In particular, the low Young’s moduli reduce the risk of stress shielding and implant loosening. The processing of Ti-24Nb-4Zr-8Sn through laser powder bed fusion is presented. The specimens were heat-treated, and the microstructure was investigated using X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The mechanical properties were determined by hardness and tensile tests. The microstructures reveal a mainly β microstructure with α″ formation for high cooling rates and α precipitates after moderate cooling rates or aging. The as-built and α″ phase containing conditions exhibit a hardness around 225 HV5, yield strengths (YS) from 340 to 490 MPa, ultimate tensile strengths (UTS) around 706 MPa, fracture elongations around 20%, and Young’s moduli about 50 GPa. The α precipitates containing conditions reveal a hardness around 297 HV5, YS around 812 MPa, UTS from 871 to 931 MPa, fracture elongations around 12%, and Young’s moduli about 75 GPa. Ti-24Nb-4Zr-8Sn exhibits, depending on the heat treatment, promising properties regarding the material behavior and the opportunity to tailor the mechanical performance as a low modulus, high strength implant material.","lang":"eng"}]},{"doi":"10.3390/magnetism2020007","language":[{"iso":"eng"}],"date_updated":"2023-04-27T16:46:28Z","publication_status":"published","intvolume":" 2","year":"2022","title":"Orientation-Dependent Indentation Behaviour of Additively Manufactured FeCo Sample: A Quasi In-Situ Study","publication_identifier":{"issn":["2673-8724"]},"author":[{"full_name":"Pramanik, Sudipta","first_name":"Sudipta","last_name":"Pramanik"},{"full_name":"Tasche, Frederik","first_name":"Frederik","last_name":"Tasche"},{"id":"48411","first_name":"Kay-Peter","last_name":"Hoyer","full_name":"Hoyer, Kay-Peter"},{"id":"43720","first_name":"Mirko","last_name":"Schaper","full_name":"Schaper, Mirko"}],"keyword":["General Earth and Planetary Sciences","General Environmental Science"],"type":"journal_article","department":[{"_id":"9"},{"_id":"158"}],"date_created":"2023-02-02T14:29:57Z","abstract":[{"text":"The quasi in-situ indentation behaviour of <110>||BD and <111>||BD-oriented grains in a FeCo alloy is studied in this investigation. The effect of build height on melt pool shape and melt pool size is also studied by finite element method simulations. 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}<111>, {112}<111> and {123}<111>) which is also confirmed by slip lines on the sample surface that are detected by laser scanning confocal microscopy. A high concentration of geometrically necessary dislocations (GNDs) are observed on the adjoining area to the indentation. Local surface topography measurements by laser scanning confocal microscopy confirmed the formation of pile-ups near the indentation.","lang":"eng"}],"publication":"Magnetism","issue":"2","user_id":"43720","volume":2,"page":"88-104","publisher":"MDPI AG","_id":"41503","status":"public","quality_controlled":"1","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={10.3390/magnetism2020007}, 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} }","ama":"Pramanik S, Tasche F, Hoyer K-P, Schaper M.

To differentiate between topographical effects and residual stress-related phenomena, stress-relieved 316L specimens served as a reference throughout the investigations.

Unfortunately, high-strength aluminum alloys such as AA7075 are prone to hot cracking during PBF-LB/M, as well as welding. Both a large solidification range promoted by the alloying elements zinc and copper and a high thermal gradient accompanied with the manufacturing process conditions lead to or favor hot cracking. In the present study, a simple method for modifying the powder surface with titanium carbide nanoparticles (NPs) as a nucleating agent is aimed. The effect on the microstructure with different amounts of the nucleating agent is shown. For the aluminum alloy 7075 with 2.5 ma% titanium carbide nanoparticles, manufactured via PBF-LB/M, crack-free samples with a refined microstructure having no discernible melt pool boundaries and columnar grains are observed. After using a two-step ageing heat treatment, ultimate tensile strengths up to 465 MPa and an 8.9% elongation at break are achieved. Furthermore, it is demonstrated that not all nanoparticles used remain in the melt pool during PBF-LB/M."}],"article_number":"7190","language":[{"iso":"eng"}],"doi":"10.3390/ma14237190","title":"Requirements for Processing High-Strength AlZnMgCu Alloys with PBF-LB/M to Achieve Crack-Free and Dense Parts","year":"2021","publication_identifier":{"issn":["1996-1944"]},"author":[{"id":"77250","first_name":"Steffen","last_name":"Heiland","full_name":"Heiland, Steffen"},{"full_name":"Milkereit, Benjamin","last_name":"Milkereit","first_name":"Benjamin"},{"first_name":"Kay-Peter","last_name":"Hoyer","full_name":"Hoyer, Kay-Peter","id":"48411"},{"last_name":"Zhuravlev","first_name":"Evgeny","full_name":"Zhuravlev, Evgeny"},{"full_name":"Kessler, Olaf","first_name":"Olaf","last_name":"Kessler"},{"id":"43720","full_name":"Schaper, Mirko","first_name":"Mirko","last_name":"Schaper"}],"publication_status":"published","date_updated":"2023-06-01T14:34:46Z","intvolume":" 14"},{"publication_status":"published","date_updated":"2023-06-01T14:33:57Z","article_type":"original","intvolume":" 306","year":"2021","title":"Bioresorbable AgCe and AgCeLa alloys for adapted Fe-based implants","author":[{"id":"44307","last_name":"Krüger","orcid":"0000-0002-0827-9654","first_name":"Jan Tobias","full_name":"Krüger, Jan Tobias"},{"first_name":"Kay-Peter","last_name":"Hoyer","full_name":"Hoyer, Kay-Peter","id":"48411"},{"full_name":"Schaper, Mirko","last_name":"Schaper","first_name":"Mirko","id":"43720"}],"publication_identifier":{"issn":["0167-577X"]},"doi":"10.1016/j.matlet.2021.130890","article_number":"130890","language":[{"iso":"eng"}],"abstract":[{"text":"Implants often overtake body function just for a certain time and remain as an unnecessary foreign body or have to be removed. Thus, resorbable implants are highly beneficial to reduce patient burden. Besides established materials, Iron-(Fe)-based alloys are in focus due to superior mechanical properties and good biocompatibility. However, their degradation rate needs to be increased. Phases with high electrochemical potential could promote the dissolution of residual material based on the galvanic coupling. Silver (Ag) is promising due to its high electrochemical potential (+0.8 V vs. SHE), immiscibility with Fe, biocompatibility, and anti-bacterial properties. But to prevent adverse consequences the Ag-particles, remaining after dissolution of the matrix, need to dissolve. Thus, a bioresorbable Ag-alloy is required. Regarding the electrochemical potential and degradation behavior of binary alloys, Cerium (Ce) and Lanthanum (La) are well-suited considering their biocompatibility and antibacterial behavior. Accordingly, this research addresses AgCe and AgCeLa alloys as additives for Fe-based materials with adapted degradation behavior. Furthermore, degradable Ag-alloys combined with inert implant materials could enable the controlled release of antibacterial active Ag-ions.","lang":"eng"}],"publication":"Materials Letters","type":"journal_article","department":[{"_id":"9"},{"_id":"158"}],"date_created":"2021-09-22T06:49:22Z","status":"public","user_id":"43720","volume":306,"_id":"24790","quality_controlled":"1","citation":{"chicago":"Krüger, Jan Tobias, Kay-Peter Hoyer, and Mirko Schaper. “Bioresorbable AgCe and AgCeLa Alloys for Adapted Fe-Based Implants.” Materials Letters 306 (2021). https://doi.org/10.1016/j.matlet.2021.130890.","short":"J.T.

X-ray µ-computer tomography (CT), electron backscattered diffraction (EBSD), and transmission electron microscopy (TEM) are employed to determine the microstructure on different length scales. Microstructural evolution is studied by performing EBSD of the same area before and after the tensile test. As a result, $$\\langle$$\r\n ⟨\r\n 001$$\\rangle$$\r\n ⟩\r\n ||TD, $$\\langle$$\r\n ⟨\r\n 011$$\\rangle$$\r\n ⟩\r\n ||TD are hard orientations and $$\\langle$$\r\n ⟨\r\n 111$$\\rangle$$\r\n ⟩\r\n ||TD is soft orientations for deformation accommodation. It is not possible to predict the deformation of a single grain with the Taylor model. However, the Taylor model accurately predicts the orientation of all grains after deformation. {123}$$\\langle$$\r\n ⟨\r\n 111$$\\rangle$$\r\n ⟩\r\n is the most active slip system, and {112}$$\\langle$$\r\n ⟨\r\n 111$$\\rangle$$\r\n ⟩\r\n is the least active slip system. Both EBSD micrographs show grain subdivision after tensile testing. TEM images show the formation of dislocation cells. Correlative HRTEM images show unresolved lattice fringes at dislocation cell boundaries, whereas resolved lattice fringes are observed at dislocation cell interior. Since Schmid’s law is unable to predict the deformation behavior of grains, the boundary slip transmission accurately predicts the grain deformation behavior."}],"publication":"Journal of Materials Engineering and Performance","issue":"11"},{"abstract":[{"lang":"eng","text":"The addition of Ag to amorphous carbon (a-C) films is highly effective in tailoring the tribo-mechanical properties and biocompatibility. For biomedical applications, Ag-containing a-C (a-C:Ag) represents a promising film material for improving the biofunctional surface properties of Ti-based alloys. In a sputtering process, a-C:Ag films, with Ag contents up to 7.5 at.%, were deposited with a chemically graded TixCy interlayer onto Ti6Al4V. The tribo-mechanical and biocompatible properties of a-C:Ag were evaluated. The influence of the Ag content on these properties was analyzed and compared to those of uncoated Ti6Al4V.\r\n\r\nRaman spectroscopy reveals that the amount of incorporated Ag does not induce significant structural changes in the disordered network, only a reduced number of vacancies and sp3-coordinated C bonds within the sp2-dominant a-C network is assigned to the films with high Ag concentration. With increasing Ag content, stresses, hardness, and elastic modulus decrease from (2.02 ± 0.07) to (1.15 ± 0.03) GPa, from (17.4 ± 1.5) to (13.4 ± 0.9) GPa, and from (171.8 ± 8.1) to (138.5 ± 5.8) GPa, respectively. In tribometer tests, the friction behavior against Al2O3 in lubricated condition with a simulated-body-fluid-based lubricant is not affected by the Ag concentration, but the Al2O3 counterpart wear is reduced for all a-C:Ag films compared to a-C. The friction against ultra-high-molecular-weight polyethylene (UHMWPE) decreases continuously with increasing Ag concentration and the counterpart wear is lower at higher Ag contents. Compared to a-C:Ag, Ti6Al4V demonstrates lower friction against UHMWPE and higher friction against Al2O3. The a-C:Ag films are not exposed to abrasion by Al2O3 or pronounced material transfer of UHMWPE. The hardness difference and chemical affinity between the friction partners are decisive for the tribological behavior of a-C:Ag. Compared to Ti6Al4V, the a-C:Ag films show antibacterial activity against Staphylococcus aureus, while the proliferation of osteoblast-like cells is reduced by Ag."}],"quality_controlled":"1","publication":"Surface and Coatings Technology","citation":{"apa":"Tillmann, W., Lopes Dias, N.

TiAl6V4 is the most common used titanium alloy particularly\r\nin biomedical applications. TiAl6Nb7 shows promising improvements especially\r\nregarding biocompatible properties due to the substitution of the hazardous\r\nvanadium. This work focuses on the examination of laser beam melted TiAl6Nb7.\r\nFor microstructural investigation scanning electron microscopy including energydispersive\r\nx-ray spectroscopy as well as electron backscatter diffraction are utilized.\r\nThe laser beam melted related acicular microstructure as well as the corresponding\r\nmechanical properties, which are determined by hardness measurements\r\nand tensile tests, are investigated. The laser beam melted alloy meets,\r\nexcept of breaking elongation A, the mechanical demands like ultimate tensile\r\nstrength Rm, yield strength Rp0.2, Vickers hardness HV of international standard\r\nISO 5832-11. Next steps contain comparison between TiAl6Nb7 and TiAl6V4 in\r\ndifferent conditions. Further investigations aim at improving mechanical properties\r\nof TiAl6Nb7 by heat treatments and assessment of their influence on the microstructure\r\nas well as examination regarding the corrosive behavior in human bodylike\r\nconditions.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1002/mawe.202000288","publication_identifier":{"issn":["0933-5137","1521-4052"]},"author":[{"last_name":"Hein","orcid":"0000-0002-3732-2236","first_name":"Maxwell","full_name":"Hein, Maxwell","id":"52771"},{"full_name":"Hoyer, Kay-Peter","last_name":"Hoyer","first_name":"Kay-Peter","id":"48411"},{"id":"43720","first_name":"Mirko","last_name":"Schaper","full_name":"Schaper, Mirko"}],"title":"Additively processed TiAl6Nb7 alloy for biomedical applications","year":"2021","article_type":"original","intvolume":" 52","publication_status":"published","date_updated":"2023-06-01T14:38:03Z","citation":{"bibtex":"@article{Hein_Hoyer_Schaper_2021, title={Additively processed TiAl6Nb7 alloy for biomedical applications}, volume={52}, DOI={10.1002/mawe.202000288}, journal={Materialwissenschaft und Werkstofftechnik}, author={Hein, Maxwell and Hoyer, Kay-Peter and Schaper, Mirko}, year={2021}, pages={703–716} }","short":"M.
