This new “TISTRAQ” process is composed of two steps. In terms of process technology, the first step is comparable to a direct press-hardening process already well known for steels. In this step, the Ti-6Al-4V sheet material is resistively heated to a temperature below β-transus Tβ and, after a very short holding time, simultaneously formed and quenched by use of water cooled tools. Thereby, the β phase undergoes a martensitic transformation. The second step is a subsequent short-time annealing, which leads to a hardening of the material. In this work, a new test rig using resistive heating technique was used in order to produce\r\ndifferent solution treated and tool quenched (STQ) and subsequently annealed (STA) states. In this paper, the effects of heating rate, solution treatment temperature and holding time on microstructure and mechanical properties are addressed. For the characterisation, tensile testing and scanning electron microscopy were used. By the systematic variation of applied processing parameters, dominating effects on microstructure and mechanical properties were evaluated. For example, the solution treatment temperature was found to have a significant effect on microstructural features and characteristic strength and strain values. The obtained results reveal a high potential for future technical applications.","lang":"eng"}],"user_id":"72351","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"_id":"49437","language":[{"iso":"eng"}],"keyword":["Ti-6Al-4V","thermomechanical processing","resistive heating","quench-forming","process parameter-microstructure-properties relationship"]},{"title":"The Influence of Ultrasonic Irradiation of a 316L Weld Pool Produced by DED on the Mechanical Properties of the Produced Component","publisher":"MDPI AG","date_created":"2024-11-28T08:45:06Z","year":"2024","quality_controlled":"1","issue":"11","ddc":["670"],"language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"<jats:p>Additive manufacturing of metallic components often results in the formation of columnar grain structures aligned along the build direction.

High-intensity ultrasound was applied during the direct energy deposition (DED) process to inhibit the formation of columnar grains. The investigation emphasized the importance of amplitude changes of the ultrasound wave as the system’s geometry continuously evolves with the addition of multiple layers and assessed how these changes influence the grain size and distribution.

Traditionally, joints are cylindrical and rotationally symmetric.

Single lap joint specimens were fabricated using the In-Mold assembly technique for joining steel sheets with GMT. Tensile shear tests were performed on different orientations of the joint geometry, and it was observed that changing the joint orientation influences the load-bearing capacity. The joints are constitutively modeled using beam elements and the influence of joint rotation on load distribution is examined through a static simulation study. </jats:p>"}],"status":"public","_id":"55638","project":[{"_id":"140","name":"TRR 285 – B01: TRR 285 - Subproject B01"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"department":[{"_id":"149"},{"_id":"321"},{"_id":"9"}],"user_id":"76837","language":[{"iso":"eng"}]},{"type":"dissertation","status":"public","abstract":[{"lang":"eng","text":"Die Auslegung von gefügten Bauteilen ermöglicht die Produktion von Strukturbauteilen, welche teils aus sehr vielen Einzelteilen bestehen und durch eine hohe Anzahl von Fügepunkten verbunden sind.

Um diese Bauteile stets nach der Spezifikation zu liefern, werden die Prozesse gewöhnlich über die gesamte Prozesskette überwacht und das Bauteil überdimensioniert. Treten unvorhersehbare Störungen in der Prozesskette auf, kann das Bauteil nicht mehr weiter produziert werden. Entweder muss die Störung im Prozess behoben werden, was nicht immer möglich ist und die schon teils produzierte Charge muss vernichtet werden, oder der Teil der Prozesskette nach der Störung muss angepasst werden. Dies kann z.B. durch eine Änderungskonstruktion, wie der Anpassung der Fügepunktpositionen und der -anzahl, geschehen. In dieser Dissertation wurde eine Auslegungsmethode zur strukturellen elastischen Auslegung punktgefügter Bauteile entwickelt, mit der eine Anpassungskonstruktion, z.B. auf solche Störungen, möglich ist.

Since the properties of the individual parts and the process parameters in manufacturing can scatter, the deviations must be considered in the design. To always deliver these components according to specification, the processes are usually monitored over the entire process chain and the component is over dimensioned. If unforeseeable disruptions occur in the process chain, the component can no longer be produced. Either the malfunction in the process must be rectified, which is not always possible, and the batch that has already been partially produced must be destroyed, or the part of the process chain after the malfunction needs to be adjusted. This can be done, for example, by changing the design, such as adjusting the joints positions and number. In this PhD thesis, a design method for structural elastic designing of point-joined components was developed. With that method a revised design can be defined, e.g. in order to meet unforeseeable disruptions in the process chain.

As a subset of additive manufacturing (AM), the DED process, also referred to as laser metal deposition (LMD), enables precise, layer-by-layer material deposition, making it highly suitable for complex geometries and part repair applications. Critical parameters, such as the laser power, feed rate, powder mass flow, and substrate temperature govern the deposition process, impacting the bead height, width, contact angle, and dilution. Inconsistent control over these variables can lead to defects, such as poor bonding, dimensional inaccuracies, and material weaknesses, ultimately compromising the final product. This paper investigates the effects of various process parameters, specifically the substrate temperature, on bead track geometry in DED processes for stainless steel (1.4404). A specialized experimental setup, integrated within a DED machine, facilitates the controlled thermal conditioning of sample sheets. Using Design of Experiments (DoE) methods, individual bead marks are generated and analyzed to assess geometric characteristics. Regression models, including both linear and quadratic approaches, are constructed to predict machine parameters for achieving the desired bead geometry at different substrate temperatures. Validation experiments confirm the accuracy and reliability of the models, particularly in predicting the bead height, bead width, and contact angle across a broad range of substrate temperatures. However, the models demonstrated limitations in accurately predicting dilution, indicating the need for further refinement. Despite some deviations in measured values, successful fabrication is achieved, demonstrating robust bonding between the bead and substrate. The developed models offer insights into optimizing DED process parameters to achieve desired bead characteristics, advancing the precision and reliability of additive manufacturing technology. Future work will focus on refining the regression models to improve predictions, particularly for dilution, and further investigate non-linear interactions between process variables.</jats:p>","lang":"eng"}],"publication":"Metals","title":"Effect of Substrate Temperature on Bead Track Geometry of 316L in Directed Energy Deposition: Investigation and Regression Modeling","publisher":"MDPI AG","date_created":"2024-12-10T12:13:23Z","year":"2024","quality_controlled":"1","issue":"12","article_type":"original","article_number":"1353","_id":"57699","department":[{"_id":"321"},{"_id":"149"},{"_id":"9"}],"user_id":"49504","status":"public","type":"journal_article","doi":"10.3390/met14121353","main_file_link":[{"url":"https://www.mdpi.com/2075-4701/14/12/1353","open_access":"1"}],"date_updated":"2026-03-20T08:44:28Z","oa":"1","volume":14,"author":[{"first_name":"Deviprasad","orcid":"https://orcid.org/ 0000-0002-3446-2444","last_name":"Chalicheemalapalli Jayasankar","id":"49504","full_name":"Chalicheemalapalli Jayasankar, Deviprasad"},{"first_name":"Stefan","last_name":"Gnaase","full_name":"Gnaase, Stefan","id":"25730"},{"first_name":"Dennis","id":"90491","full_name":"Lehnert, Dennis","last_name":"Lehnert"},{"last_name":"Walter","full_name":"Walter, Artur","first_name":"Artur"},{"full_name":"Rohling, Robin","last_name":"Rohling","first_name":"Robin"},{"first_name":"Thomas","full_name":"Tröster, Thomas","id":"553","last_name":"Tröster"}],"intvolume":"        14","citation":{"ama":"Chalicheemalapalli Jayasankar D, Gnaase S, Lehnert D, Walter A, Rohling R, Tröster T.

By exploring the integration of novel AM techniques such as selective laser melting (SLM) and laser metal deposition (LMD), the study aims to overcome existing limitations like slow build-up rates and limited component resolution. The study’s core objective revolves around the development and validation of a continuous process chain that synergizes different AM routes. In the current study, the continuous process chain for DMG MORI Lasertec 65 3D’s LMD system and the DMG MORI Lasertec 30 3D’s was demonstrated using 316L and 1.2709 steel materials. This integrated approach is designed to significantly curtail process times and minimize component costs, thus suggesting an industry-oriented process chain for future manufacturing paradigms. Additionally, the research investigates the production and material behavior of components under varying manufacturing processes, material combinations, and boundary layer materials.

These two components can therefore be joined using the intrinsic joining technique, which is formed by curing the matrix of the FRP component. In this study, for the hybrid joint, unidirectionally pre-impregnated semi-finished products (prepregs) with duromer matrix resin and micro-alloyed HC340LA steel were used. In order to conduct a detailed investigation, the damage mechanisms of intrinsically produced fibre metal laminates (FMLs), a new clamping device, and a novel pressing tool were designed and put into operation. The prepregs were prestressed by applying a preloading force using a specially designed prestressing frame. Hybrid specimens were then produced and subjected to nanoindentation and a shear tensile test. In particular, the effect of the residual stress state by varying the defined prestressing force on the damage mechanisms was studied. The results showed that no fracture patterns occurred in the interface of the specimens without preloading as a result of curing at 120 °C, whereas specimens with preloading failed at the boundary layer in the tensile range. Nevertheless, all specimens cured at 160 °C failed at the boundary layer in the tensile range. Furthermore, it was proven that the force and displacement of the preloaded specimens were promisingly higher than those of the unpreloaded specimens."}],"date_created":"2024-08-23T06:47:27Z","publisher":"MDPI AG","title":"Development of a Tool Concept for Prestressed Fibre Metal Laminates and Their Effect on Interface Failure","issue":"8","quality_controlled":"1","year":"2024"},{"department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"user_id":"72008","_id":"48643","language":[{"iso":"eng"}],"publication":"Climate Protection, Resource Efficiency, and Sustainable Engineering","type":"book_chapter","status":"public","author":[{"orcid":"0000-0002-1338-810X","last_name":"Akbulut Irmak","id":"72008","full_name":"Akbulut Irmak, Emine Fulya","first_name":"Emine Fulya"},{"first_name":"Hendrik","full_name":"Hanses, Hendrik","id":"64527","last_name":"Hanses"},{"id":"68836","full_name":"Horwath, Ilona","last_name":"Horwath","first_name":"Ilona"},{"id":"553","full_name":"Tröster, Thomas","last_name":"Tröster","first_name":"Thomas"}],"date_created":"2023-11-07T11:07:19Z","date_updated":"2023-11-07T11:14:22Z","publisher":"transcript Verlag","doi":"10.14361/9783839463772-006","title":"Case Study III: Challenges of lightweight design, vehicles, and rescuers","publication_identifier":{"issn":["2703-1543","2703-1551"],"isbn":["9783837663778","9783839463772"]},"publication_status":"published","citation":{"apa":"Akbulut Irmak, E.

In this work, a process is developed that produces hybrid beams with high bending strength in one step based on the compression moulding process. For this purpose, a prototype beam is developed that represents the complexity of real components and is suitable for destructive as well as non-destructive characterisation methods. The prototype beam consists of a functionalised core structure made of glass mat reinforced polypropylene and outer metal belts made of steel and aluminium alloys, which are coated with an adhesive film. A moulding tool and an instrumented production line are developed, with which the hybrid structures are prototypically manufactured. For process optimisation, the joint is analysed mechanically and optically at sample level. Furthermore, component investigations are carried out using three-point bending tests to characterise the structural behaviour of the hybrid beams. It is found that very good joint strengths can be achieved with the one-step compression moulding process. The temperature and pressure control have a major influence on the result.

However, a decisive disadvantage of these composite materials has so far been the high material and process costs, which is why fiber-reinforced plastics are almost exclusively used in small to medium-sized series. Optimization of manufacturing methods is of great importance to reduce the production cost. In this study, two concepts are proposed that can optimize vacuum assisted light resin transfer molding (VA-LRTM) further, leading to a possibility of fully automatic process. Conventional VA-LRTM methods are used to produce complex fiber-reinforced plastics (FRP) and hybrid components. Traditional molds used to produce components via VA-LRTM are sealed using polymer materials to prevent the leakage of matrix system. The seals undergo tremendous amounts of thermal, chemical, and mechanical loadings. Thus, sealings must be replaced in short intervals. In the current study, a concept where sealing is achieved by accelerating the curing of matrix system itself with the help of heating elements and catalysts resulting in a self-sealing approach is proposed. Another concern is mold surface contamination during component production. To address this, a modified automatic cleaning technique based on ultrasonic cleaning was proposed which can be integrated into the production line with minimum modification. Both the proposed concepts were validated and optimized using experiments, simulations, and analytical approaches by producing metal-FRP hybrid shafts."}],"type":"dissertation"},{"_id":"45831","user_id":"49504","department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"ddc":["620"],"keyword":["Compression Molding","Glass Mat Thermoplastics","Hybrid Brake Pedal"],"language":[{"iso":"eng"}],"file_date_updated":"2023-07-03T08:15:04Z","type":"conference_abstract","file":[{"relation":"main_file","success":1,"content_type":"application/pdf","access_level":"closed","file_id":"45832","file_name":"LightMAT-2023_Extended Abstract.pdf","file_size":359467,"creator":"dcj","date_created":"2023-07-03T08:15:04Z","date_updated":"2023-07-03T08:15:04Z"}],"status":"public","date_updated":"2024-03-26T09:19:44Z","author":[{"first_name":"Deviprasad","orcid":"https://orcid.org/ 0000-0002-3446-2444","last_name":"Chalicheemalapalli Jayasankar","id":"49504","full_name":"Chalicheemalapalli Jayasankar, Deviprasad"},{"id":"45538","full_name":"Stallmeister, Tim","last_name":"Stallmeister","first_name":"Tim"},{"first_name":"Julian","last_name":"Lückenkötter","full_name":"Lückenkötter, Julian","id":"45543"},{"first_name":"Thomas","last_name":"Tröster","full_name":"Tröster, Thomas","id":"553"}],"date_created":"2023-07-03T08:23:15Z","title":"In-Mold Assembly of Hybrid GMT-Steel Brake Pedals by Compression Molding","conference":{"location":"Trondheim, Norway ","end_date":"2023-06-23","start_date":"2023-06-21","name":"5th International Conference on Light Materials - Science and Technology LightMAT 2023"},"has_accepted_license":"1","year":"2023","citation":{"ama":"Chalicheemalapalli Jayasankar D, Stallmeister T, Lückenkötter J, Tröster T.
