The complex thermomechanical conditions generate non-uniform residual stress distributions. In order to specifically adjust these residual stress distributions, the influence of different process parameters on residual stress distributions in flanges formed by the friction-spinning of tubes is investigated using the design of experiments (DoE) method. The feed rate with an effect of −156 MPa/mm is the dominating control parameter for residual stress depth distribution in steel flange forming, whereas the rotation speed of the workpiece with an effect of 18 MPa/mm dominates the gradient of residual stress generation in the aluminium flange-forming process. A run-to-run predictive control system for the specific adjustment of residual stress distributions is proposed and validated. The predictive model provides an initial solution in the form of a parameter set, and the controlled feedback iteratively approaches the target value with new parameter sets recalculated on the basis of the deviation of the previous run.

The most common way to characterize the additively manufactured lattice structures is via the uniaxial compression test. However, although there are many applications for which lattice structures are designed for bending (e.g., sandwich panels cores and some medical implants), limited attention has been paid toward investigating the flexural behavior of metallic AM lattice structures with tunable internal architectures. The purpose of this study was to experimentally investigate the flexural behavior of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio (PR). Four configurations of lattice structure beams with positive, negative, hybrid PR, and a novel hybrid PR with graded density were manufactured via the laser powder bed fusion (LPBF) AM process and tested under four-point bending. The manufacturability, microstructure, micro-hardness, and flexural properties of the lattices were evaluated. During the bending tests, different failure mechanisms were observed, which were highly dependent on the type of lattice geometry. The best response in terms of absorbed energy was obtained for the functionally graded hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the positive PR (PPR) structure. This highlights the great potential for FGHPR lattices to be used in protective devices, load-bearing medical implants, and energy-absorbing applications.</jats:p>","lang":"eng"}],"type":"journal_article","publication":"Materials","language":[{"iso":"eng"}],"article_number":"4072","keyword":["General Materials Science"],"user_id":"43720","department":[{"_id":"9"},{"_id":"158"}],"_id":"32188","citation":{"short":"O.

An intermetallic layer of Al5Fe2 and Al13Fe4 formed at the interface upon annealing above 500 °C. During in-situ annealing in transmission electron microscope, the layer grew towards the steel side of the interface in tongue-like protrusions. A study of furnace-annealed samples revealed, that the bulk growth of the interface phase proceeds towards the aluminium side. The growth towards steel is a surface effect that takes place simultaneously with the bulk growth towards aluminium. At the beginning of the intermetallic layer formation diffusion of Fe into aluminium prevails, afterwards Al atoms diffuse throught the newly formed intermetallic layer towards steel and the whole interface shifts towards aluminium. The kinetics of growth of the intermetallic layer follows parabolic law in both cases, indicating that the growth is governed by diffusion.","lang":"eng"}],"publisher":"Elsevier BV","date_created":"2023-01-12T09:32:05Z","title":"The influence of surface on direction of diffusion in Al-Fe clad material","quality_controlled":"1","year":"2022"},{"article_type":"original","article_number":"122","file_date_updated":"2022-01-10T08:27:11Z","_id":"29196","user_id":"43720","department":[{"_id":"158"}],"status":"public","type":"journal_article","main_file_link":[{"open_access":"1","url":"https://www.mdpi.com/2075-4701/12/1/122"}],"doi":"10.3390/met12010122","oa":"1","date_updated":"2023-04-27T16:42:19Z","author":[{"first_name":"Maxwell","orcid":"0000-0002-3732-2236","last_name":"Hein","full_name":"Hein, Maxwell","id":"52771"},{"first_name":"David","full_name":"Kokalj, David","last_name":"Kokalj"},{"last_name":"Lopes Dias","full_name":"Lopes Dias, Nelson Filipe","first_name":"Nelson Filipe"},{"first_name":"Dominic","last_name":"Stangier","full_name":"Stangier, Dominic"},{"first_name":"Hilke","full_name":"Oltmanns, Hilke","last_name":"Oltmanns"},{"first_name":"Sudipta","full_name":"Pramanik, Sudipta","last_name":"Pramanik"},{"full_name":"Kietzmann, Manfred","last_name":"Kietzmann","first_name":"Manfred"},{"full_name":"Hoyer, Kay-Peter","id":"48411","last_name":"Hoyer","first_name":"Kay-Peter"},{"last_name":"Meißner","full_name":"Meißner, Jessica","first_name":"Jessica"},{"first_name":"Wolfgang","full_name":"Tillmann, Wolfgang","last_name":"Tillmann"},{"first_name":"Mirko","last_name":"Schaper","full_name":"Schaper, Mirko","id":"43720"}],"volume":12,"citation":{"mla":"Hein, Maxwell, et al. “Low Cycle Fatigue Performance of Additively Processed and Heat-Treated Ti-6Al-7Nb Alloy for Biomedical Applications.” <i>Metals</i>, vol. 12, no. 1, 122, MDPI AG, 2022, doi:<a href=\"https://doi.org/10.3390/met12010122\">10.3390/met12010122</a>.","bibtex":"@article{Hein_Kokalj_Lopes Dias_Stangier_Oltmanns_Pramanik_Kietzmann_Hoyer_Meißner_Tillmann_et al._2022, title={Low Cycle Fatigue Performance of Additively Processed and Heat-Treated Ti-6Al-7Nb Alloy for Biomedical Applications}, volume={12}, DOI={<a href=\"https://doi.org/10.3390/met12010122\">10.3390/met12010122</a>}, number={1122}, journal={Metals}, publisher={MDPI AG}, author={Hein, Maxwell and Kokalj, David and Lopes Dias, Nelson Filipe and Stangier, Dominic and Oltmanns, Hilke and Pramanik, Sudipta and Kietzmann, Manfred and Hoyer, Kay-Peter and Meißner, Jessica and Tillmann, Wolfgang and et al.}, year={2022} }","short":"M.

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"}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","file_id":"29197","access_level":"closed","file_name":"Hein et al - 2022 - Low Cycle Fatigue Performance of Additively Processed and Heat-Treated Ti-6Al-7Nb Alloy for Biomedical Applications.pdf","file_size":6222748,"creator":"maxhein","date_created":"2022-01-10T08:27:11Z","date_updated":"2022-01-10T08:27:11Z"}],"publication":"Metals","title":"Low Cycle Fatigue Performance of Additively Processed and Heat-Treated Ti-6Al-7Nb Alloy for Biomedical Applications","publisher":"MDPI AG","date_created":"2022-01-10T08:25:58Z","year":"2022","quality_controlled":"1","issue":"1"},{"article_number":"142780","article_type":"original","funded_apc":"1","_id":"29811","department":[{"_id":"158"},{"_id":"321"}],"user_id":"43720","status":"public","type":"journal_article","doi":"10.1016/j.msea.2022.142780","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/abs/pii/S0921509322001885"}],"date_updated":"2023-04-27T16:42:08Z","volume":838,"author":[{"first_name":"Alexander","last_name":"Reitz","orcid":"0000-0001-9047-467X","full_name":"Reitz, Alexander","id":"24803"},{"last_name":"Grydin","full_name":"Grydin, Olexandr","id":"43822","first_name":"Olexandr"},{"id":"43720","full_name":"Schaper, Mirko","last_name":"Schaper","first_name":"Mirko"}],"intvolume":"       838","citation":{"bibtex":"@article{Reitz_Grydin_Schaper_2022, title={Influence of thermomechanical processing on the microstructural and mechanical properties of steel 22MnB5}, volume={838}, DOI={<a href=\"https://doi.org/10.1016/j.msea.2022.142780\">10.1016/j.msea.2022.142780</a>}, number={142780}, journal={Materials Science and Engineering: A}, publisher={Elsevier BV}, author={Reitz, Alexander and Grydin, Olexandr and Schaper, Mirko}, year={2022} }","short":"A.

The experimental setup allowed a near-process analysis of the transformation kinetics, resulting microstructure and mechanical properties for a specific process route with a reduced number of specimens. A systematic investigation of the effects of different process parameters on the microstructural and mechanical properties made it possible to reveal interactions and independencies between the process parameters in order to design a partial heating or differential cooling process. Furthermore, the implementation of two different cooling conditions, representative of differential cooling in the die relief method with tool-contact and non-contact areas, showed that the soaking duration has a significant influence on the microstructure in the non-contact tool area."}],"publication":"Materials Science and Engineering: A","title":"Influence of thermomechanical processing on the microstructural and mechanical properties of steel 22MnB5","publisher":"Elsevier BV","date_created":"2022-02-11T17:19:11Z","year":"2022","quality_controlled":"1"},{"publication_status":"published","quality_controlled":"1","publication_identifier":{"issn":["0167-577X"]},"citation":{"chicago":"Tillmann, Wolfgang, Nelson Filipe Lopes Dias, David Kokalj, Dominic Stangier, Maxwell Hein, Kay-Peter Hoyer, Mirko Schaper, Daria Gödecke, Hilke Oltmanns, and Jessica Meißner. “Tribo-Functional PVD Thin Films Deposited onto Additively Manufactured Ti6Al7Nb for Biomedical Applications.” <i>Materials Letters</i>, 2022. <a href=\"https://doi.org/10.1016/j.matlet.2022.132384\">https://doi.org/10.1016/j.matlet.2022.132384</a>.","ieee":"W.

For this, two cellular solids having nested and non-nested structures are designed and additively manufactured via laser powder bed fusion. The primary objective is to design cellular solids which absorb a significant amount of energy upon impact loading without transmitting a high amount of stress into the cellular solids. Therefore, compression testing of the two cellular solids is performed. The nested and non-nested cellular solids show similar energy absorption properties; however, the nested cellular solid transmits a lower amount of stress in the cellular structure compared to the non-nested cellular solid. The experimentally measured strain (by DIC) in the interior region of the nested cellular solid is lower despite a higher value of externally imposed compressive strain. The second objective of this study is to determine the thermal insulation properties of cellular solids. For measuring the thermal insulation properties, the samples are placed on a hot plate; and the surface temperature distribution is measured by an infrared camera. The thermal insulating performance of both cellular types is sufficient for temperatures exceeding 100 °C. However, the thermal insulating performance of a non-nested cellular solid is slightly better than that of the nested cellular solid. Additional thermal simulations predict a relatively higher temperature distribution on the cellular solid surfaces compared to experimental results. The simulated residual stress shows a similar distribution for both types, but the magnitude of residual stress is different for the cellular solids upon cooling from different temperatures of the hot plate.</jats:p>","lang":"eng"}],"publisher":"MDPI AG","date_created":"2023-02-02T14:27:40Z","title":"Additively Manufactured Nested and Non-Nested Cellular Solids for Effective Stress Distribution and Thermal Insulation Applications: An Experimental and Finite Element Analysis Study","quality_controlled":"1","issue":"9","year":"2022"},{"keyword":["General Materials Science"],"language":[{"iso":"eng"}],"publication":"Materials","abstract":[{"lang":"eng","text":"<jats:p>The additive manufacturing (AM) of innovative lattice structures with unique mechanical properties has received widespread attention due to the capability of AM processes to fabricate freeform and intricate structures. The most common way to characterize the additively manufactured lattice structures is via the uniaxial compression test. However, although there are many applications for which lattice structures are designed for bending (e.g., sandwich panels cores and some medical implants), limited attention has been paid toward investigating the flexural behavior of metallic AM lattice structures with tunable internal architectures. The purpose of this study was to experimentally investigate the flexural behavior of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio (PR). Four configurations of lattice structure beams with positive, negative, hybrid PR, and a novel hybrid PR with graded density were manufactured via the laser powder bed fusion (LPBF) AM process and tested under four-point bending. The manufacturability, microstructure, micro-hardness, and flexural properties of the lattices were evaluated. During the bending tests, different failure mechanisms were observed, which were highly dependent on the type of lattice geometry. The best response in terms of absorbed energy was obtained for the functionally graded hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the positive PR (PPR) structure. This highlights the great potential for FGHPR lattices to be used in protective devices, load-bearing medical implants, and energy-absorbing applications.</jats:p>"}],"publisher":"MDPI AG","date_created":"2023-02-02T14:28:34Z","title":"LPBF Manufactured Functionally Graded Lattice Structures Obtained by Graded Density and Hybrid Poisson’s Ratio","quality_controlled":"1","issue":"12","year":"2022","_id":"41499","user_id":"43720","department":[{"_id":"9"},{"_id":"158"}],"article_number":"4072","type":"journal_article","status":"public","date_updated":"2023-04-27T16:46:12Z","author":[{"last_name":"Abdelaal","full_name":"Abdelaal, Osama","first_name":"Osama"},{"first_name":"Florian","full_name":"Hengsbach, Florian","last_name":"Hengsbach"},{"last_name":"Schaper","id":"43720","full_name":"Schaper, Mirko","first_name":"Mirko"},{"first_name":"Kay-Peter","full_name":"Hoyer, Kay-Peter","id":"48411","last_name":"Hoyer"}],"volume":15,"doi":"10.3390/ma15124072","publication_status":"published","publication_identifier":{"issn":["1996-1944"]},"citation":{"apa":"Abdelaal, O., Hengsbach, F., Schaper, M., &#38; Hoyer, K.-P.

As the building height increases, the aspect ratio of the elliptical melt pool increases. Correspondingly, the effect of the laser scan speed on the melt pool shape and size is studied by the finite element method, because, as the laser scan speed increases, the aspect ratio of the elliptical melt pool increases, too. The microstructural characterisation of the indentation area before and after indentation is performed by electron backscatter diffraction (EBSD). Based on the EBSD data grain reference orientation deviation (GROD), calculations are performed to describe the effect of indentations on the neighbouring grain orientations. High GROD angles are detected in the neighbouring grain region adjoining the indented grain. An in-depth slip trace analysis shows the activation of all three slip systems ({110}&lt;111&gt;, {112}&lt;111&gt; and {123}&lt;111&gt;) which is also confirmed by slip lines on the sample surface that are detected by laser scanning confocal microscopy.

Local surface topography measurements by laser scanning confocal microscopy confirmed the formation of pile-ups near the indentation.</jats:p>"}],"publication":"Magnetism","type":"journal_article","doi":"10.3390/magnetism2020007","title":"Orientation-Dependent Indentation Behaviour of Additively Manufactured FeCo Sample: A Quasi In-Situ Study","volume":2,"date_created":"2023-02-02T14:29:57Z","author":[{"first_name":"Sudipta","full_name":"Pramanik, Sudipta","last_name":"Pramanik"},{"full_name":"Tasche, Frederik","last_name":"Tasche","first_name":"Frederik"},{"first_name":"Kay-Peter","last_name":"Hoyer","id":"48411","full_name":"Hoyer, Kay-Peter"},{"full_name":"Schaper, Mirko","id":"43720","last_name":"Schaper","first_name":"Mirko"}],"publisher":"MDPI AG","date_updated":"2023-04-27T16:46:28Z","page":"88-104","intvolume":"         2","citation":{"bibtex":"@article{Pramanik_Tasche_Hoyer_Schaper_2022, title={Orientation-Dependent Indentation Behaviour of Additively Manufactured FeCo Sample: A Quasi In-Situ Study}, volume={2}, DOI={<a href=\"https://doi.org/10.3390/magnetism2020007\">10.3390/magnetism2020007</a>}, number={2}, journal={Magnetism}, publisher={MDPI AG}, author={Pramanik, Sudipta and Tasche, Frederik and Hoyer, Kay-Peter and Schaper, Mirko}, year={2022}, pages={88–104} }","short":"S.
