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"}],"publication":"Metals","language":[{"iso":"eng"}],"keyword":["General Materials Science","Metals and Alloys","laser powder bed fusion","Ti-6Al-7Nb","titanium alloy","biomedical engineering","low cycle fatigue","microstructure","nanostructure"],"ddc":["620"],"year":"2022","issue":"1","quality_controlled":"1","title":"Low Cycle Fatigue Performance of Additively Processed and Heat-Treated Ti-6Al-7Nb Alloy for Biomedical Applications","date_created":"2022-01-10T08:25:58Z","publisher":"MDPI AG","status":"public","type":"journal_article","file_date_updated":"2022-01-10T08:27:11Z","article_type":"original","article_number":"122","department":[{"_id":"158"}],"user_id":"43720","_id":"29196","intvolume":"        12","citation":{"ieee":"M.
