| Abstract | |
In this study, the effect of molybdenum content in Ti-15Zr-based alloys (wt%) was analyzed in terms of crystalline structure, microstructure, selected mechanical properties, and cytotoxicity. The samples were produced by argon arc-melting followed by hot rolling and heat treatment processes. The crystalline structure and microstructure were dependent of both alloying elements (zirconium and molybdenum). Ti-15Zr alloy displayed only laths of alpha ` phase, while the alloys up to Ti-15Zr-10Mo exhibited different proportions of alpha `, alpha `', and beta phases. Molybdenum content higher than 12.5 wt% fully stabilized the beta phase. Vickers microhardness values of Ti-15Zr-Mo alloys were higher than those of CP-Ti due to solid solution and phase precipitation strengthening. Young's modulus values of Ti-15Zr-Mo alloys were lower than those of CP-Ti due to b phase stabilization. Cytotoxicity levels of Ti-15Zr-Mo alloys were within a tolerable range for biomedical purposes. In addition, we observed molybdenum content in Ti-15Zr-based alloys promoted an increase on pre-osteoblast adhesion up to 3 h of adhesion's time. Thus, Ti-15Zr-15Mo alloy presented better combination of properties than some traditional metallic biomaterials. (C) 2018 Elsevier B. V. All rights reserved. (AU) | |
