopy offers the possibility to study and visualize domain structures, strain, defects, and the local stoichiometry, which are all factors impacting device performance. However, the accurate interpretation of Raman spectra and their changes with respect to extrinsic and intrinsic defects requires a thorough assignment of the Raman modes to their respective crystal features, which to date is only partly conducted based on phenomenological modelling. To address this issue, we calculated the phonon spectra of potassium titanyl phosphate and the related compounds rubidium titanyl phosphate (RbTiOPO4) and potassium titanyl arsenate (KTiOAsO4) based on density functional theory and compared them with experimental data. Overall, this allows us to assign various spectral features to eigenmodes of lattice substructures with improved detail compared to previous assignments. Nevertheless, the analysis also shows that not all features of the spectra can unambigiously be explained yet. A possible explanation might be that defects or long range fields not included in the modeling play a crucial rule for the resulting Raman spectrum. In conclusion, this work provides an improved foundation into the vibrational properties in the KTiOPO4 material family. article_number: '1423' author: - first_name: Sergej full_name: Neufeld, Sergej last_name: Neufeld - first_name: Uwe full_name: Gerstmann, Uwe id: '171' last_name: Gerstmann orcid: 0000-0002-4476-223X - first_name: Laura full_name: Padberg, Laura id: '40300' last_name: Padberg - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 - first_name: Gerhard full_name: Berth, Gerhard id: '53' last_name: Berth - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 citation: ama: Neufeld S, Gerstmann U, Padberg L, et al.

For this purpose, single crystals of these solid solutions were grown with Czochralski pulling along the c-axis. Elemental composition of Nb and Ta was investigated using XRF analysis, and small samples with homogeneous and well known composition were used for the DSC measurements. We observed that the ferroelectric Curie temperature decreases linearly with increasing Ta concentration in the LiNb1−x Tax O3 solid solution crystals. Furthermore, the ferroelectric transition width of a mixed crystal appears to be smaller, as compared to pure LiTaO3. article_type: original author: - first_name: Umar full_name: Bashir, Umar last_name: Bashir - first_name: Klaus full_name: Böttcher, Klaus last_name: Böttcher - first_name: Detlef full_name: Klimm, Detlef last_name: Klimm - first_name: Steffen full_name: Ganschow, Steffen last_name: Ganschow - first_name: Felix full_name: Bernhardt, Felix last_name: Bernhardt - first_name: Simone full_name: Sanna, Simone last_name: Sanna - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng - first_name: Matthias full_name: Bickermann, Matthias last_name: Bickermann citation: ama: 'Bashir U, Böttcher K, Klimm D, et al.

To mitigate the narrowing of coronary artery atherosclerosis (stenosis), the computational modelling of auxetic and non-auxetic stents was performed in this study to minimise or even avoid these deposition agents in the future. Computational modelling was performed in unrestricted (open) conditions and restricted (in an artery) conditions. Finally, stent designs were produced by additive manufacturing, and mechanical testing of the stents was undertaken. Auxetic stent 1 and auxetic stent 2 exhibit very little foreshortening and radial recoil in unrestricted deployment conditions compared to non-auxetic stent 3. However, stent 2 shows structural instability (strut failure) during unrestricted deployment conditions. For the restricted deployment condition, stent 1 shows a higher radial recoil compared to stent 3. In the tensile test simulations, short elongation for stent 1 due to strut failure is demonstrated, whereas no structural instability is noticed for stent 2 and stent 3 until 0.5 (mm/mm) strain. The as-built samples show a significant thickening of the struts of the stents resulting in short elongations during tensile testing compared to the simulations (stent 2 and stent 3). A modelling framework for the stent deployment system that enables the selection of appropriate stent designs before in vivo testing is required. This leads to the acceleration of the development process and a reduction in time, resulting in less material wastage. The modelling framework shall be useful for doctors designing patient-specific stents. article_number: '1592' author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Dennis full_name: Milaege, Dennis last_name: Milaege - first_name: Maxwell full_name: Hein, Maxwell id: '52771' last_name: Hein orcid: 0000-0002-3732-2236 - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'Pramanik S, Milaege D, Hein M, Hoyer K-P, Schaper M.

Knowledge on the thermal conductivity of paraffins is necessary for the design and optimization of heat storage systems. However, for most paraffins solely the thermal conductivity of the liquid state has been sufficiently investigated. For the solid state, precise thermal conductivity data are only known for a few paraffins, while only generalized values are available for the remainder, some of which contradict each other. In this study, a measurement setup based on the modified guarded hot plate method is developed. It is used to investigate the thermal conductivity of several paraffines in the solid state, including pure n-docosane and its compounds with different types and concentrations of graphite. For n-docosane in the solid state, the thermal conductivity is determined to be 0.49 W/(m K). A particle size of 200 μm with a spherical shape turns out to be optimal to increase the thermal conductivity. This allows the thermal conductivity of a compound with 10% graphite to increase by a factor of three compared to the pure paraffin. Furthermore, significant differences to thermal conductivity data from the literature are found. author: - first_name: Andreas full_name: Paul, Andreas id: '7828' last_name: Paul - first_name: Elmar full_name: Baumhögger, Elmar id: '15164' last_name: Baumhögger - first_name: Mats-Ole full_name: Dewerth, Mats-Ole id: '49826' last_name: Dewerth - first_name: Iman full_name: Hami Dindar, Iman id: '54836' last_name: Hami Dindar - first_name: Gerrit full_name: Sonnenrein, Gerrit last_name: Sonnenrein - first_name: Jadran full_name: Vrabec, Jadran last_name: Vrabec citation: ama: Paul A, Baumhögger E, Dewerth M-O, Hami Dindar I, Sonnenrein G, Vrabec J.

This is mainly related to the constantly emerging challenges, such as not only the development of high-strength concretes is progressing very fast but also the simulation of the flow behaviour is of high importance. The main problem, however, is that the rheological characterisation of fresh concrete is not possible via commercial rheometers. The so-called concrete rheometers provide valuable relative values for comparing different concretes, but they cannot measure absolute values. Therefore, we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement of fresh concrete with particles up to \r\n \r\n \ \r\n \r\n \r\n \ \r\n d\r\n \ \r\n \r\n \ max\r\n \r\n \ \r\n =\r\n \ 5.5\r\n \r\n mm\r\n \ \r\n {d}_{{\\rm{\\max }}}=5.5\\hspace{.5em}{\\rm{mm}}\r\n \r\n \ . The comparison of the ACCR with a commercial rheometer showed very good agreement for selected test materials (Newtonian fluid, shear thinning fluid, suspension, and yield stress fluid), so that self-compacting concrete was subsequently measured. Since these measurements showed a very high reproducibility, the rheological properties of the fresh concrete could be determined with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified Bingham (MB) models) were also tested for their applicability, with the Bingham and the modified Bingham model proving to be the best suitable ones." author: - first_name: Sebastian full_name: Josch, Sebastian id: '38243' last_name: Josch - first_name: Steffen full_name: Jesinghausen, Steffen id: '3959' last_name: Jesinghausen orcid: https://orcid.org/0000-0003-2611-5298 - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim id: '464' last_name: Schmid orcid: 000-0001-8590-1921 citation: ama: Josch S, Jesinghausen S, Schmid H-J.

Challenges, such as high volume expansion of the S-cathode upon discharge, low electronic conductivity of S as active material and herewith limited rate capability as well as the shuttling of polysulfides (PSs) as intermediates often impede the cycle stability and practical application of Na-S batteries. Sulfurized poly(acrylonitrile) (SPAN) inherently inhibits the shuttling of PSs and shows compatibility with carbonate-based electrolytes, however, its exact redox mechanism remained unclear to date. Herein, we implement a commercially available and simple electrolyte into the Na-SPAN cell chemistry and demonstrate its high rate and cycle stability. Through the application of in situ techniques utilizing electronic impedance spectroscopy (EIS) and X-ray absorption spectroscopy (XAS) at different depths of charge and discharge, an insight into SPAN’s redox chemistry is obtained. article_number: '010526' author: - first_name: Julian full_name: Kappler, Julian last_name: Kappler - first_name: Güldeniz full_name: Tonbul, Güldeniz id: '89054' last_name: Tonbul orcid: 0000-0002-0999-9995 - first_name: Roland full_name: Schoch, Roland id: '48467' last_name: Schoch orcid: 0000-0003-2061-7289 - first_name: Saravanakumar full_name: Murugan, Saravanakumar last_name: Murugan - first_name: Michał full_name: Nowakowski, Michał id: '78878' last_name: Nowakowski orcid: 0000-0002-3734-7011 - first_name: Pia Lena full_name: Lange, Pia Lena last_name: Lange - first_name: Sina Vanessa full_name: Klostermann, Sina Vanessa last_name: Klostermann - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 - first_name: Thomas full_name: Schleid, Thomas last_name: Schleid - first_name: Johannes full_name: Kästner, Johannes last_name: Kästner - first_name: Michael Rudolf full_name: Buchmeiser, Michael Rudolf last_name: Buchmeiser citation: ama: Kappler J, Tonbul G, Schoch R, et al.

Typically, bulky pulse compressors consisting of gratings or prisms are used\r\nto address this issue by precompensating the dispersion of the optical components. However, these devices are only able to compensate for a part of the dispersion (second-order dispersion). Here, we present a compact pulse-shaping device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral phase delay allowing for a full dispersion control. Furthermore, with specific phase encodings, this device can be used to temporally reshape the incident laser pulses into more complex pulse forms such as a double pulse. We verify the performance of our device by using an SHG-FROG measurement setup together with a retrieval algorithm to extract the dispersion that our device applies to an incident laser pulse." article_type: original author: - first_name: René full_name: Geromel, René last_name: Geromel - first_name: Philip full_name: Georgi, Philip last_name: Georgi - first_name: Maximilian full_name: Protte, Maximilian id: '46170' last_name: Protte - first_name: Shiwei full_name: Lei, Shiwei last_name: Lei - first_name: Tim full_name: Bartley, Tim id: '49683' last_name: Bartley - first_name: Lingling full_name: Huang, Lingling last_name: Huang - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 citation: ama: Geromel R, Georgi P, Protte M, et al.

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." author: - first_name: Sudipta full_name: Pramanik, Sudipta last_name: Pramanik - first_name: Jan Tobias full_name: Krüger, Jan Tobias id: '44307' last_name: Krüger orcid: 0000-0002-0827-9654 - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer citation: ama: Pramanik S, Krüger JT, Schaper M, Hoyer K-P.

The Laser-Powder-Bed-Fusion (L-PBF) and Laser-Metal-Deposition (LMD) processes are considered, as they differ fundamentally in the way a part is manufactured. (2) Known process parameters for low-porosity parts were used to fabricate tensile strength specimens. Half of the specimens were heat-treated, and all specimens were tested for mechanical properties in a quasi-static tensile test. In addition, the material hardness was determined. (3) It was found that, firstly, heat treatment resulted in a sharp increase in mechanical properties such as hardness, elastic modulus, yield strength and ultimate strength. In addition to the increase in these properties, the elongation at break also decreases significantly after heat treatment. The choice of process, on the other hand, does not give either process a clear advantage in terms of mechanical properties but shows that it is necessary to consider the essential mechanical properties for a desired application. article_number: '157' article_type: original author: - first_name: Stefan full_name: Gnaase, Stefan id: '25730' last_name: Gnaase - first_name: Dennis full_name: Niggemeyer, Dennis id: '77214' last_name: Niggemeyer - first_name: Dennis full_name: Lehnert, Dennis id: '90491' last_name: Lehnert - first_name: Christian full_name: Bödger, Christian id: '93904' last_name: Bödger - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Gnaase S, Niggemeyer D, Lehnert D, Bödger C, Tröster T.
