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.</jats:p>"}],"type":"journal_article","publication":"steel research international","doi":"10.1002/srin.202300530","title":"Influences of Weld Nugget Shape and Material Gradient on the Shear Strength of Resistance Spot‐Welded Joints","author":[{"first_name":"Lilia","last_name":"Schuster","full_name":"Schuster, Lilia"},{"first_name":"Viktoria","id":"5974","full_name":"Olfert, Viktoria","last_name":"Olfert"},{"first_name":"Oleksii","last_name":"Sherepenko","full_name":"Sherepenko, Oleksii"},{"first_name":"Clemens","full_name":"Fehrenbach, Clemens","last_name":"Fehrenbach"},{"full_name":"Song, Shiyuan","last_name":"Song","first_name":"Shiyuan"},{"first_name":"David","full_name":"Hein, David","id":"7728","last_name":"Hein"},{"first_name":"Gerson","orcid":"0000-0002-2763-1246","last_name":"Meschut","full_name":"Meschut, Gerson","id":"32056"},{"last_name":"Biro","full_name":"Biro, Elliot","first_name":"Elliot"},{"last_name":"Münstermann","full_name":"Münstermann, Sebastian","first_name":"Sebastian"}],"date_created":"2024-01-22T09:17:07Z","date_updated":"2024-03-18T12:49:31Z","publisher":"Wiley","citation":{"ama":"Schuster L, Olfert V, Sherepenko O, et al.

Ein wesentliches Kriterium bei der Auslegung von Verbindungen im Landmaschinenbau ist die Ermüdungsfestigkeit aufgrund der langen Nutzungsphase der Produkte und der in der Landtechnik vorherrschenden Belastungscharakteristika. Geklebte Verbindungen weisen ein hervorragendes Verhalten bei zyklischer Belastung auf. Die steigenden Anforderungen im Hinblick auf Ressourceneffizienz und Leichtbau führen zu einem Umdenken, da durch den vermehrten Einsatz höherfester Stahlwerkstoffe in Kombination mit der Klebtechnik dieses als umsetzbar erscheint. Ziel ist die Entwicklung einer Methode zur Auslegung geklebter Verbindungen in Konstruktionen mit höherfesten Stahlwerkstoffen in Anlehnung an die FKM‐Richtlinie. Die betriebsrelevanten Beanspruchungen der Landtechnik werden analysiert und an speziellen Probekörpern untersucht. Dabei werden sowohl die mechanischen, thermischen und medialen Einflussfaktoren als auch der Einfluss der Klebfugengeometrie und von Betriebslastenkollektiven untersucht. Die Erkenntnisse werden in einer KMU‐relevanten Vorgehensweise zur Ermittlung von Abminderungsfaktoren zusammengefasst, wodurch die Auslegung der Bauteilfestigkeit sowohl statisch als auch dynamisch möglich ist.</jats:p>"}],"volume":92,"author":[{"last_name":"Göddecke","id":"59070","full_name":"Göddecke, Johannes","first_name":"Johannes"},{"full_name":"Göhrs, Tim","last_name":"Göhrs","first_name":"Tim"},{"full_name":"Meschut, Gerson","id":"32056","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson"},{"full_name":"Große Gehling, Manfred","last_name":"Große Gehling","first_name":"Manfred"}],"date_updated":"2024-03-19T06:06:45Z","doi":"10.1002/stab.202300031","publication_identifier":{"issn":["0038-9145","1437-1049"]},"publication_status":"published","page":"508-519","intvolume":"        92","citation":{"chicago":"Göddecke, Johannes, Tim Göhrs, Gerson Meschut, and Manfred Große Gehling. “Auslegungsmethode zum Kleben höchstfester Stahlwerkstoffe im Landmaschinenbau.” <i>Stahlbau</i> 92, no. 8 (2023): 508–19. <a href=\"https://doi.org/10.1002/stab.202300031\">https://doi.org/10.1002/stab.202300031</a>.","ieee":"J.

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-<jats:italic>in situ</jats:italic> 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 <jats:italic>µ</jats:italic>m) 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-<jats:italic>in situ</jats:italic> 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 (E<jats:sub>corr</jats:sub>) of − 0.475 V referred to the standard hydrogen electrode (SHE) and a corrosion exchange current density (i<jats:sub>corr</jats:sub>) of 0.0848 A/m<jats:sup>2</jats:sup>. Furthermore, quasi-<jats:italic>in situ</jats:italic> 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.

Moreover, when different materials are to be joined, the parameter values need to be tailored to the specifics of the respective material. To this end, in this paper, three approaches to tailor the parameter values to optimize the quality of the connection are compared: a heuristic by Potente, statistical experimental design, and Bayesian optimization. With the suitability for practice in mind, a series of experiments are carried out with these approaches, and their capabilities of proposing well-performing parameter values are investigated. As a result, Bayesian optimization is found to yield peak performance, but the costs for optimization are substantial. In contrast, the Potente heuristic does not require any experimentation and recommends parameter values with competitive quality.</jats:p>","lang":"eng"}],"status":"public","date_updated":"2022-08-24T12:52:06Z","publisher":"Springer Science and Business Media LLC","author":[{"full_name":"Gevers, Karina","id":"83151","last_name":"Gevers","first_name":"Karina"},{"first_name":"Alexander","last_name":"Tornede","full_name":"Tornede, Alexander","id":"38209"},{"first_name":"Marcel Dominik","orcid":" https://orcid.org/0000-0001-9782-6818","last_name":"Wever","id":"33176","full_name":"Wever, Marcel Dominik"},{"full_name":"Schöppner, Volker","id":"20530","last_name":"Schöppner","first_name":"Volker"},{"first_name":"Eyke","last_name":"Hüllermeier","id":"48129","full_name":"Hüllermeier, Eyke"}],"date_created":"2022-08-24T12:51:07Z","title":"A comparison of heuristic, statistical, and machine learning methods for heated tool butt welding of two different materials","doi":"10.1007/s40194-022-01339-9","publication_identifier":{"issn":["0043-2288","1878-6669"]},"publication_status":"published","year":"2022","citation":{"apa":"Gevers, K., Tornede, A., Wever, M.

Clinch connections are applicable to difficult-to-join hybrid material combinations, such as steel and aluminum. Therefore, this technology is interesting for the application of AISI 304 components, as this material is widely used as a highly formable sheet material. A characteristic feature of AISI 304 is its metastability, i.e., the face-centered cubic (fcc) γ-austenite can transform into a significantly stronger body-centered cubic (bcc) α’-martensite under plastic deformation. This work investigates the effect of heat treatment—a process that involves the formation of an oxidation layer on the sheet surface—on the forming process during joining and the resulting mechanical properties of clinch joints made from AISI 304. For this purpose, different joints made from non-heat treated and heat-treated sheets were examined using classical metallography and advanced SEM techniques, accompanied by further investigations, such as hardness and feritscope measurements. The shear tensile strength was determined, and the fracture behavior of the samples was investigated. Clear influences of heat-treatment-induced surface roughness on the joint geometry and strength were observed."}],"publication":"Metals","keyword":["General Materials Science","Metals and Alloys"],"language":[{"iso":"eng"}],"year":"2022","issue":"9","title":"The Influence of Heat Treatment on the Microstructure, Surface Roughness and Shear Tensile Strength of AISI 304 Clinch Joints","publisher":"MDPI AG","date_created":"2022-12-06T19:25:49Z"},{"publisher":"MDPI AG","date_created":"2022-12-06T19:20:46Z","title":"Long-Term Behavior of Clinched Electrical Contacts","issue":"10","year":"2022","keyword":["General Materials Science","Metals and Alloys"],"language":[{"iso":"eng"}],"publication":"Metals","abstract":[{"text":"Joining by forming operations presents powerful and complex joining techniques. Clinching is a well-known joining process for use in sheet metalworking. Currently, clinched joints are focusing on mechanically enhanced connections. Additionally, the demand for integrating electrical requirements to transmit electrical currents will be increased in the future. This integration is particularly important, for instance, in the e-mobility sector. It enables connecting battery cells with electrical joints of aluminum and copper. Systematic use of the process-specific advantages of this joining method opens up the possibility to find and create electrically optimized connections. The optimization for the transmission of electrical currents will be demonstrated for clinched joints by adapting the tool geometry and the clinched joint design. Based on a comparison of the electrical joint resistance, the limit use temperature is defined for the joining materials used based on the microstructural condition and the aging condition due to artificial aging. As a result of the investigations carried out, reliable current transmission at a constant conductor temperature of up to 120 °C can be achieved for clinched copper–copper joints. In the case of pure aluminum joints and mixed joints of aluminum and copper, long-term stable current transmission can be ensured up to a conductor temperature of 100 °C.","lang":"eng"}],"oa":"1","date_updated":"2023-01-02T11:06:35Z","volume":12,"author":[{"first_name":"Jan","last_name":"Kalich","full_name":"Kalich, Jan"},{"first_name":"Marcus","last_name":"Matzke","full_name":"Matzke, Marcus"},{"first_name":"Wolfgang","full_name":"Pfeiffer, Wolfgang","last_name":"Pfeiffer"},{"first_name":"Stephan","full_name":"Schlegel, Stephan","last_name":"Schlegel"},{"first_name":"Ludwig","last_name":"Kornhuber","full_name":"Kornhuber, Ludwig"},{"last_name":"Füssel","full_name":"Füssel, Uwe","first_name":"Uwe"}],"doi":"10.3390/met12101651","main_file_link":[{"url":"https://www.mdpi.com/2075-4701/12/10/1651","open_access":"1"}],"publication_identifier":{"issn":["2075-4701"]},"publication_status":"published","intvolume":"        12","citation":{"apa":"Kalich, J., Matzke, M., Pfeiffer, W., Schlegel, S., Kornhuber, L., &#38; Füssel, U.

In this study, the interactions of different welding current levels and weld times on the tendency for LME cracking in third-generation AHSSs were investigated. LME manifested itself as high-penetration cracks around the circumference of the spot welds for welding currents closely below the expulsion limit. At the same time, the observed tendency for LME cracking showed no direct correlation with the overall heat input of the investigated welding processes. To identify a reliable indicator of the tendency for LME cracking, the local strain rate at the origin of the observed cracks was analyzed over the course of the welding process via finite element simulation. While the local strain rate showed a good correlation with the process-specific LME cracking tendency, it was difficult to interpret due to its discontinuous course. Therefore, based on the experimental measurement of electrode displacement during welding, electrode indentation velocity was proposed as a descriptive indicator for quantifying cracking tendency.</jats:p>"}],"publication":"Welding Journal","keyword":["Metals and Alloys","Mechanical Engineering","Mechanics of Materials"],"language":[{"iso":"eng"}]},{"date_updated":"2023-01-27T16:35:48Z","publisher":"Royal Society of Chemistry (RSC)","volume":58,"author":[{"last_name":"Kossmann","full_name":"Kossmann, Janina","first_name":"Janina"},{"full_name":"Sánchez-Manjavacas, Maria Luz Ortiz","last_name":"Sánchez-Manjavacas","first_name":"Maria Luz Ortiz"},{"first_name":"Jessica","last_name":"Brandt","full_name":"Brandt, Jessica"},{"last_name":"Heil","full_name":"Heil, Tobias","first_name":"Tobias"},{"first_name":"Nieves","full_name":"Lopez Salas, Nieves","id":"98120","orcid":"https://orcid.org/0000-0002-8438-9548","last_name":"Lopez Salas"},{"first_name":"Josep","last_name":"Albero","full_name":"Albero, Josep"}],"date_created":"2023-01-27T16:19:46Z","title":"Mn(<scp>ii</scp>) sub-nanometric site stabilization in noble, N-doped carbonaceous materials for electrochemical CO<sub>2</sub> reduction","doi":"10.1039/d2cc00585a","publication_identifier":{"issn":["1359-7345","1364-548X"]},"publication_status":"published","issue":"31","year":"2022","page":"4841-4844","intvolume":"        58","citation":{"apa":"Kossmann, J., Sánchez-Manjavacas, M.

Therefore, this paper includes an analysis of boundary conditions for the spatial discretization and mesh modeling techniques, the material modeling, the contact and friction modeling, and the thermal boundary conditions for the finite element (FE) modeling of this joining process. For these investigations, two FE models corresponding to the two process steps were set up and compared with the two related processes of friction stir welding and friction drilling. Regarding the spatial discretization, the Lagrangian approach is not sufficient to represent the deformation that occurs. The Johnson-Cook model is well suited as a material model. The modeling of the contact detection and friction are important research subjects. Coulomb’s law of friction is not adequate to account for the complex friction phenomena of the adaptive joining process. The thermal boundary conditions play a decisive role in heat generation and thus in the material flow of the process.

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.

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.</jats:p>","lang":"eng"}],"date_created":"2022-01-10T08:25:58Z","publisher":"MDPI AG","title":"Low Cycle Fatigue Performance of Additively Processed and Heat-Treated Ti-6Al-7Nb Alloy for Biomedical Applications","issue":"1","quality_controlled":"1","year":"2022"}]
