AB - (1) This work answers the question of whether and to what extent there is a significant difference in mechanical properties when different additive manufacturing processes are applied to the material 1.2709. 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.

AB - Many applications are driven by Machine Learning (ML) today. While complex ML models lead to an accurate prediction, their inner decision-making is obfuscated. However, especially for high-stakes decisions, interpretability and explainability of the model are necessary. Therefore, we develop a holistic interpretability and explainability framework (HIEF) to objectively describe and evaluate an intelligent system’s explainable AI (XAI) capacities. This guides data scientists to create more transparent models. To evaluate our framework, we analyse 50 real estate appraisal papers to ensure the robustness of HIEF. Additionally, we identify six typical types of intelligent systems, so-called archetypes, which range from explanatory to predictive, and demonstrate how researchers can use the framework to identify blind-spot topics in their domain. Finally, regarding comprehensiveness, we used a random sample of six intelligent systems and conducted an applicability check to provide external validity.

AB - Aufgrund der Leichtbauweise von Fahrzeugkarosserien werden konventionelle Stahlgüten durch ultrahöchstfeste Stahlwerkstoffe ersetzt. Die hohe Festigkeit dieser Werkstoffe stellt eine Herausforderung für das mechanische Fügen dar. Weil diese Stahlwerkstoffe zunehmend in erhöhter Dicke eingesetzt werden, wird die Leistungsfähigkeit konventioneller Halbhohlstanzniete überschritten. Im Rahmen des Forschungsvorhabens wurde ein Stanzniet erarbeitet, welcher eine Erweiterung des Einsatzbereichs des Halbhohlstanznietens auf stempelseitige Fügeteile aus höchstfesten und ultrahöchstfesten Stahlwerkstoffen bei großer Materialdicke ermöglicht. Zunächst wurden Referenzverbindungen mit handelsüblichen Stanznieten erstellt und analysiert. Durch die simulationsgestützte Ermittlung der Spannungs- und Dehnungsverhältnisse im Stanzniet wurden Ansätze für die Modifizierung der Stanzniete erarbeitet. Ebenso wurde der Einfluss der einzelnen Geometrieparameter des Stanzniets auf die Verformung des Stanzniets und die Verbindungsausbildung untersucht. Parallel dazu, wurden die mechanischen Eigenschaften potenzieller Stanznietwerkstoffe charakterisiert und eine angepasste Wärmebehandlungsstrategie erarbeitet. Durch die Modifizierung der Werkstofflegierung und der Wärmebehandlung kann eine Erhöhung der Festigkeit des Stanznietwerkstoffs um ca. 20 % gegenüber der bisher üblichen Härteklasse H6 erreicht werden. Daher kann eine Stanznietgeometrie mit einem bisher üblichen Nenndurchmesser von 5,5 mm verwendet werden. Die neuen Stanzniete wurden experimentell in einem zweistufigen Kaltumformprozess hergestellt. Abschließend wurde die erarbeitete Lösung basierend auf experimentellen Versuchen analysiert.

AB - Abstract
This paper investigates the price impact of the fuel discount in Germany, which was introduced between June and August 2022 to partially compensate increased energy costs. Using the augmented synthetic control method (ASCM) to construct the counterfactual, we provide quantitative evidence to the heated debate concerning the impact of this policy tool and find the fuel discount to have decreased consumer prices of petrol (diesel) by at least 0.30 euro per litre (0.10 euro per litre) on average. The results are robust to various sensitivity checks. Thus, oil companies and petrol stations decreased prices for consumers and passed on about 85 % (65 %) of the discount in case of petrol (diesel). Moreover, we do not find signs of excessive price increases in anticipation of the fuel discount.

AB - The current investigation shows the feasibility of 316L steel powder production via three different argon gas atomisation routes (closed coupled atomisation, free fall atomisation with and without hot gas), along with subsequent sample production by laser powder bed fusion (PBF-LB). Here, a mixture of pure Fe and atomised 316L steel powder is used for PBF-LB to induce a chemical composition gradient in the microstructure. Optical microscopy and μ-CT investigations proved that the samples processed by PBF-LB exhibit very little porosity. Combined EBSD-EDS measurements show the chemical composition gradient leading to the formation of a local fcc-structure. Upon heat treatment (1100 °C, 14 h), the chemical composition is homogeneous throughout the microstructure. A moderate decrease (1060 to 985 MPa) in the sample’s ultimate tensile strength (UTS) is observed after heat treatment. However, the total elongation of the as-built and heat-treated samples remains the same (≈22%). Similarly, a slight decrease in the hardness from 341 to 307 HV1 is observed upon heat treatment.

AB - This paper reveals the 3D character of the intermetallic layer at the aluminum–steel interface which pops
up above the original sample surface during annealing. Popping out of the intermetallics was proven using
atomic force microscopy. The phase expands out of the plane due to the exothermic formation of the Al5Fe2
phase and the feasibility of surface diffusion. Milling by a focused ion beam enabled the comparison of the
chemical composition of the surface layer with the bulk interface, showing no difference. The growth direction
is both towards aluminum and steel — the main diffusion flux is from aluminum towards steel, and the new
intermetallic phase emerges at the steel side. The shortage of Al atoms causes a shift of the intermetallic as a
whole towards aluminum.

AB - AbstractGraffiti is an urban phenomenon that is increasingly attracting the interest of the sciences. To the best of our knowledge, no suitable data corpora are available for systematic research until now. The Information System Graffiti in Germany project (Ingrid) closes this gap by dealing with graffiti image collections that have been made available to the project for public use. Within Ingrid, the graffiti images are collected, digitized and annotated. With this work, we aim to support the rapid access to a comprehensive data source on Ingrid targeted especially by researchers. In particular, we present IngridKG, an RDF knowledge graph of annotated graffiti, abides by the Linked Data and FAIR principles. We weekly update IngridKG by augmenting the new annotated graffiti to our knowledge graph. Our generation pipeline applies RDF data conversion, link discovery and data fusion approaches to the original data. The current version of IngridKG contains 460,640,154 triples and is linked to 3 other knowledge graphs by over 200,000 links. In our use case studies, we demonstrate the usefulness of our knowledge graph for different applications.

AB - We present a novel method for high-order phase reduction in networks of
weakly coupled oscillators and, more generally, perturbations of reducible
normally hyperbolic (quasi-)periodic tori. Our method works by computing an
asymptotic expansion for an embedding of the perturbed invariant torus, as well
as for the reduced phase dynamics in local coordinates. Both can be determined
to arbitrary degrees of accuracy, and we show that the phase dynamics may
directly be obtained in normal form. We apply the method to predict remote
synchronisation in a chain of coupled Stuart-Landau oscillators.

AB - In this work, we discuss the possibility of improving charge neutralization in near ambient pressure X-ray photoelectron spectroscopy by co-irradiating the sample with He I photons of 21.2 eV. This UV-enhanced neutralization of charges is a variation of the so-called environmental charge compensation, which uses the electrons produced by the photoionization of the ambient gas to neutralize the positive charges built at the sample surface. Adding an additional ionization source generates more charges at the sample but also larger amounts of electrons available for neutralization. The final surface charge equilibrium depends on different aspects of the experiment, such as the sample composition and geometry, the total ionization cross sections of the gas compared to the surface materials, the gas used, the luminosity and spot size of the sources used for photoionization, and the energy of the electrons present in the gas phase. Here we illustrate the efficiency of the UV-enhanced neutralization using three different dielectric samples with different geometries (a porous SiO2 monolith with an irregular surface, a flat mica sample, and a thin SiO2 film deposited onto a Si substrate), different X-ray spot sizes, and two different gases (N2 and Ar). The effect of biasing on the efficiency of the sample surface to attract electrons produced in the gas phase is also discussed.
