Özet
New Ti-based alloys have recently attracted great attention in biomedical implementations due to their high strength, good biocompatibility, shape memory feature, low density and corrosion resistance. In this study, Ti-16 at% Nb-4 at% Sn alloy was produced by powder metallurgy for use as a biomaterial. In addition, the effects of sintering temperature and sintering time on the microstructure and mechanical properties of the alloy were investigated. The results indicated that ? phase was dominate and ? phase was seen as secondly phase in the microstructures of the sintered samples. As sintering temperature and sintering time increase, the porosity decreases, and compressive strength raised depending on decreasing porosity. Elastic modules of samples produced via powder metallurgy (PM) are close to that of natural bone; hence, the samples do not cause bone abrasion when combined with bone. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.
