How-ever, the reliable and cost-efficient joining of aluminium components remains a challenge. Mechanical joining methods, such as riveting, are frequently used in the automotive and aerospace construction industries. Rivets are made from heat-treated steels. Compared to steel, the use of aluminium materials for fasten-ers offers several advantages in terms of joining properties, particularly in terms of recyclability, corrosion resistance and reduced weight of the joined structure. Additionally, the manufacturing process is shorter since aluminium fasteners do not require coating. However, aluminium rivets can often not be used due to the insufficient mechanical strength of the fastener material in relation to the joining component materials.\r\nThis study systematically investigates the requirements for using solid alu-minium self-piercing rivets. The influence of rivet geometry adjustments on the joint quality is analysed using numerical simulation. The results are used to derive and evaluate an optimised rivet geometry for joining pure aluminium sheets. On this basis, solid self-drilling rivets with optimised geometry are manufactured from particle-reinforced aluminium produced in a continuous extrusion process by machining. The integration of particles increases the material’s strength. Exper-imental tests are conducted to evaluate the use of optimised solid self-piercing rivets. The quality-relevant parameters are determined and evaluated based on macrographs of the joints.","lang":"eng"}],"publication":"Proceedings in Engineering Mechanics","doi":"10.1007/978-3-032-23641-8_1","language":[{"iso":"eng"}],"date_updated":"2026-06-16T13:21:39Z","publication_status":"published","title":"Particle-Reinforced Aluminium Solid Self-piercing Rivets for Joining Aluminium Alloy Sheets","year":"2026","author":[{"last_name":"Koch","first_name":"Steffen","full_name":"Koch, Steffen"},{"first_name":"Joshua","last_name":"Weber","full_name":"Weber, Joshua"},{"first_name":"Gerson","last_name":"Meschut","full_name":"Meschut, Gerson"},{"last_name":"Stadelmann","first_name":"Claudia","full_name":"Stadelmann, Claudia"},{"last_name":"Böhm","first_name":"Wolfgang","full_name":"Böhm, Wolfgang"},{"last_name":"Merklein","first_name":"Marion","full_name":"Merklein, Marion"}],"publication_identifier":{"issn":["2731-0221","2731-023X"],"isbn":["9783032236401","9783032236418"]}},{"keyword":["Selective laser sintering","Shelf life","Polyamide 12","powder","PA2200","material ageing"],"type":"journal_article","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"},{"_id":"9"}],"date_created":"2023-03-18T14:28:46Z","abstract":[{"lang":"eng","text":"In the laser sintering technology, the semi-crystalline polymer material is exposed to elevated temperatures during processing, which leads to serious material ageing for most materials. This has already been investigated intensively by various authors. However, the ageing of the material at ambient temperatures during shelf life has not been the focus so far. The need to analyse the shelf life can be derived from an ecological and economic point of view. This work is focusing on the shelf life of PA2200 (PA12). To reduce the potential influences of powder production fluctuations, two different powder batches stored for 5.5 years and 6.5 years are investigated and compared to a reference powder produced 0.5 years before these investigations. Multiple powder analyses and part characterisations have been performed. A significant yellowing and molecular chain length reduction can be derived from the measurement results. Whereas the influence on mechanical part performance was minor, the parts built with the stored powders are more yellowish. As it is most likely that this is due to the consumption of polyamide stabilisers, it can be assumed that these parts will be subject to significantly faster ageing. Therefore, it is still not recommended to use the stored powders for critical parts or light intense and humid environments."}],"publication":"The International Journal of Advanced Manufacturing Technology ","doi":"https://doi.org/10.1007/s00170-023-11243-1","main_file_link":[{"open_access":"1","url":"https://link.springer.com/article/10.1007/s00170-023-11243-1"}],"language":[{"iso":"eng"}],"date_updated":"2023-09-07T11:57:59Z","publication_status":"published","year":"2023","title":"Influence of a prolonged shelf time on PA12 laser sintering powder and resulting part properties","author":[{"id":"71545","last_name":"Klippstein","first_name":"Sven Helge","full_name":"Klippstein, Sven Helge"},{"full_name":"Kletetzka, Ivo","last_name":"Kletetzka","first_name":"Ivo","id":"50769"},{"last_name":"Sural","first_name":"Ilknur","full_name":"Sural, Ilknur"},{"full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim","orcid":"000-0001-8590-1921","last_name":"Schmid","id":"464"}],"oa":"1","quality_controlled":"1","citation":{"bibtex":"@article{Klippstein_Kletetzka_Sural_Schmid_2023, title={Influence of a prolonged shelf time on PA12 laser sintering powder and resulting part properties}, DOI={<a href=\"https://doi.org/10.1007/s00170-023-11243-1\">https://doi.org/10.1007/s00170-023-11243-1</a>}, journal={The International Journal of Advanced Manufacturing Technology }, publisher={Springer}, author={Klippstein, Sven Helge and Kletetzka, Ivo and Sural, Ilknur and Schmid, Hans-Joachim}, year={2023} }","short":"S.H.

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.

Fine powdersare primarily defined by the fact that adhesive and cohesive forces outweigh the weight forces, leadingto mostly unwanted agglomeration (clumping) and adhesion to surfaces. Thereby it gets more difficult touse conventional conveyor systems (e.g. pneumatic or vibratory conveyors) for transport. A rather newmethod for transporting these fine powders is based on ultrasonic vibrations, which are used to reducefriction between powder and substrate. Within this contribution an experimental set-up consisting of apipe, a solenoid actuator for axial vibration and an annular piezoelectric actuator for the high frequencyradial vibration of the pipe is described. Since amplitudes of the radial pipe vibration should be as large aspossible to get high effects of friction reduction, the pipe is excited to vibrate in resonance. To determinethe optimum excitation frequency and actuator position the vibration modes and resonance frequenciesof the pipe are calculated and measured. Results are in good accordance."}],"quality_controlled":"1","page":"733-736","language":[{"iso":"eng"}],"_id":"9972","user_id":"55222","volume":"Sensors and Actuators A 263","year":"2017","title":"Analysis of pipe vibration in an ultrasonic powder transportationsystem","status":"public","author":[{"id":"22130","first_name":"Paul","last_name":"Dunst","full_name":"Dunst, Paul"},{"id":"210","first_name":"Tobias","last_name":"Hemsel","full_name":"Hemsel, Tobias"},{"first_name":"Walter","last_name":"Sextro","full_name":"Sextro, Walter","id":"21220"}],"date_updated":"2019-09-16T10:23:40Z"},{"date_created":"2019-05-13T13:28:05Z","type":"conference","keyword":["crystallisation","hydrophones","piezoceramics","potassium compounds","powder technology","powders","sensors","sintering","sodium compounds","(K0.48Na0.52)NbO3","KNbO3 powder","NaNbO3 powder","crystallization","energy harvesting devices","g33 constant","hydrophone sensor","hydrothermal lead-free (K0.48Na0.52)NbO3 ceramics","hydrothermal method","piezoelectric applications","sintering","Materials","Transducers"],"department":[{"_id":"151"}],"publication":"Ultrasonics Symposium (IUS), 2012 IEEE International","citation":{"ieee":"T.
