Abstract Scope |
The difference in melting points and densities of Ti, Nb, and Fe makes it difficult to process. Achieving a homogenous beta alloy with the above-mentioned elements using conventional methods involves melting and remelting up to 10 times followed by heat treatment. This paper explores different solution treatment temperatures and time to optimize the microstructure and mechanical properties of beta Ti-11Nb-9Fe alloy for biomedical applications Produced by Direct Energy Deposition. Elemental Ti, Nb, and Fe powders were tubular mixed with composition Ti-11Nb-Fe (wt.%) to fabricate Ti-11Nb-9Fe alloys via DED at 263J/mm3 energy density. Alloy was ST at 900°, 1000°, and 1100°C for 1 and 2 hours under an argon atmosphere. Samples were characterized by an optical microscope, Scanning electron microscopy (SEM), and micro-Vickers hardness. |
