Preparation, structural, microstructural, mechanical, and cytotoxic characterization of Ti‐15Nb alloy for biomedical applications

Abstract

Titanium and its alloys are widely used in the manufacturing of orthopedic prostheses because of certain favorable characteristics titanium possesses. 1 Specifically, titanium has good biocompatibility, a good mechanical strength/density ratio, and a high level of resistance to corrosion. 2 The titanium alloy most used for orthopedic applications is Ti-6Al-4V, 3,4 but studies have shown that vanadium causes allergic reactions in human tissues, 5 and aluminum has been

Role of Silicon in the Microstructural Development and Properties of Ti-15Nb-xSi Alloys for Biomedical Applications

“…Biomaterials with low elastic moduli are essential for shielding stress reduction, which could lead to early implant rejection 10 . The elastic moduli in Ti-Nb alloys changes with Nb concentration in the form of a W-shaped curve with two minimums at approximately 15wt.% and 42wt.% 11 , and these compositions are an ongoing focus of research [12][13][14][15] . Accordingly, Ti-15Nb is more favorable than the Ti-42Nb alloy due to its lower Nb content, which could potentially reduce manufacturing costs 16 , and its lower density.…”

“…Kuroda and colleagues evaluated the characteristics of Ti‐15Nb alloy, with the aim of using it in biomedical applications to replace implants that fail due to mechanical incompatibility with human bone. The alloy showed good results of mechanical properties and did not show cytotoxic effects 6 …”

“…The alloy showed good results of mechanical properties and did not show cytotoxic effects. 6 Artificial Organs readers are welcome to attend to LASAO meetings and events, as we are sure that you will have an enjoyable and productive experience.…”

Development of Novel As-Cast Ti-Mo-Zr Alloys for Biomedical Applications

“…This new class of titanium alloys has been looking for β-type alloys, as they have lower elasticity modulus, among all classes of titanium alloys 8,9 . Such alloys have been produced with the addition mainly of molybdenum 10,11 , zirconium [12][13][14][15] , tantalum 16,17 , and niobium [18][19][20][21] , which are elements that do not present cytotoxic reactions with the organism.…”
