These, however, are unable to detect phenomena immediately during the joining process. For instance, elastic deformations reverse and cracks close after unloading. In situ methods such as the force-displacement evaluation are used to investigate a clinching process, though deviations in the clinch point geometry cannot be derived with this method. To overcome these limitations, the clinching process can be investigated using in situ computed tomography (in situ CT). When investigating the clinching of aluminum parts in in situ CT, the sheet-sheet interface is hardly visible. Earlier investigations showed that radiopaque materials can be applied between the joining parts to enhance the detectability of the sheet-sheet interface. However, the layers cause strong artefacts, break during the clinching process or change the clinch joint’s properties significantly. In this paper, a minimally invasive method to enhance the interface detectability is presented. First, the aluminum oxide layer is removed by etching. Second, the specimen is electroplated with copper or gold, respectively. In some cases, a mask is applied to create a cross-shaped plating pattern. Then, the plated specimen is clinched with a non-plated counterpart and the interface detectability of the clinch points is assessed in CT scans. It is shown that a copper plating of 2.6–4 μm can visualize some parts of the interface, while 7–9 μm is suitable to enhance the detectability of the sheet-sheet interface almost continuously." article_number: '131' article_type: original author: - first_name: Daniel full_name: Köhler, Daniel id: '83408' last_name: Köhler - first_name: Alrik full_name: Dargel, Alrik id: '114764' last_name: Dargel - first_name: Juliane full_name: Troschitz, Juliane last_name: Troschitz - first_name: Maik full_name: Gude, Maik last_name: Gude - first_name: Robert full_name: Kupfer, Robert last_name: Kupfer citation: ama: Köhler D, Dargel A, Troschitz J, Gude M, Kupfer R.

Recent research indicates that galvanic corrosion can actually enhance the fatigue life of clinched joints. It is then of significant interest to investigate the effects of another corrosion phenomenon, pitting corrosion, on the fatigue behavior of clinched joints. Pitting corrosion occurs in passive metals and can lead to stress concentrations. In the present study, the effects of pitting corrosion are investigated by using Lemaitre’s two-scale fatigue model with a 2D geometry of clinched joints. A slip condition is applied as a boundary condition to simplify the clinched joint model and reduce the computational cost of solving the contact mechanics problem. Additionally, a method to determine the damage strength and the damage exponent used in the two-scale damage model is introduced. Numerical simulations reveal that pitting corrosion reduces the fatigue life of clinched joints, particularly when it occurs on the internal surface in the neck area." author: - first_name: Chin full_name: Chen, Chin id: '114741' last_name: Chen - first_name: Sven full_name: Harzheim, Sven last_name: Harzheim - first_name: Martin full_name: Hofmann, Martin last_name: Hofmann - first_name: Thomas full_name: Wallmersperger, Thomas last_name: Wallmersperger citation: ama: Chen C, Harzheim S, Hofmann M, Wallmersperger T.

Several diagnostics were employed to characterize the spray and nanoparticles. \r\nIncreasing DG flow (6 - 12 slm) results in smaller droplet sizes (DS), cooler flame temperatures, shorter high-temperature droplet/particle residence times, and smaller agglomerates in the size range of 5 - 12 nm with narrower primary particle size distribution, corresponding to higher mass fractal dimensions, as supported by TEM and SMPS analysis, resulting in more compact agglomerates. BET and TEM confirmed decreasing primary particle sizes with increasing DG flow. Raman and XRD analyses predominantly identified maghemite, which shows a bimodal distribution of crystallite sizes, while SS1 samples have a greater proportion of larger crystallites.\r\nThe self-preserving size distributions of agglomerates with a geometric standard deviation of 1.5 are reached faster with increasing DG flow. The barrier effect of DG observed in SS1 leads to slower droplet combustion kinetics, higher temperatures, and delayed precursor release, which, along with downstream flow recirculation, result in significantly higher agglomeration rates outside the visible flame. SS2 demonstrates improved atomization, more stable flames, and finer, uniform nanoparticles with less carbonaceous residues (CR). Conversely, SS1 showed broader DS distributions and higher CR levels on the γ-Fe2O3 surface, especially at higher DG flow.\r\nThis work highlights the essential role of DG flow and nozzle geometry in controlling droplet evaporation, flame stability, and nanoparticle growth, offering insights for optimizing SFS and validating numerical models.\r\n" article_number: '121992' article_type: original author: - first_name: Orlando full_name: Massopo, Orlando last_name: Massopo - first_name: Ricardo full_name: Tischendorf, Ricardo last_name: Tischendorf - first_name: Munko full_name: Gonchikzhapov, Munko last_name: Gonchikzhapov - first_name: Tina full_name: Kasper, Tina last_name: Kasper - first_name: Peter full_name: Augustin, Peter last_name: Augustin - first_name: Burak full_name: Özer, Burak last_name: Özer - first_name: Manuel full_name: Reddemann, Manuel last_name: Reddemann - first_name: Reinhold full_name: Kneer, Reinhold last_name: Kneer - first_name: Mohammed-Ali full_name: Sheikh, Mohammed-Ali last_name: Sheikh - first_name: Aydan Akyildiz full_name: Mert, Aydan Akyildiz last_name: Mert - first_name: Hartmut full_name: Wiggers, Hartmut last_name: Wiggers - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim last_name: Schmid citation: ama: Massopo O, Tischendorf R, Gonchikzhapov M, et al.

Chromium thin films were deposited by electron beam evaporation on (001)-oriented bulk TiO\r\n 2\r\n substrates and subsequently diffused into the lattice in a tube furnace under a nitrogen atmosphere at 900 °C. The introduction of chromium significantly enhanced the third harmonic generation (THG) of a 1560 nm laser, with an amplification factor of up to 8.3, indicative of an enhanced third-order nonlinear susceptibility,\r\n \ χ\r\n (3)\r\n \ . Moreover, the application of an external voltage induced a pronounced EFISH signal in the chromium-doped samples, further confirming the enhanced nonlinear response. These results demonstrate that defect engineering via chromium doping in rutile TiO\r\n 2\r\n \ offers a promising pathway for the development of high-performance nonlinear optical devices.\r\n " article_number: '54320' author: - first_name: Marius full_name: Brinkmann, Marius last_name: Brinkmann - first_name: Falco full_name: Meier, Falco last_name: Meier - first_name: Vladimir full_name: Spedt, Vladimir last_name: Spedt - first_name: Cedrik full_name: Meier, Cedrik id: '20798' last_name: Meier orcid: https://orcid.org/0000-0002-3787-3572 citation: ama: Brinkmann M, Meier F, Spedt V, Meier C.
