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>"}],"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"}],"publisher":"MDPI AG","date_created":"2022-01-10T08:25:58Z","title":"Low Cycle Fatigue Performance of Additively Processed and Heat-Treated Ti-6Al-7Nb Alloy for Biomedical Applications","quality_controlled":"1","issue":"1","year":"2022","_id":"29196","user_id":"43720","department":[{"_id":"158"}],"article_number":"122","article_type":"original","file_date_updated":"2022-01-10T08:27:11Z","type":"journal_article","status":"public","date_updated":"2023-04-27T16:42:19Z","oa":"1","author":[{"first_name":"Maxwell","orcid":"0000-0002-3732-2236","last_name":"Hein","id":"52771","full_name":"Hein, Maxwell"},{"last_name":"Kokalj","full_name":"Kokalj, David","first_name":"David"},{"first_name":"Nelson Filipe","full_name":"Lopes Dias, Nelson Filipe","last_name":"Lopes Dias"},{"first_name":"Dominic","full_name":"Stangier, Dominic","last_name":"Stangier"},{"last_name":"Oltmanns","full_name":"Oltmanns, Hilke","first_name":"Hilke"},{"last_name":"Pramanik","full_name":"Pramanik, Sudipta","first_name":"Sudipta"},{"first_name":"Manfred","full_name":"Kietzmann, Manfred","last_name":"Kietzmann"},{"full_name":"Hoyer, Kay-Peter","id":"48411","last_name":"Hoyer","first_name":"Kay-Peter"},{"first_name":"Jessica","last_name":"Meißner","full_name":"Meißner, Jessica"},{"last_name":"Tillmann","full_name":"Tillmann, Wolfgang","first_name":"Wolfgang"},{"last_name":"Schaper","full_name":"Schaper, Mirko","id":"43720","first_name":"Mirko"}],"volume":12,"main_file_link":[{"url":"https://www.mdpi.com/2075-4701/12/1/122","open_access":"1"}],"doi":"10.3390/met12010122","publication_status":"published","publication_identifier":{"issn":["2075-4701"]},"has_accepted_license":"1","citation":{"chicago":"Hein, Maxwell, David Kokalj, Nelson Filipe Lopes Dias, Dominic Stangier, Hilke Oltmanns, Sudipta Pramanik, Manfred Kietzmann, et al. “Low Cycle Fatigue Performance of Additively Processed and Heat-Treated Ti-6Al-7Nb Alloy for Biomedical Applications.” <i>Metals</i> 12, no. 1 (2022). <a href=\"https://doi.org/10.3390/met12010122\">https://doi.org/10.3390/met12010122</a>.","ieee":"M.
